Hi
I have had double vision since August. I have taken varied doses of Mestinon, Neostigmin, Prednisone, and Imuran. I am currently on 300 mg of Mestinon and 150mg of Imuran plus just completed 2 treatments of IVIG and I still have double vision. One thing about the steroids, I am 70 years young and the steroids caused me to spend 5 days in the hospital with diverticulitis so if you have a pre-existing condition DON'T take steroids. That said the steroids did help my vision.
Good Luck
Mike
