Question about Eyedrops

Yasar, Mehmet PFC A Co 602D ASB - 31 Jul 2005 01:29 GMT I have mentioned this a couple months ago but can not really believe it is true. A person who claimed to be working as a certified optician suggested me using eye drops for my eyestrain that usually appears after close work and towards the end of the day. She suggested this is over focus and I have most likely protein build-up. Sounds fishy to me because how does Patanol which she suggested relax my eyes from eyestrain???
Here is my valid question though, is there any eye drop on the counter that relaxes the ciliary body or anything to that effect so eye strain is relieved, if I asked the question technically wrong, let me ask this simple way, are there any eye drops one can buy to relax eye strain? I don't think so because then everyone would use eye drops instead of glasses, right? Of course if the myopia is pseudomyopia...
Thanks alot, hope everyone is doing good...

otisbrown@pa.net - 31 Jul 2005 15:21 GMT Dear Yasar,
The meaning of the term "eye drops" is critical.
Some "eye drops" are medical, and I suggest the term "atropine" and "cyclogel" are some medical eye-drops.
The require medical supervision.
An "optician" is not a medical person, an so could not prescribe them, now could you buy them over the counter.
Some "eye drops" or eye-wash, you can, and these are harmless.
The medical "eye drop" that paralyzes the sphincter muscles, is said to "relax" the muscles. These have been used as an "experiment" to attempt to reduce the rate of myopia development.
Since the accommodation system is paralyzed, it makes seeing "blurry" except for one distance -- thus they would be of very limited use.
I am certain the ODs and MD on News Group can provide additional details for your interest.
Best,
Otis

It's an anti-allergy drop and has little or nothing to do with eyestrain. If you have allergic conjunctivitis (easily diagnosed because of the itching sensation it produces), Patanol will help. If not, it wont, or if it does, it's the placebo effect and cheaper artificial tears will work just as well.

I suppose you could use a cycloplegic in conjunction with the (then necessary) reading glasses, but most people would consider that overkill. I think it has been investigated in kids that are developing myopia with mixed results.

No man, I don't have any allergies as far as I know, my eyes never itch.

Sometimes I go to bed and I have the feeling like even my eyes are closed I am straining to see. Kind of thought these drops would relax my eyes and I'd have better vision in the mornings, I usually do have much much better vision in the mornings until afternoons, then blurriness start to sink in due to all the close work of the day, decreasing light levels, etc. Like you said, maybe since I am slightly myopic, I feel and notice the fluctuations more often than other higher myopes.
Thanks Bill...

William Stacy - 02 Aug 2005 15:50 GMT An interesting concept, applying a mydriatic/cycloplegic drop before bed time to assist the relaxing of the ciliary muscle. Not sure if that's been tried. As long as your anterior angles are wide open or not occludable, I see no big risk in a trial of it, say for a week or two.
You'll need to find a somewhat experimental minded o.d.

It's been tried. Me.
Long-term (6+ months) with Mydriacyl, then
[drawing a line here. Mydriacyl has a relatively short half-life. You won't wake up dilated. Below this line, you will. Believe me: you don't want that.]
Some months with Cyclomydril, then
Some months with Cyclogyl, then
Some months with Homatropine, then
Six+ months with Atropine.
All were in an effort to stave off my ciliary spasm and keep me in the workplace. For mild cases, I have no doubt that something like Mydriacyl (Tropicamide) would work.
Very little, however, is known about the possible effects of long-term use of cycloplegics . . . .
William Stacy - 02 Aug 2005 17:54 GMT Right, I forgot about you. I'm pretty sure John doesn't have the extreme kind of ciliary spasm you have, and he's a pilot, so strong dilaters are out. I'm thinking 1/2% tropicamide, or even diluting that down to 1/4% would be pretty innocuous as a trial.

Bill, this will require me to go back to flight surgeon and request this trial right, there is no way I can obtain these drops from /other sources/?? Because I know they will not let me give this a trial, they'd rather go corrective lenses but the refraction is too small.

The problem is convincing them that your idea of trying it at bedtime would "first, do no harm", if you know what I mean. And sneaking it without approval of the FS could obviously get you into trouble. Think what would happen if you had to report early and your pupils were still dilated... Be careful, my friend.

otisbrown@pa.net - 03 Aug 2005 05:19 GMT Dear Yasar,
I found this study where Bedrossian used atropine on a child develping myopia. Here is the report for your interest.
Bedrossian, R.H., THE EFFECT OF ATROPINE ON MYOPIA, Annals of Ophthalmology, 3 (8): 890-899 (In this study of myopia development, accommodation in one eye was prevented with atropine while the other was not. Result: The atropinized eye stabilized, while the non-atropinized eye progressed into myopia.)

