ally down - 16 Oct 2005 13:50 GMT Hello Everbody!
First let me say Thank you in advance for your advice. You have no idea how much I appreciate it. I AM SO CONFUSED and don't know what to do..
Here is the story..Flash back to two years ago.. My daughter was 6 at the time and the school nurse called to say she failed the vision screening at school and referred her for further testing at an eye doctor. I panicked and immmediately made an appointment. She was diagnosed with mild myopia and a mild astigmatism (20/30 - 20/40 using both eyes). She had never ever complained about her eyes, doesn't sit close, etc. etc. None of the signs were there. The doctor assured me that the eyes were working together. The doctor said to come back in 6 months and have her fitted for glasses as she would be older and more cooperative (she wasn't really doing what he was asking of her and was growing impatient). I went home and scoured the internet for myopia advice and basically decided that glasses were not needed at this time. One Year later - Nurse called again - still failed but at the same level as the year before, she advised I take her to the eye doctor. I decided against it since her eyes hadn't gotten worse.. Now we are in present day.
The nurse called again, Caroline really failed this time. She was 20/50 in one eye and she couldn't get her to cooperate for the other eye ( she guessed it was probably around 20/70 for that eye). She stated that she only had a simple machine to check and further evaluation was needed. when I picked Caroline up at school her eyes looked watery (she is bothered by allergies) and I don't know if it was allergies that bothered her or the nurses persistent tests. I brought her home and gave her my own test using a printed snellen test at 10 feet. She read the 20/40 line with both eyes together. The 20/40 line with right eye and the 20/60 line with her left eye. She did not like covering her right eye, her left eye began to water and she said it was blurry. I checked her for nearness - she read really tiny print at normal reading level with both eyes open and with both eyes individually. My daughter has never complained about not being able to see. She reads fine and her classroom is small so the board isn't far away, etc. etc. She doesn't squint, or tilt her head, or anything like that. Sometimes it is obvious that she can't see as far away as the rest of us, but that is okay. She isn't driving yet, so what is the big deal. I mentioned what was happening with my daughter's eyes to a friend who is an opthamologist. She immediately said that not having glasses prescribed is robbing her of corrected vision and the damage will be permanent, If I don't do something now then her attemtps at correction will be lost forever and they will never be able to correct to 20/20.
I do not know what to do. My child is very active and glasses would be really difficult. She does gymnastics, dancing, karate, etc. etc. It would be a real problem for her. She is not complaining about her eye sight. I don't want her astigmatism and myopia to progress because I didn't get her glasses. If this was your child what would you do?? I want to do everything I can to help her get the best vision possible. Should I accept the minus lenses that I am sure the doctor will prescribe when she is seen on tuesday? Please help me make the best informed deccision possible. My biggest concern that if I don't get her glasses now that her brain won't grow will never be able to see clearly.. could that happen? Am I ruining her eyesight forever by not putting her in minus glasses right away? I am concerned that when she covers her right eye, she says her left eye is a little blurry for things like the eye chart and she doesn't like it when that eye is covered, not the same when she covers the left. I have charted her at 20/40 indoors with both eyes, and 20/70 in her left eye and she says it's blurry but she can read the 20/70 line with her left. Her right eye she can read the 20/40 to 20/50 line.
thank you soooo much, allyson
Dr. Leukoma - 16 Oct 2005 15:11 GMT > Hello Everbody! > [quoted text clipped - 65 lines] > > allyson Vision is very complex. I am only assuming that your daughter has myopia, which is evidently progressing asymmetrically, as one eye is now worse than the other. Furthermore, her vision appears to be at the level beyond what I would consider "borderline." With uncorrected myopia, I am also concerned with the development of convergence insufficiency which can lead the child to bring the book close to her face in order to "crowd out" binocularity. This leads to reading with one eye only.
If this were my child, I would take her to someone who comes highly recommended, and trust their recommendations. If glasses are advised, I would accept them. I would also be very careful about what I said in front of my child about wearing vision correction. Chances are she may have already picked up some negative "messages" -- subliminal and overt, about wearing eyeglasses. Also, it is perfectly OK not to wear glasses for physical activity. If it does become necessary to do so, there are many types of safety eyewear from which to choose, and then eventually contact lenses. As a child, I had to wear eyeglasses, and quickly learned how to avoid being hit in the face.

ally down - 16 Oct 2005 15:46 GMT Thank you so much for your time. My biggest fear is that I accept the glasses with the notion that she wears them for seeing far away - not at school or at sports or close work but that she grows so dependent on them that she can't see without them at all and then sports will be difficult for her (it is so much her life that it would be devastating for her) She is highly functioning now with 20/40 vision using both eyes. If her eyes get worse while wearing the glasses, then she won't be able to go without them at all. She would be a good candidate for contacts due to her sports and level of actviity (this is a child that never is still and always doing something active), but I think she is too young (although she is a very mature 8 year old). She does not bring her close work to her and reads at what looks like a normal distance, she watches tv at a normal distance. There is no signs that her vision is poor other than failing a vision test. My concern is that one eye is a little worse and I don't want any permanent harm done. If I do nothing at this time and wait it out, will be vision decrease so that it won't be able to be correced with glasses. I am so confused and only want what is best for my child but I don't feel like I can make the best decsion without thoroughly educating myself. please help if you can...
Mike Tyner - 16 Oct 2005 16:03 GMT > her vision is poor other than failing a vision test. My concern is > that one eye is a little worse and I don't want any permanent harm > done. Very few people have exactly the same refraction left-and-right. Myopia, by itself, doesn't cause any neurological or other "permanent" harm, and she's too old to develop amblyopia or any other "uncorrectable" condition.
> If I do nothing at this time and wait it out, will be vision > decrease so that it won't be able to be correced with glasses. No, that doesn't happen. Myopia may progress, and probably will, but her vision remains essentially perfect up close.
> I am so > confused and only want what is best for my child but I don't feel like > I can make the best decsion without thoroughly educating myself. > please help if you can... I agree with Anne. Get the glasses and let her wear them when she feels the need. If she's like other myopes, she'll enjoy seeing the TV and blackboard better and decide for herself. I only recommend "full time wear" when it's likely they'll lose the glasses otherwise.

As a parent, I know what I'd do. I'd get the glasses so that she can see what good vision is like and then let her choose to wear them or not. There might be some activities where she would like to see better and then there might be others where it doesn't concern her. If you try to force her to wear them, you will both be miserable.

ally down - 16 Oct 2005 17:19 GMT My question is this - If she chooses to only wear them for movies and tv watcing, will she be harming her eyes by not wearing them full time?? thank you soooo much for your time. In other words, by wearing the glasses for very limited amount - will it be harming her either way?

For example, they have the right to see like you and me. Based upon the results of the eye examination, you should discuss your concerns with her eye doctor -- again, based on the findings.

otisbrown@pa.net - 17 Oct 2005 20:45 GMT > > Wearing properly prescribed eyeglasses has not been shown to be > > harmful. > > What are the causes of progressive myopia? Dear Dick,
The correct answer is:
1. A confined environment -- confirmed with primate eyes.
2. An over-prescribed minus.
That is my $ 0.02 worth.
That is also the "second-opinion".

