question: My eyesight gets worse over the course of the day to where I can t see to read (even with glasses) by evening. I ve been referred for testing for myasthenia gravis by my opthalmologist in the past. I saw a neuro-opthalmologist several years ago and a neurologist within the last year. The neurologist ran some labs, whicChatDoctore back negative. He did some in-office-type testing and offered to prescribe some kind of antagonist (or something like that). I declined at the time because I have prisms in my glasses (because of what my eye doctor has observed re double vision on a few different occasions now) and they seemed to be doing the trick. I moved about 1000 miles away ... and now am really having trouble. The idea that it could be related to myasthenia gravis concerns me. (I am treated for a cluster of other autoimmune problems, but am okay except the overwhelming fatigue right now.) Anyway --- does my lack of focus increasing over the course of the day justify making an appointment to see someone? And if so, with a new opthamologist?
