I am a very healthy 63 year old female. Over the last 3-4 years I have had increasing random episodes of double vision. Originally it was once every few months and would last 20 minutes. They occurred only when I was exercizing - usually walking quickly and never when driving or riding in a car. These have slowly been increasing in duration and frequency.
During the last year they have begun happening several times a day and the duration is much longer- hours even. It ranges from slightly overlapping images, to clearly double (2 birds in the sky - when there is in reality one). There are no days when they do not occur now. They generally come, then clear away slowly until the next time.
During the last month or so they have begun to happen when I am still- reading or working on the computer, as well as exercizing or in the car and persist for longer periods.
I do have glasses with a prism and that does help clear it up. I usually only put them on when I am having a problem, since when I take them off the problem is considerably worse for 30 min or so.
My concern is that this is a precursor of something more serious.
My primary physician has sent me to specialists- I have seen 3 eye doctors in one practice (one for cataract surgery) and discussed this with all of them ( no idea of why this is happening), one neuro-opthamologist, and one neurologist. I have been tested for Graves disease, thyroid disease, myasthenia gravis (3 tests- one test was botched by lab), generally cbc was done, had 2 cat scans, and 2 MRIs over the alst couple of years. There have been no problems found- except a cataract in one eye was removed.
Should I let this go and live with it ( I can the glasses w/ prism do help) or is there a possibility of this being a sympton of a more serious health issue that should be further pursued?