> What are the causes of progressive myopia? Medical myopia researchers say it's mostly (80-90%) genetic with a small contribution from lifestyle and environment.
Virtually all myopes are born with normal vision, so you could say that virtually all myopia is "progressive", at least until it stops progressing and "levels off".
There are epidemiological associations between myopia and near work, reading distance, intelligence, income, and length of education.
Even so, attempts to modify the course of myopia using lenses or "exercises" have been proven unreliable.

Are there studies where children prone to myopia are required to read with reading glasses (like +2.5, also with prisms to set convergence at infinity)?
TIA for any response.

> Are there studies where children prone to myopia are > required to read with reading glasses (like +2.5, also with > prisms to set convergence at infinity)? Refractive treatment must be measured relative to the subject's own refractive state. Because individuals vary, +250 lenses won't have the same effect on everybody. If you want equal stimulus for each subject, you must give the emmetrope +250 but you must give a -400 myope a special pair of -150 glasses for the same effect. It's accurate to say "+250 add" or "+250 relative to the cycloplegic refraction"
There are studies that show bifocals DO retard myopia. There are other well-done studies that show bifocals DON'T. What is the preponderance of evidence, and bottom line, what's reliable enough for doctors to recommend? Nada. Everybody's looking. There's a guy who's patented bifocal contacts for myopia control.
But good science doesn't recommend any treatment until it demonstrates consistent efficacy. None of the reviews find that myopia control techniques have done so, therefore my own humble opinion is they are "proven ineffective".

I think you know me well enough to know that I'm not engaging to troll, but ... serious question:
People seeking to prevent/reverse/? myopia with bifocals or plus certainly /have/ occasionally advocated the addition of prisms to offset the 'break' in the near vision triad (accommodation-convergence-mydriasis).
Absent that use of prism, though (eg, if somebody merely put dime store plus readers on their myopic kid's eyes), couldn't that disrupt normal fusional amplitudes, potentially harming a developing fusional system?
I know that--despite my high hyperopia and ciliary spasm, wearing plus lenses for near work throws my exophoria into a tizzy, driving excess convergence and accommodation....
TIA,

I got my first pair of glasses when I was four. It was an "AHA!" moment in every sense of the word. "AHA! That green blob is a tree, that's what everybody has been telling me makes LEAVES!" And that sort of thing.
If you believe your daughter has eye allergies get her some Patanol, which is a prescription eyedrop which will treat eye allergies. It takes a couple of weeks of daily use to kick in. Once the Patanol is working get her in for a complete eye exam - promise what you must (within reason) to get her to cooperate with the exam. Take her to a shop with a good selection of CHILDREN'S frames and help her choose a pair she likes.
Once your daughter has glasses on her face and realizes how much nicer it is to be able to see things she will be glad to have them. I know I was.

Dick Adams - 16 Oct 2005 17:44 GMT With regard to the message news:1129467048.688527.8970@g47g2000cwa.googlegroups.com posted by "ally down" <adowning@adelphia.net>
My rant, as follows:
It continues to be a huge mystery why there is so little interest in understanding the causes of myopia.
When I was a kid, developing myopia at a somewhat later age than the mentioned 8-yr. old, I thought I should have some eyeglasses for reading that set my eyes to see my book at infinity, with prisms and positive spherical surfaces. (I did not know about astigmatism then, but probably did not have much of that to start.) That, I thought, would avoid eyestrain when reading. Reading was uncomfortable and I hypothesized that my eyestrain was hurting my eyes.
But the OP describes an outdoorsy child, prior to the age of immersing the nose in books.
I had one kid who became severely myopic, asymmetrically. My theory for the reading glasses was resisted by all. The kid got into a profession where a lot of reading and close work was required, and had to drop out before it was time for her career to end. (Fortunately, marriage was a possibility.)
Looking down the road, it is hard to get the right eyeglasses (if there should be such) for severely myopic persons, particularly if their eyes do not want to do the binocular thing. One does not see nearly as comfortably through thick lenses as thin or none. Or well. And in many cases, the lenses continually need to get thicker and more complicated. The making of complicated lenses is getting to be a lost art, but frames are getting ever fancier.
Dentists today can advise us on avoiding tooth decay (but you may die like a rat, of course). It is a shame that our eye doctors can only help sell us eyeglasses, at least when it comes to myopia and progressive myopia.
There are some who believe that reading through the kinds of eyeglasses prescribed for myopics to correct their distance vision, encourage the further development of myopia. But you will definitely not hear about that possibility from the eyeglasses (contact lens, etc.) industry.

Google around a bit and learn about people like Adrian Glasser, Christine Wildsoet, and academic institutions all over the world who are studying just that.
It's not being ignored. It's not outweighed by the vast eye doc conspiracy. It's just a complicated issue that doesn't lend itself to any quick and easy fixes.

I was severely myopic. There are glasses, contacts and surgery. Take your pick. My aunt had colon cancer. They removed it. How's that for fun? Then she had heart attacks. She's dead.
Too many people die from medical problems.
Not as many go blind, but it's a major problem.
People with myopia can fix it fairly easily, and myopia by itself is completely and easily correctable. Certainly we want to find out why and find better cures, but it's not time to call out the National Guard.
And what about people with hyperopia? Don't they have even worse vision problems? Shouldn't we tackle that first?
Some people are too short. Shouldn't we fix that first?
Some women have breasts that they think are too small. Shouldn't we fix that?

Lots of people do sports with glasses. Some sports don't require them, and then maybe you have the hassle of holding her glasses for her. Although she is young, there are kids who wear contacts at that age. This might be a big hassle for all of you, but it is something you should think about. I don't know about kids, but there are contacts that can be left in for long periods of time. Contacts are wonderful for sports.

I don't like bribing kids to do what they ought to do. However, sometimes that's what parents need to do. I think that this is worth a very serious short time bribe. Maybe not a pony, but riding lessons? (Little girls almost always want to ride horses.) Find out what she really wants, and offer a deal. If the glasses or contacts work, she'll soon not need a bribe to use them. If it doesn't work, you haven't lost a lot.
Be sure to share all this with the eye doctor. There are many solutions. Some glasses are designed specifically for sports. I predict that suitable glasses will help her sports a whole lot, not hurt her.