> Dear Otis, I am thinking this might not apply to me as I am 28 now, I > believe the development of my eyes should be completed long ago. You are correct.
Please disregard Otis' quote. He is posting a study which suggests that atropine may slow myopia progression. As you realize, this does not apply to you.
Otis does not realize this. Whats the old saying "if you're a hammer, then everything looks like a nail"? Otis can't get myopia prevention off his mind.
otisbrown@pa.net - 04 Aug 2005 03:51 GMT Dear John,
The general question was about whether a paralyzing drug had been used on the eye -- and its effect.
Clearly, this applies to children -- and you can discard it as you wish.
I would never use atropine in this way.
It does suggest the "problems" that John would have in the "military" if he attempted to use any "drug" for the purposes of protecting his vision in some manner.
Best,
Otis

For mild cases, I have no doubt that something like >>Mydriacyl (Tropicamide) would work. >> >> >Why did you get extreme ciliary spams Neil? How is it now? Hmm. That's the big question. Possibilities:
1) I'm very farsighted and have a high degree of astigmatism. Simply trying to compensate for this level of refractive error can induce accommodative spasm, especially if I was undercorrected for any length of time. Glasses require that a farsighted person accommodate more than would contact lenses. (In a nearsighted person, this is the opposite). I wore glasses for the first 20+ years of my life;
2) Neurologic predisposition. Some people may simply be more prone to ciliary spasm than others. True ciliary spasm often presents after motor vehicle accidents or other head/neurologic trauma/disease;
3) Anomalous Lenticular Inelasticity. In other words, if for some reason my lenses have /always/ been less elastic than they should be (the same thing that causes Presbyopia in forty-somethings), then my ciliaries would have had to work exceptionally hard to achieve focus;
4) Genetic predisposition/ciliary hypertonicity. In other words, maybe my ciliary muscles were unusually 'toned' from birth;
5) Some, all, or none of these ;-)
Nobody really knows....
How is it now? I'm disabled. Presbyopia is making/will make it worse.
. . . but ciliary spasm, to my degree, is exceptionally rare. That's why so many doctors failed to diagnose it in my case. My research finally lead me to the diagnosis.

I only know of a half-dozen cases where people with intractable ciliary spasm were prescribed long-term use of Atropine. I literally have not been able to locate the people from this study to see what became of them. Atropine, for example, causes endothelial cell loss (eats away at your cornea).

Eyestrain is a vague term and can have many causes. If you are approaching forty or are moderately hyperopic, extended near work can fatigue the muscles that focus the eyes at near. That can result in discomfort and blur. If you do not have good tear quality, your eyes may be drying out towards the end of the day and that will also cause discomfort and blurred vision. Humans cannot think and blink, when you are concentrating (ie near work), your blink rate will drop from the usual 12 to 15 times per minute to 2 to 5 times per minute. That long interval between blinks will allow the eye to dry; the effect is worse in people with poor tear quality.
Tension in the facial muscles, especially the muscles around the eyes and across the forehead can also be called "eye strain". If you are squinting to read due to blurred vision or if you tend to furrow your forehead when thinking, then you may be tensioning those muscles excessively and will note discomfort.
Are you using contact lenses --- protein build up can happen to contact lenses. When they are coated they will dry out and cause blurred vision and discomfort.
Patanol will help if your eye discomfort is due to allergies. Allergies will cause itchy, burning, watery, dry, "pressure" feelings and, due to the effect of allergies on the tear film, can also cause blurred vision especially when the blink rate is low during concentrated visual tasks such as driving, reading and computer work. Patanol works by acting on the cells lining the eye ball and lids to normalize them so they produce normal tears instead of poor quality allergic tears. If you have eye strain due to conditions other than allergy, Patanol won't help.

I > don't think so because then everyone would use eye drops instead of > glasses, right? Of course if the myopia is pseudomyopia... If your eye strain at near is due to use of the ciliary muscle, it is easy to relax the ciliary muscle without drops by using low power reading glasses for near tasks.
There are no over the counter drops to relax the ciliary muscle. However, if there were, they would cause blurred vision at near and make your near eye strain worse. Some oral medications affect the same part of the nervous system that controls the ciliary muscle and may have some relaxing effect -- of course they would then cause blur at near and increase eye strain. Anti nausea drugs like Gravol and some anti histamines are in that class, they also cause dry eye so eye strain would be increased two ways -- near blur and fewer tears.
Over the counter eye lubricants like Systane, Tears Naturale, Tear Gel, Liquigel will help increase comfort if your only problem is poor tear quality. If your discomfort is due to uncorrected hyperopia or presbyopia, drops (anti allergy or lubricating) won't help but reading glasses will help. Over the counter anti allergy drops are largely ineffective in relieving allergic eye discomfort, prescription anti allergy drops like Patanol do work for allergic eye discomfort.

