Topamax has been known to cause "eye" problems. After being on Topamax for 3 years (last year) for me it was "dry eyes" & an "eye infection". Needless to say, I was not a happy camper.
Both easily cleared w/meds.
I notified my Neurologist however, I went straight to an eye doctor & had the eye doctor mail/fax the findings to my Neurologist.
My eyes (eye sight) are more important to me than a migraine.
I wouldn't wait if I were you.
Good Luck!