William Stacy - 17 Oct 2005 14:29 GMT It's not at all certain to me from what you wrote that she is myopic, but it is very likely that she is anisometropic, and your "near test" certainly did not rule out astigmatism, or even hyperopia. Please post the suggested spectacle Rx. That will help a lot and will enable us to say with more certainty what danger, if any, there is in not wearing glasses.

ally down - 17 Oct 2005 18:49 GMT She had a very thorough eye exam about 18 months ago and nothing mentioned about her being anisometropic. What was mentioned was that she had a very mild astigmatism and that she couldn't see as well far away as normal. The doctor was the one that said "her world is very close up and she isn't driving,etc.etc, so to come back in 6 months to a year". It is obvious that her vision has gotten a little worse in a year, but more so in her left eye than her right. Her eye appt is tomorrow but I will not be filling her prescription tomorrow because we have vision coverage on our insurance but you need a voucher before the prescription is filled and I have not recieved it in the mail yet. I will post the RX and ask you very kind generous people for more advice..

p.clarkii@gmail.com - 18 Oct 2005 01:35 GMT children's visual acuity can vary dramatically when testing from day to day. they can have very active accommodative systems.
if she's 20/40 + in one eye and 20/50 there isn't much anisometropia.

That sounds fairly stupid, but every once in a while you run into a doc for whom this sort of scenario makes sense. A friend's mom was better at balancing her husband's insulin dose than the doc (actually a GOOD doc) was, and he admitted it.

Please understand, I want what is best for my daughter. If it's glasses then so be it, if it is not glases, than so be it. What I am trying to do is educate myself, for the sake of my child, so that I can make an informed decision.

We are not "trolls" or undereducated wacko's (my husband and I both hold advanced degrees". I just believe in doing whatever I can to help my child and I need to educate myself in order to do that. I am not an OD, just a loving a parent who has a difficult decsion to make. I know that my child will need glasses, maybe today, maybe in 6 months, I know that day will come. I know that she will eventually want contacts - that day will come. I just want to make sure that putting minus lenses on a child with binocular 20/40 vision is the appropriate thing to do, knowing that the glasses will effect her lifestyle right now at this point in time - she is too young for contacts.
I live in a town where the University is across the street and it is a College of Medicine. Just about everyone I know is affillitated with the medical profession in one way or another. do I take every opinion of their's to heart. No I do not - they are human.. not infallible.
I know that my daughter has a reflective disorder. I know that the OD will prescribe her glasses. I know that he will most likely tell me that she needs them all the time (that is his preference). Do I have to agree with him?

Why wouldn't corrective lenses be the "appropriate thing to do"? Which authority on the subject made you think otherwise? Did you ever admit to the possibility that vision correction might have a positive effect on your daughter's so-called "lifestyle"? Did you know that a number of professional athletes are nearsighted?

I think that you are confusing human fallibility and scientific knowledge. Humans make errors, and scientific knowledge is never complete, but people have been wearing spectacles for hundreds of years. Some of the greatest and most accomplished of our species were nearsighted and wore spectacles. On the other hand, some nearsighted people have squandered their talents, and need a convenient scapegoat.

ally down - 18 Oct 2005 13:13 GMT I am sorry.. I meant refractive - I was typing pretty fast while trying to get the girls ready for school.. Sometimes i think I might have a "reflective disotrder" as in - I don't always like what I see in the mirrior. it is another dark and dreary day here in the northeast and if we don't see the sun here pretty soon I think my eyes are going to glaze over and we might all need glasses..
Speaking of glasse.. Here is my history..long story short
Never needed glasses.. never failed vision screenings.. Went to college.. big big classrooms, board very far away.. started getting bad headaches.. went to ENT - thought it was sinuses, ruled that out, headaches persisted.. still headaches.. time went on, went to eye doctor after everything else was ruled out (at one point I thought I had a brain tumor - headaches were pretty bad). I needed eye glasses - very mild myopia with astigmatism. Got glasses, wore them sometimes, mostly for lecture hall and the movies..but.. being in college, vanity won out and after a couple of years I stopped wearing glasses - eventually I lost them and that was 15 years ago. Last year I had an eye exam - 20/20 no problems. Mild astigmatism with no need to treat unless it was causing me problems. Weird..
I do have an important question that I would love a clear anser to.
What exactly does eye shape have to do with myopia? In laymans terms please. If eye shape is the cause, will the myopia stop progressing when the eye stops growing (after puberty so to speak). Is it strictly an anatomy thing or is there more at work here. Also does anyone know about the trials for perizipine? Just curious..
Again - just trying to educate myself..

But, did the glasses stop the headaches? Wouldn't that be a medically necessary reason for eyeglasses, even though the refractive error was transient (further proof of course that minus lenses do not lead to irreversible or stairstep myopia)?
> What exactly does eye shape have to do with myopia? In laymans terms > please. If eye shape is the cause, will the myopia stop progressing [quoted text clipped - 3 lines] > > Again - just trying to educate myself.. Let's distinguish between axial, or true myopia, and accommodative, or pseudomyopia. The accommodative system is like a spring: it's flexible and has a memory. However, it typically cannot account for more than one or two diopters of myopia, max. Some people have ONLY pseudomyopia, some have ONLY axial myopia, and some have a COMBINATION of both. Pseudomyopia will go away, eventually. Axial myopia will not go away because it is caused by elongation of the posterior eye. The mechanism by which this occurs is not completely understood at this time. Authorities used to believe that all myopia was produced by mechanical stress. Some people still believe that axial myopia is always preceded by accommodative stress, but that number is fast dwindling.
So, in the simplest sense, the relationship between eye shape and myopia is one of variable length. However, two famous myopia researchers, DI Flitcroft and RA Stone have studied eyeball shape, and have come up with some interesting findings regarding one's eye shape and on-axis image quality, and that this image quality may be linked to the development of myopia via a local neuro-regulatory system. We also know that this local neuro-regulatory system can be blocked by certain drugs know as muscarinic inhibitors, such as atropine and pirenzepine. In summary, myopia research is now looking more at image quality and blur as a function of (1) eyeball shape, or (2) accommodative lag plus some other variable(s).

