barn - 03 Apr 2006 03:26 GMT Greetings, I suffer from optic atrophy in one eye. I always have headaches, nausea and dissiness. I use phosphorus iodine in order to shrink my one pupil. I dont see black out of my one eye. I see everything as a washed out paint job. Therefore I have 2 seperate visions battling for dominance. What can I use to block out the signals my bad eye sees Thanks in Advance Barney
Dr. Leukoma - 03 Apr 2006 04:11 GMT Phosphorus iodine? You just mean phospholine iodide.
It seems that rather than shrink the pupil, you would want to completely blur out the vision or else occlude the pupil entirely.

barn - 03 Apr 2006 04:25 GMT Yes you are right. It is phospholine iodide. How would I go about to completely block the blurred vision from my bad eye? It seems my bad eye is pushing itself in the way of the good eye

I had a great disparity in vision between my two eyes, and my glasses caused me to see double. After a couple of years, I was able to see fine with my glasses, since my brain just used the image from one eye. Since I wore contacts (which didn't cause me to see double) seven days a week, fourteen hours a day, I only wore these glasses for a short time each day.

then youll become legally blind in the bad eye due to amblyombia. It is essental to patch the good eye and exercise the bad eye so it gets stronger instead of wasting away into legal blindness!

You are just a regular font of misinformation, Ace. Amblyopia (which my wife has, and she is blind in one eye), is when the brain never learns to see out of one eye. After a certain age, it is considered nearly impossible for the brain to learn. However, like riding a bicycle, once you learn, you never forget.
And patching only works if the vision is correctable. If the OP had correctable vision, don't you think he would choose to correct it rather than block it?
As I posted (and you snipped), back when I learned to block the vision out of one eye, I was wearing contacts 7 days a week and 14 hours a day. The contacts gave me good vision, it was only the glasses that made me see double. I put the contacts in every morning almost first thing (got a cup of coffee first). In the evening, I wanted to take out the contacts before I got too sleepy, so I wore glasses for about the last hour or two of each day.

acemanvx@yahoo.com - 03 Apr 2006 20:08 GMT What is Amblyopia? Amblyopia is commonly known as lazy eye and is where the vision is reduced in one of the eyes because the amblyopic eye and the brain are not working together properly. The eye itself looks normal, but it is not being used properly as the brain is favoring the other eye. In both cases, one eye becomes stronger, suppressing the image of the other eye. In a minority of cases this may result in a reduction of vision in both eyes. It is estimated that three percent of children under six have some form of amblyopia.
With early diagnosis and treatment, the sight in the amblyopic eye can be restored, however if this condition persists, the weaker eye may becomes useless.
Treatments for Amblyopia Amblyopia cannot be correced by glasses or contact lenses and is not due to any eye disease.
If not detected and treated early in life, amblyopia can cause a permanent loss of vision with associated loss of stereopsis (two eyed depth perception). Detection and correction before the age of two offers the best chance for restoration of normal vision. However, treatment can improve this condition even in adulthood
Amblyopia can be treated fairly successfully between the ages of 2 and 6, but the success decreases with age. The best results from treatment occurs between ages 6 mos. to 2 years.
Treatment is usually simple, employing glasses, drops, exercises and/or patching. Though true amblyopia can not be cured (after the age of 6) treatment for the older child is usually successful in improving vision and should be attempted. Treatment of amblyopia after the age of 6 is not dependent upon age but requires more effort including vision therapy. Every amblyopic patient deserves an attempt at treatment.
It should be remembered, that amblyopia causes more visual loss in the under 40 group than all the injuries, and diseases combined in this age group.

What's your point, Ace? That you know how to copy and paste without giving attribution to where you stole it from? It's considered polite to name your sources.

barn - 04 Apr 2006 12:01 GMT Greetings, Thank you for your time and thoughts. I have had this condition for 15 years. I have tried the frosted glasses, the patch and the opaque black lense. Nothing has worked. It seems my bad eye pushes its vision in front of the good eye. I am one of the few that couldnt adjust. So I spend most of my time in low light situations. The more light there is the faster the eye strain headaches and motion sickness arrive. Im looking for some type of medication that will slowly stop the light from entering my right ( bad ) eye . Any Ideas? The iodide works by allowing me more time before the symptoms start.
Dr. Leukoma - 04 Apr 2006 13:44 GMT I'm sorry, but I don't recall you giving us the reason for your optic atrophy. Are you saying that you do not have glaucoma, you do not have accommodative esotropia, and that your physician is using PI soley as a miotic agent?

Sometimes vision comes from inside the eye, and not outside. Is it possible that you have this problem?
The black patch has always worked great for me. After my first retinal detachment, I was on dilation drops for a week. In addition, after surgery for both detachments (about ten years apart), the operated eye was sensitive to light (hurt) and I used a black patch outside. I also patched with a white cotton eye patch when my eyes were healing, both after the detachments and after cataract surgery (both eyes, about five years apart). In every case, the patch worked great for me in blocking the vision.
Perhaps a white cotton patch (they sell these with the bandages at drug stores, and they are specifically for eyes) tucked inside a black patch, would work? The white patch will be right up against your eye, forcing you to keep the eye closed. Between your eyelid and the black patch, there should be almost no light reaching your eye, even in bright sunlight.

barn - 05 Apr 2006 07:58 GMT My optic atrophy was caused by a combination of kerosene and a tolulene based chemical, used with a air pressure gun to clean a printing press. It started as optic nueritis and within a couple of days atrophied. Barn

You didn't say.

Dr. Leukoma - 03 Apr 2006 13:29 GMT First of all, phospholine iodide is only available by prescription. It is used for the treatment of accommodative esotropia and glaucoma. Is your optic atrophy due to glaucoma?
A number of people have offered suggestions, all, some, or none of which may be satisfactory. The occluder patch is the easiest to try, if you don't mind looking like a pirate. The contact lens with occlusive pupil is a custom job, and will be a bit expensive. You probably want to explore these options with your optometrist.

You can get one at any drugstore in the US.
If you wear glasses, you can ask your optician for advice. I don't know if they frost them or what. In the short term, you can just put tape on the lens.

Or you could get a contact lens with an opaque black 'pupil'.
Or, if you can learn to get used to the difference in vision between the two eyes, this would be the best solution long term.