Red and burning is more likely to be allergy or chemical irritation. Dry eye very often manifests as "strain", "pressure" and blurred vision at near.
Tension in the facial muscles, especially the muscles around the eyes and across the forehead can also be called "eye strain". If you are squinting to read due to blurred vision or if you tend to furrow your forehead when thinking, then you may be tensioning those muscles excessively and will note discomfort.
No not this either.

Patanol will help if your eye discomfort is due to allergies. Allergies will cause itchy, burning, watery, dry, "pressure" feelings and, due to the effect of allergies on the tear film, can also cause blurred vision especially when the blink rate is low during concentrated visual tasks such as driving, reading and computer work. Patanol works by acting on the cells lining the eye ball and lids to normalize them so they produce normal tears instead of poor quality allergic tears. If you have eye strain due to conditions other than allergy, Patanol won't help.
What is a tear film?
The tear film is the layer of tears covering the eyeball If your eye strain at near is due to use of the ciliary muscle, it is easy to relax the ciliary muscle without drops by using low power reading glasses for near tasks. Yes, I use +1.00 or +2.00 depending on the closeness of the work, usually +2.00 for computer and +1.00 at work. Most of the time, I find myself taking them off at work though.
Unless your computer is only about a foot away from your face, +2.00 is too strong for computer use, especially if you are a -0.50 myope. You are likely leaning in closer to see it and that will cause neck and back muscle strain which may result in referred pain in the forehead/ eye area. That amount of plus will also reduce your normal accommodative convergence, leading your medial recti eye muscles to work overtime to keep the eyes aligned. That could be the source of your strain.
Are you more comfortable taking the reading glasses off for near work? If so, leave them off and use artificial tears three to four times a day instead for a few weeks to see if they help There are no over the counter drops to relax the ciliary muscle. However, if there were, they would cause blurred vision at near and make your near eye strain worse. Some oral medications affect the same part of the nervous system that controls the ciliary muscle and may have some relaxing effect -- of course they would then cause blur at near and increase eye strain. Anti nausea drugs like Gravol and some anti histamines are in that class, they also cause dry eye so eye strain would be increased two ways -- near blur and fewer tears. What are the drops you use before your examinations? Suppose I used these drops before going to bed, would it help relax more during sleep and once in the morning would provide better relaxed vision?
The eyes have a variety of natural muscle tone during the various phases of sleep. Interfering with them may well disturb normal sleep and cause more discomfort. The drops would be worn off in the morning. Even if they were not worn off, the relaxed ciliary muscle would provide worse, not better vision for near tasks and you would have increased eye strain. The underlying assumption that you are making is that use of the ciliary muscle is the cause of your eye strain. This is the least likely cause.
Over the counter eye lubricants like Systane, Tears Naturale, Tear Gel, Liquigel will help increase comfort if your only problem is poor tear quality. If your discomfort is due to uncorrected hyperopia or presbyopia, drops (anti allergy or lubricating) won't help but reading glasses will help. Over the counter anti allergy drops are largely ineffective in relieving allergic eye discomfort, prescription anti allergy drops like Patanol do work for allergic eye discomfort. I just got out of shower and my eyes were red and burning, I tried my roommates Visine Tears. I didn't make any difference at all.
Red eyes after the shower can be due to soap, shampoo or even simply water in the eyes. Visine mostly makes decongestants which will not help dry eye. The various kinds of Vision artifical tears contain preservatives that many people are sensitive to. Try the other OTC artifical tears I mentioned.

Dr. Leukoma - 02 Aug 2005 13:56 GMT There are no eyedrops available over-the-counter (at least in the U.S.) for relieving "eyestrain." Moreover, the terms "eyestrain" itself is not specific, and is not a medical diagnosis.
There are drops to relieve dryness, there are drops to relieve itching. There are also drops to relieve something called "lid myokymia," which is the common twitching of the eyelid.
Drops to paralyze or relax the ciliary muscle are called cycloplegic agents. Those will result in blurred vision at near. Basically, any drug that has an anti-cholinergic action -- such as antihistamines, certain antidepressants -- can affect accommodation and make it more difficult to focus.
Another, often over-looked problem that can produce symptoms of eyestrain, headaches, etc., is called convergence insufficiency. It can cause compensatory over-focusing (over-accommodation), and often results in a slight amount of pseudomyopia. It is aggravated by wearing plus lenses. The treatment ranges from eye exercises to the use of nearpoint base-in prism.
As you can see, there are many potential factors involved. Your problem must be very bothersome as you have posted many times.