Dick Adams - 18 Oct 2005 17:44 GMT > [ ... ]
> Last year I had an eye exam - 20/20 no problems. Mild astigmatism > with no need to treat unless it was causing me problems. Weird.. What is really weird is that "professionals" still use such a crude measure as 20/XX to describe quality of vision.
Let me give you an example: Last week I had the final check by my surgeon after IOL implants. I read a few lines on the chart, and he exclaimed "excellent!, you have 20/20", and then walked out. Very busy man! Cheerful, hopeful, optimistic! Gone!
Well, I definitely need eyeglasses to read, but +1.25 Walgreens are good, at least for now. I see quite sharply at one meter, and I can guess that I have a quarter or half diopter of unresolved astigmatism in each eye (ears on the full moon). Although I see fine in sunlight, I will definitely need about a minus diopter of combined sphere and cylinder for night driving, if I expect to read the small signs, like street signs and house numbers. Probably I should consider some prismatic correction, too, because my paths of convergence are vertical after horizontal (like rounded "L's" on their sides).
The main purpose of eyeglasses is to see things sharply. There are much better measures of visual acuity than 20/XX. It does make some sense to say which line on the chart one can finally read, and call that line a 20/XX line for the purpose of identifying the angle subtended by the characters (or the linear size divided by the distance to the chart). But, as is apparent at this newsgroup, 20/XX-talk lumps a whole bunch of other sources of poor vision as well as refractive errors.
Our professionals apparently think that we are all too dumb to know what is going on with our eyes, and those of the ones we should try to help, so that may be why they speak to us in this crude 20/XX gibberish. (When you are so old as me, they assume you are senile as well as dumb.)
> What exactly does eye shape have to do with myopia? Eye length is important. Longer eyes tend to be nearsighted, and conversely for short eyes. The shape of the cornea is important, because it behaves as a lens, in addition to the acommodative lens, and because its irregularities are the major causes of astigmatism.
A great deal of the mystery lies an a small internal body called the ciliary process, which appears to be both a muscle and a gland, which may be thought of as circular, and some cartilaginous elements against which it works to allow the eye's lens to relax and round up to a quite convex shape, as it does when the eye finds the characters in a book, for instance.
> In laymans terms please. If eye shape is the cause, will the myopia > stop progressing when the eye stops growing (after puberty so to > speak). It is quite amazing that eyes can see quite well, in some instances, while their owners grows up and eyeballs change shape and length. By my guess, it is due to a long-term accomodative mechanism affecting the anatomical parts that suspend the accomodative lens.
The going wrong of that accomodative mechanism is probably a big factor in bad eyesight. So I think. No, I can't prove it. sh.t, I am not even a professional.
> Is it strictly an anatomy thing or is there more at work here. More, perhaps -- one can envisage a conspiracy of folks who would rather sell you eyeglasses than to try to find out why you need them, and need them ever stronger if you are a typical myope.
> Also does anyone know about the trials for perizipine? Just curious.. I don't know, but I'd advise to leave it alone. A joint every now and then might be good for relieving ciliary spasms, however.

ally down - 18 Oct 2005 19:03 GMT Okay Guys.. here goes..
We are back from the eye doctor with some interesting results. It turns out my daughter does not have myopia. She has an astigmatism. This is what he said in a nutshell: Her eyes are healthy, they are working well together, no lazy eye (I was worried about that and asked him about it).
She does not have myopia. She has astigmatism - one mild eye, one moderate eye. He prescipred glasses and said she should use them while she is reading, doing school work, working on the computer, etc. but does not need to wear them 24/7.
the RX is as follows:
OD: Sphere: +0.50 Cylinder -0.75 Axis 6 OS: Sphere: +1.00 Cylinder -3.25 Axis 158
Let me know what you think..
allyson
Dr. Leukoma - 18 Oct 2005 20:41 GMT Hmmm. That's quite a bit of astigmatism in the left eye. I am mildly surprised that she doesn't have a small amount of amblyopia in the left eye as a result. However, given her prescription, I think she will benefit a great deal from wearing them.
DrG
Dick Adams - 18 Oct 2005 21:42 GMT > OD: Sphere: +0.50 Cylinder -0.75 Axis 6 > OS: Sphere: +1.00 Cylinder -3.25 Axis 158 Kinda makes you think there may have been an injury to the OS. (Which one is that? Why can't they speak English?) Maybe to both.
That is probably the prescription so she could see the ball tossed from far off at her head. For reading, those numbers might be modified with the customary add 2.5.
Then, assuming hopefully that the prescription is correct, her eyes would be under no stress while reading. Should she have bifocals at her age? Probably she would not want them.
As I have mentioned, I believe that the glasses which correct her eyes for distant vision might stress them if used for reading. That is my remembered experience from being a kid at one time.
Eyes which see well, or are corrected to see well, at infinity, will, with +2.5 diopters of additional, correctly focus at ~1/(2.5 meter) or ~16 inches, but think they are watching something off in the distance. It would be better if those eyes were corrected to converge at 16 inches, with mild prisms. That is a usual, and very comfortable distance for reading.
By not having much stress in her eyes during the next 10 or 15 years when she is growing up to be an intellectual person, which involves a great deal of reading, she might arrive at adulthood with eyeglasses whose weight could be born comfortably on her nose (or hanging from her corneas).
Trying to accommodate for reading with uncorrected astigmatism, particularly at the level mentioned, could, I think, be quite deadly for the little anatomic gadgets which make the eye try to focus.
If, as I speculate, the -3.25D astigmatism (need for cylinder) is due to an injury, it may resolve somewhat, and might well be watched for that reason.
My experience, however, is that the glasses you get this time are going to be very close to the glasses you got last time. That is because the practitioner starts by measuring your present glasses, and starts from there, and tends to timid when it comes to changing anything.
It is very unlikely that any eye doctor would prescribe reading glasses for a child, because that is not the mode. I am not an eye doctor. Therefore I recommend that you not follow any advice that may be implied from what is written above.
I have had a recent experience which suggests that a practitioner with an autorefractor can do a better job at refraction that one with the standard stuff. But I am old and implanted and my lenses are immobile. Everyone knows that kids can accommodate, and may be difficult candidates for autorefraction that reason. But even then, a second opinion from an autorefractor might be useful.

the statements that you attributed to your eye doctor at your daughters earlier appointment make no sense at all in reference to her current prescription.
key questions are, what is your daughter's best corrected acuity in each eye when she was looking through the corrective lenses in her Rx. also what degree of stereopsis does she have.
i am conservative. i would recommend something closer to full-time wear. IMHO the amount of astigmatism in her left eye, which is more than I would term moderate, is significant enough to result in amblyopia if she were to go around uncorrected. i would recommend perhaps full time wear except during recess, gym class, sporting events, etc. where the glasses could be lost or broken.
on the otherhand, if her corrected acuities were normal and equivalent in both eyes currently, and her stereopsis is currently normal, then some docs might simply suggest part-time wear and monitoring over time.
ally down - 18 Oct 2005 22:20 GMT IT was two different doctors..
He really didn't seem to think she would want to wear them full time, he really said that it might help for reading and seeing the board and some school work but that she wouldn't want to run in them or walk around in them. I asked what the harm was and he said, no harm in not wearing them full time. He wants to see her in the next six months and then every year. He said that her eyes were working together but that one eye was doing most of the work for reading and he wanted the glasses to help the other eye work (I'm paraphrasing..).. he said her eyes were able to correct and that there was no amblyopia.. I hope that helps to clarify.. We are filling the prescription next week when our vision voucher comes and plan on wearing them for all close work and then it will be up to her.. He said he wasn't surprised that she is bothered by it... whatever that means..
RM - 18 Oct 2005 22:56 GMT Personally, I think it would be optional as to whether she wears them full or part time. If she was wearing them part time I would definetly want to monitor her vision. She could indeed develop refractive amblyopia with this kind of Rx.
In your message you stated:
> He really didn't seem to think she would want to wear them full time, snip
> she wouldn't want to run in them or walk > around in them. snip
> and then it will be up to her You must realize that, as her parent, YOU need to be the one to decide if it is appropriate whether or not she wears her glasses full time or part time-- not her. You will hopefully make that decision based upon the advice of your doctor as he/she monitors your daughters vision over time. It can't be up to whether your daugher "wants" to wear them or not! I have seen countless adults who were amblyopic and told me they refused to wear their glasses when they were a child and now they regret it. You need to make the best decision for your daughter and not let what she wants to do get in the way of the development of her visual abilities. Its hard for parents to be the tough enforcer for kids that need to wear their glasses full time but it's your responsibility.
> He said he wasn't surprised that she is > bothered by it... whatever that means.. Dan Abel - 18 Oct 2005 23:10 GMT > vision voucher comes and plan on wearing them for all close work and > then it will be up to her. It may be totally academic, but these glasses should help for both near and far (I'm not a doctor, and I'm not familiar with the details, so I could well be wrong). I'm just suggesting that she may not want to give them up for far work.
I mentioned contacts a couple of times, but I have some serious doubts now.

