Trihead, I don't want to sound "snarky" -- but, IF you are doing "ok" right now, do you REALLY want to risk becoming a DIABETIC, or getting OSTEOPOROSIS, or doing some OTHER awful harm to your body -- THANK you MR. Prednisone -- just on the "slight" chance of escaping generalized MG? (With MG, IMHO either the disorder hurts you OR the drugs hurt you.

)
I've done quite a bit of research (although probably not as much as your neuro-opth) -- and I've never heard of Pred. preventing Ocular from going into generalized. Probably why your doc saying a STUDY needs to be conducted.
It could be YEARS before you go generalized -- or you may stay ocular FOREVER. As Annie said, you just never know..........
BTW, a YEAR between appointments??? YIKES!! I mean, YIKES!!!!!!! (Even WITH the opportunity for you to call him -- I mean, you are the patient -- you don't know WHAT to "look" for!!)