ally down - 18 Oct 2005 23:39 GMT would it be possible for her astigmatism to get better in the bad eye? Would wearing the glasses more than not, possibly help?
ally
William Stacy - 18 Oct 2005 23:53 GMT Probably not, short of eventual eye surgery. It's pretty much the shape of the cornea that she was born with. When she gets the glasses, and has worn them a week or two, take her in and ask them to check her stereo vision with them on.
I'd still like to see some unaided and best corrected acuities. "Normal" just doesn't do it for me. Heck, if you have the charts yourself, check her yourself. Be very careful to completely cover the eye you aren't checking, and try to get different series of letters (or maybe use a tumbling E chart) so memory is not a factor, and make sure she is at the proper viewing distance for the chart (usually, but not always 20 ft.) Measure it. Hopefully your numbers will agree with the docs, when you get them.

ally down - 19 Oct 2005 03:24 GMT could he have possibly over prescribed her.. from what I read here it sounds like much more of a problem than he made it sound in his office. He really didn't mention anything to me about possibility of amblyopia over time, or anything like that. He basicaly said that wearig the glasses would probably help her see better and for certain things she will need/want it and for certain things she might not. The end. He didn't tell me to rush out and get her glasses.. immediately - ( I called today to have the vision voucher rushed to me so we could have the glasses soon).
Could she totally lose vision in the eye with astigmatism? I really don't want that to happen.
Is it possible that she will ever be able to wear contacts? (she will most likely want them over glasses in a few years)
Can Lasik help her when she is an adult.?
Thank you so much..

R 20/20 L 20/20
or just 20/20??? By itself it could mean O.U. (with both eyes).
Amblyopia is only an issue if the best corrected acuities are significantly different between the two eyes. And I must disagree with one thing that's been repeated on this thread: If she doesn't wear the glasses, she might develop amblyopia in the futre. I don't buy that. I think there are many reasons she should wear the glasses, but the time for developing amblyopia ex anopsia at age 8 has long since passed, which is why the AOA and others are pushing to get kids' first exams before age 1 year. In infancy, we can prevent a lot of amblyopia. By age 8, she's over the hill so to speak in the amblyopia department, ESPEICIALLY if she is 20/20 R and 20/20 L with correction. Please verify that. I'll sleep better too!

everything is going to be fine. your daughter justs needs to get some glasses and see her eye doc regularly. it's pretty common-- don't worry about it.
if your were to stop taking her for regular visits to the eyedoc, or let her never use the glasses, or lose them and not replace them, then you have a chance of her developing reduced acuity in her left eye over time (i.e. amblyopia). just do what you should do and everything will be fine.
ally down - 19 Oct 2005 04:11 GMT Thank you so much.. you have really helped to calm me down.. I feel like I left the eye doctor feeling really good and now I have gotten TOO much information that has me all confused. We plan on using the glasses as much as possible (whenever she is on the computer, watching tv, reading, doing homework, etc. etc.) I would like her to be able to go out and ride her bike and play without them (she would most likely damage or lose them). I want to do what's best for her and if forcing her to wear them 24/7 is best, then by golly I'll do it.. I just don't want to have to do that. I don't want to feel guilty every time I see her take them off, or decide to go out and play without them. I will be dilligent on her using them for close work. The OD I took her to came very well referred with 22 years in practice, I felt good about him.
Thanks so much for taking the time to calm my fears and bring me back down to reality...

Looking forward to seeing the acuities and stereo (if they didn't do stereo, not to worry, not everyone does, but it would be nice to have... kind of helps with determining how well the two eyes work together. It would be VERY interesting to measure her stereo with and without the Rx in place, after she's worn them for a week or so).
w.stacy, o.d.
ally down - 18 Oct 2005 23:35 GMT I don't think I have that information that you are requesting.. The whole visit took 1/2 hour, the doctor did NOT stress full time wear, he actually made it a point to say when reading or doing school work and then whenever she wants to wear them. He made it sound like it was more like giving the bad eye a chance to work. He told me that one eye was mild and one was moderate, he said there was no myopia. He didn't say anything about corrected or uncorrected. I asked if she could develop amblyopia and he said it was unlikely. He said that it was likely to stay stable. I didn't even here mention of the word stereopsis. He took a lot of time with her in the chair and took some pictures of her eye before she got into the chair. She was very cooperative today.
I am sorry I cannot be more thorough.. I should have taken notes. I do know that when she had the "machine" over her face (with different lenses around each eye), she read the eye chart really well.
hope this helps..
ally
William Stacy - 18 Oct 2005 23:41 GMT Hoping you will be able to get us those acuities. I'd like to know if that left eye is actually 20/20 corrected, because it would not be unusual at all for her to have developed a little amblyopia in that eye. I can't imagine why they are waffleing on full time wear. If my child had that, I gently urge full time wear. She will be able to wear a contact eventually (i'd recommend a soft toric at least for the left, maybe R also). But then again, if she really has got 20/20 corrected in the left, then I suppose I'd let her decide indirectly. If, as I suspect may be the case, she's actually a little weak on the left acuity, I might even have her patch the right eye part time, say an hour a day, but only with the glasses on. If either the corrected acuities or stereo measurements came in weak I might get more agressive with the Rx (as in full time, no ifs ands or buts).

I was so prepared for a myopia diagnosis that I was kind of taken aback.. I do think the eyes corrected very well.. He flipped a little switch on the black machine over her face and her her read the chart - which she did very well. Then he kept saying "better or worse" as he kept flipping switches. I woul d have thought that if he was concerned with full time wear her would have put more stress on it.. He was very casual... He didn't jump up and yell - oh my gosh.. her eye is really bad. He did stress that they were healthy and working together. I will say that he was very nice and gentle and seemed to know what he was talking about.
William Stacy - 19 Oct 2005 00:50 GMT If you want any advice for her on the internet, you have to provide at least 4 numbers:
Unaided visual acuity, Right eye
Unaided visual acutiy, Left eye
Best corrected visual acuity, Right eye
Best corrected visual acuity, Left eye
He may abbreviate these like UVA, BVA, OD (for right eye), etc., but you should get some numbers that look like 20/20, and they may have little minus or plus signs after them. If he has stereo acuities, great. But I doubt it from your description. If so, they would look something like 30" or 120" which are seconds of arc, and it's just one number, not separately like the 20/ numbers.
good luck

:-) Very often in life, we severely oversimplify things. That's not a problem, as long as we all understand that. I complained to my OMD about the Snellen test before my first cataract surgery, and he fully admitted that there were serious flaws. However, he said that it was better than anything else, and was a very useful first step.
If you read this group for a while, you'll find that the 20/XX is what the patients all talk about, because that's what they were told. The doctors here don't want to hear about it. It isn't very useful information to them. Just read this thread for an example. OP wants to know what to do with her daughter, who has 20/XX vision. The reply from the ODs is that they don't have a clue, what's her prescription? Endless back and forth, lots of discussion of myopia, but the OP doesn't have a prescription. So, now we get a prescription, and she isn't myopic at all!
> The main purpose of eyeglasses is to see things sharply. There are much > better measures of visual acuity than 20/XX. It does make some sense Try reading this group, over and over again the ODs repeat that 20/XX is a small piece. What's important is, "which is better, one or two?".

Almost all animals have eyes, and, for the most part, if they do not see well, they do not grow up.

I think that means that, if your child's eyes are corrected with eyeglasses so that each of them sees the 20/20 line on the chart, there is little possibility that one eye may give up and go south.

The definition of amblyopia requires a difference of at least 2 snellen acuity lines between the eyes WITH BEST CORRECTION IN PLACE. This definition ignores the existence of "bilateral amblyopia", which to me is an oxymoron and a misnomer. There is no evidence that I know of that amblyopia ex anopsia can develop after early childhood.

I'm replying to this old thread regarding your definition of amblyopia. If a patient has a BCVA, reading at a slow pace, 20/25-2 in the left with no ocular disease accept for higher refractive error and 20/15 in the right in a normal pace, does this still fit this definition?

ally down - 19 Oct 2005 16:25 GMT Good morning everybody!
I just got of the phone with the OD. Here goes: Both eyes corrected to 20/20. There is NO amblyopia. She does not have myopia (these are questions I had asked him). He stated again that he would ilke her to wear them for close up work, reading, school work, and if she wants to wear them all the time, she can - no harm no foul, but he would LIKE her to wear them for reading and computer work altogether. He thought her astigmatism would remain fairly stable - said it was something she was born with, etc.etc.
Also, I forgot to ask this one question and I don't want to call him back.. Why does the beginning of her prescription start with a +.. please simplfy for me. If the + is there doesn't that mean that things far away will be blurry...
I'm still confused.. the more I learn the more confused I get..

I'm not happy with eye doctors, because they can't agree on how to write down an eye prescription. I think that this method is particularly confusing. A "plus" means one thing if there is no second number, but something different if there is.
So, your daughter is not myopic, and not hyperopic. She is astigmatic. Her vision problems will cause problems at any distance, not just near or far.

At her age, with numbers that small, it's a non-issue. The second number for each eye is the amount of astigmatism. That's the cause of the blur. If there is myopia in your family, she could yet develop that. But that's another story. Another thread... Glad it all worked out.

This means that--aside from her astigmatism which creates blur regardless of proximity--things at distance will be clear; things at near will require her to 'accommodate' (use her ciliary muscles to change the shape of the lens).
Hate to thicken the soup, but ... have we already determined whether this was a cycloplegic (dilated with eye drops) refraction or not??
 Signature Live simply so that others may simply live
William Stacy - 19 Oct 2005 17:01 GMT Ok lets dissect it one more time:
Her refractive errors are:
OD: Sphere: +0.50 Cylinder -0.75 Axis 6 OS: Sphere: +1.00 Cylinder -3.25 Axis 158
The right eye is actually MILDLY hyperopic along the 6 deg meridian (almost horizontal) and is slightly myopic on the opposite (almost vertical) meridian, with the .75 cylinder causing slight blur at all distances.
The left eye is slightly more, but still MILDLY hyperopic along the 158 deg. (about 4:00 o'clock to 10:00) and MODERATELY MYOPIC (-2.25) along the opposite meridian. The 3.25 cyl causes substantial blur at all distances.
Actually, overall she is very slightly hyperopic in the right eye and mildly myopic in the left, by spherical equivalent (averaging all meridians).
So her blur is caused by her astigmatism, not the plus part of the equation. She is NOT more blurred at far than near, and the opposite is likely. Now that I've looked at it again, I think she probably is "going myopic" as we speak. Time will tell.

Mike Tyner - 19 Oct 2005 18:46 GMT > should I now be worried that she is > miopic and I should look at prevention.. Understand that "myopia prevention" is like the Holy Grail. Everyone's been looking for it and nobody's found it, except atropine-like eye drops. If you want to worry over it you're looking too hard for things to worry about. When you find something that works, please tell us, but tell us how you know it works. I prevented myopia in my kids by erecting a totem pole in my front yard to ward off evil spirits. It also does an excellent job of keeping the elephants out of my garden. I know it works because there's no myopia and no elephants. What other proof do you need?
Your daughter doesn't have myopia. She has about a 1 in 4 chance of developing it, like every kid in this country, somewhat higher or lower depending on her genetics, her ethnicity, and a tiny contribution from her environment. Whatever you do will make very little difference, so why worry? Many myopes are happy to be that way when they reach 45.
About all you can do is keep her from reading with her nose in the book. Or better still, don't let her read?

You stress too much.
There is no proven prevention for astigmatism, myopia, or any refractive error. Your eye is simply going to do whatever its going to do. Much of it is genetic, and whatever isn't has never been determined sufficiently to plot out a preventative treatment plan. Simply take her to the eye doctor annually and change her prescription to keep up with the natural changes that occur in her refractive error. You cannot influence the changes. And changes are quite commonplace in adolescents.

Your daughter is fine. She has astigmatism. In general, when a persons vision is blurry its usually due to nearsightedness, farsightedness, or astigmatism (or a combination). In your daughters case its astigmatism. It simply means, most likely, she has an irregular curvature to her corneal. NO BIG DEAL! Just have her wear her glasses and take her to see her eye doctor when scheduled.

Anisometropia is "a condition of unequal refractive state for the two eyes, one eye requiring a different lens correction than the other.
In the condition of antimetropia the refractive errors of the eye are of opposite signs and amounts as in: OD +3.00 and OS -4.00.
Isoanisometropia is defined as A condition of equal refractive error but with differing dioptric power.

I find anisometropia of interest because I used to have it Real Bad. Furthermore, it was my choice to have it! I had it for five years, after my first cataract surgery and before the second. I was plano in the right eye, and as bad as -10D in the left. Because of this, I had already switched to contacts, which eliminated the problem.

I sort of agree, but I'm less adamant than I used to be on this. Of course you get a more thorough exam if the eyes are dilated, and it does help nail down the presence/absence of ciliary spasm. But if the doc is really skilled, that final Rx is probably going to be based more on the manifest than the cycloplegic. If the skill/confidence is lower, the cyclo is a must. Also, if the patient is not a great examinee, cyclo can be a life-saver.
On ally's posts, this kind of Rx is expected to provide lukewarm reception from an 8 year old. Glad to hear she'll wear them at least part time, but I don't think I'd force too hard. Gentle persuasion is best.

I recall my experiences when, at 8, I started to wear glasses & at some point, was sent to live with my aunt for a half-year, after having chicken pox.
The teacher at the new school made it mandatory that I wear my glasses which I "sometimes forget" to bring it with me; was sent home to get it. I found that I was able to take my time retrieving my glasses without reprimands when it took me 1 or 2 hours to get them even tho it was only a 5 or 10 min walk.
I did find that "forgetting" my glasses was a highly "convienent" situation. Kinda miss those "good old days" when I can "officially" miss school time so often......

To reply:
Otis> This depends on who is making the measurement. When Dr. Colgate made the measurements he confirmed his vision cleared. Opinions differ on this subject.
Dicky> What does "cleared" mean in this context.
Otis> "Cleared" in this context means that he read his eye-chart at 20/70, and by INTENSIVE use of a +2.5 diopter lens, slowly cleared his distant vision to 20/20. (This result is consistent to primate-eye studies -- as the "second-opinion".)
Dicky> Do you mean that he could read lower lines on the charts.
Otis> Exactly -- how else could you tell?
Dicky> At what distance?
Otis> Stirling Colgate has a Ph.D. in physics. He knew the standard distance is 20 feet, and the size of the letters.
Dicky> Was he reading through eyeglasses?
Otis> He "caught" his vision as stated, and realized that he personally had to take care of it himself. i.e., he realized the nature of nearsighedness was the NATURAL eye adapting its refractive state to its average visual environment. By ending the "near" environment with a plus lens -- his distant vision slowly cleared. This would only be possible because the natural eye CONTROLS its refractive state to its AVERAGE visual enviroment.

Perhaps you might be interested in my latest theory:
Now that the pocket movie viewer is available, the next thing will be the eyeglass viewer. The eye guys will be so busy fitting these little viewers into eyeglasses that refractive corrections will take a total back seat. Nobody will care because the real world will totally disappear behind movies. Maybe drivers watching movies as well as gassing on cell phones.
Probably a good thing for the eye guys, because I am guessing that they are all about to be obsoleted by the next generation of autorefractors.
Thank you for your response.

P.S. My guess has been that myopia is due in part (probably mostly) to stretching of anatomical elements which succeed in the well-functioning eye to keep its relaxed focus at infinity. That stretching, once beyond the elastic limit of said elements, would not likely be reversible. Thus, my proposal for positive lenses would be preventative, not therapeutic. It is for reading glasses, positive with respect to the distance correction, based on a competent prescription to correct refractive errors, and prisms to point the eyes straight ahead when focused on the work (converge at infinity). I do not imagine I am the first to propose that.

But I could hope, for them, that they would inelastically stretch far enough, so that their eyes would come to rest at infinity. Then their eyes would function normally, and they would not have to work so hard to focus close.
But they can't do it. Or, if they did, you would not notice them as hyperopes.

p.clarkii@gmail.com - 23 Oct 2005 01:18 GMT so the point is that excessive accommodative stress does not induce myopia, or hyperopes would all become less hyperopic. they don't, and in fact at middle age they usually reveal increased hyperopia.
another point-- why do uncorrected myopes, such as children who are -1.50 and refuse to wear their glasses, become more myopic. if your myopic then you don't stress your accommodative system so you wouldn't expect them to get worse. yet they do, at the same rate as those who do wear their glasses. same is true for kids who are given bifocal.
hell, kids who are given excessive minus lenses so they have to overstress their accommodative mechanism also don't change any more that those with their exact prescription.
are you getting the feeling that it's pretty clear that accommodative stress doesn't play a role in myopia progression in humans? if so, then you are already leagues ahead of our good buddy Otis.
otisbrown@pa.net - 23 Oct 2005 03:41 GMT Dear Dicky,
I have friends in optometry and ophthalmolgy.
I set "professional limitations. I define this as follows.
I DO NOT deal with the great mass of humanity walking in off the street.
The public wants that "instantly sharp" vision, and so it is provided. That is "optometry" and that is how it has been for at least the last 150 years. I do not propose to "chage" it.
In fact Dr. Raphaelson spelled this out with stark clarity in "The Printer's Son", there the plus was indeed successful, and the parents -- not understanding the necessity of it -- totally rejected this intelligent use of the plus -- for prevention. That DEFINES but the problem -- and the fact that these ODs can never achieve a "solution".
But I simply report the fact that the nautural eye is a dynamic device, and is a "control system". When you respect the natural eye is this manner, then you get accurate scientific results. But that becomes a matter of judgment of the scientists who are conducting this type of review.
This respect for scientific facts, however can never be "reduced" to a matter of dealing with the general public -- and I don't propose to do it.
My proposal was for my immediate relatives who had the insight to "work" the preventive measure -- and personally verify their vision as passing all legal VA requirements. This they did. It certainly was not easy, and reflected on their motivation in this issue. The REAL SKILL and ability was in them.
To further respond:
Dick> P.S. My guess has been that myopia is due in part (probably mostly) to stretching of anatomical elements which succeed in the well-functioning eye to keep its relaxed focus at infinity.
Otis> It is just easier to say that when you take a population of primate eyes -- and place them in a more-confined environment, the refraction of the "confined" primates moves in the direction and approximate magnitude of the "confined" environment -- in diopters. This is a NATURAL process -- and can be verified by any scientists who wishes to make this meaurement effort of the NATURAL eye's behavior. That is just the way it is. This is an expected result -- there is no surprise to is. It would be very surprising if this result DID NOT OCCUR.
Dick> That stretching, once beyond the elastic limit of said elements, would not likely be reversible.
Otis> That is true. The only possiblity is prevention -- as suggested by the scientific work of the Oakley-Young study.
Dick> Thus, my proposal for positive lenses would be preventative, not therapeutic.
Otis> That is my position also. It puts "responsibility" on the person himself to make THAT kind of choice. Not easy at all. But the consequences of NOT doing it are as you state.
Dick> It is for reading glasses, positive with respect to the distance correction, based on a competent prescription to correct refractive errors, and prisms to point the eyes straight ahead when focused on the work (converge at infinity).
Otis> It is my belief that a person educated as to the true-facts concerning the natural eye's behavior -- can teach himself how to use the plus. I believe that the "prisms" are not necessary -- and very cumberson. It is hard enough to help the person understand this type of choice -- indeed. Most people will not respond to this -- at all. So the ODs have NOTHING TO WORRY ABOUT.
Dick> I do not imagine I am the first to propose that.
Otis> It is not difficult to propose a preventive solution -- under the person's control. The "reality" is that most people have NO INTEREST in "protecting" their distant vision, and so eventually, there is no choice but to wear a minus lens -- when the eye-chart goes below 20/50 or so.
As always, the issue is more a preception that the natural eye is a "dynamic" system, rather than a "medical" preception. Please enjoy our pleasant analytic reviews of the natural eye's proven behavior. (In terms of measured refractive-state -- not in terms of "error".)
Best,
Otis

Ooh, yes! I am intimately familiar with that, and with progressive myopia, and with cataracts.

But I do not think that they should stand by idly while their kids' eye doctors, when it comes to eyeglasses, play the same games with them as their eye-doctor daddies and granddaddies did in their day.

I could imagine that focusing (accommodation) and convergence (triangulation) are related, in properly-functioning eyes, as they are in an automatic rangefinder camera. I would suspect that reading glasses placed on the noses of kids should have base out prisms as well as whatever other necessary corrections. I do continue to feel that reading glasses might be useful where progressive myopia is a possibility.
The OP's girl has one eye good enough for distance and probably will not wish to wear glasses in public. If given eyeglasses for reading, should they be the same as those that would be given her for distance seeing?

Check your history. Our daddies and granddaddies used plus lenses, bifocals, contact lenses, incantations, and all sorts of apparati. We don't, because none of it has worked so far.

The theory would be that long-term accomodation (changes in the focusing range as the eye grows) is related to the ciliary process, and involves a irreversible stretching of collagenous elements, which, for us myopes, for one reason or another, goes too far. Usually, I suspect, myopia is due at least in part to reading or to other close work. Undoubtedly the theory is not new or unique, but I did come by it independently. It is based on the history of my own eyes and some education in science. And, to some extent, on reading, and on observations among my colleagues.
I did get finally succeed to download the article you suggested I read, http://www.optometrists.asn.au/gui/files/ceo865276.pdf and am reading it carefully. It seems to say that eyeballs may adapt to changes during early years to adolescence, by growing longer in response to certain signals, so as to keep seeing well. It seems to suggest that a way to prevent the development of myopia might be to prevent the eyeballs from growing too long, which they might do if the get their signals mixed. Studies on chickens are described.
Well, I might mention that most of the myopia I suffered occurred during adulthood, not counting the 2nd sight phenomenon in later years. In any case, I do not think the eyeballs grow longer to any appreciable extent during adulthood.
The conviction that myopia is caused by too-long eyeballs won't seem to go away, and must be convenient for persons dedicated to the eyeglasses solution. Maybe there is a study somewhere which will show me that everybody with long eyeballs is myopic?

[quoted text clipped - 38 lines] > -- > Dicky Dick, I don't think you read so well. The discussions in this group have included axial and accommodative myopia. Either one, or both, can exist in a given individual. The evidence that "axial" myopia is caused by elongation of the posterior chamber is so well-established that it is beyond discussion. Whether you choose to believe it or not makes no difference. And, furthermore, it goes almost without saying that there are and have been various "solutions" for the problem ranging from vision therapy, biofeedback, and "Bates" to drugs, eyeglasses, contact lenses, and surgery. The latter three are optical solutions, and only the optical solutions have been found to be reliably and universally effective. And that's just the way it is, Dick. Nature really doesn't care what you think.

There is a statistical association between reading and myopia. That's more than a theory, it's observed fact. The problem is that fooling the eye with lenses, so that reading is done at virtual infinity, doesn't reliably interrupt the process.
>Well, I might mention that most of the myopia I suffered occurred >during adulthood, not counting the 2nd sight phenomenon in later >years. In any case, I do not think the eyeballs grow longer to >any appreciable extent during adulthood. No. They reach about 90% of adult size by puberty.

I don't know the citations but ultrasound measurements show that axial growth outpaces corneal flattening as myopia develops.

otisbrown@pa.net - 20 Oct 2005 16:34 GMT Dear Dicky,
There was a Dr. C. Prentice (a long time ago) who deduced what you stated.
He recommended the use of a strong plus for all close work -- for myopes on the order of -1.25 diopters or so (about 20/70).
He produced successful results, but what he said was that the process is "tedious" for the person, and their intelligence is clear on the subject, it is almost impossible to get them to use the plus "correctly".
That seems to be the "sticking" point more than anything else.
PLEASE do not take this as a medical statement. This is just and observation of the dynamic behavior of the natural eye.
Best,
Otis www.myopiafree.com

Surely you know that the range of eye sizes among humans is very narrow. Most non pathologic eyes are about 22 mm in diameter. Maybe you're thinking of the amount of eye that is visible between the lids? Lid aperture varies, for sure, but behind those lids sits a 22 mm ping pong ball, in most cases...

My wife has amblyopia. There's nothing wrong with her right eye, she just never learned how to use it and now she's too old to learn. Seems a little odd to me, but that's how it is.
A similar thing happened to my son. He had hearing problems when very young, and so never learned how to say certain sounds. He's now 22 and still has speech problems. We knew that kids with hearing problems develop speech problems, so we put him in speech therapy starting at age 3.

Seems > a little odd to me, but that's how it is. It's always the simplifications that get people wondering. What's really up with amblyopia is that we have 2 eyes and in order for the brain to "fuse" the separate images from each into one useful image, it develops a very fine alignment ability. This get messed up when one eye can't line up (strabismus) or when one eye is out of focus (anisometropia). Not being chameleons, we cannot focus our eyes independtly, only in a "yoked" fashion. So what does the young, developing brain do when faced with strab or aniso? It has a choice. Ignore one image (the blurred or misaligned one), or see double. Double vision is not a happy thing for the brain, so it goes so far as to actually supress the central input from the amblyopic eye. Doing this in the first 5 years of life basically causes the brain to never learn how to aim the amblyopic eye accurately: amblyopia ex anopsia. Sometimes agressive therapy on such an eye can actually cause the diplopia (double vision) that the brain was trying to avoid in the first place.

I want to thank everyone who has posted about my wife's amblyopia. However, she is very clear that contacts aren't an option, and I don't see that anything else would help.

Why would that be? Are you quibbling about "whole life"? Another oversimplification. She was diagnosed with amblyopia at the age of 10. She was treated, but frankly, wasn't compliant. She is now 55.
I saw the DMV form that the OD filled out. It was pretty clear.

As someone else posted, glasses will indeed affect her lifestyle. For one thing, she'll be able to see better. I firmly believe that the reason that my wife and I were so bad at sports is because we just couldn't see.
As for contacts, I don't believe that there is any age limit. Certainly it would be more difficult at her age, but somebody at work said her granddaughter, who was just a little baby, was getting contacts. I don't know how well they work, but there are tools to help insert and remove contacts.

There are scientific facts, and there are opinions based on those facts. You know your daughter better than the OD, but the OD knows how things work for most people better than you do. My suggestion is that you find out *why* the OD recommends certain things, and then you can decide if your family situation fits. As someone posted, a good reason to wear glasses all the time for a kid is that otherwise they lose them.
