I have been on Topamax for almost 2 years. I have been on 150mg since July 2006 when my migraines started changing and getting worse. I started having tingling/numbness under my right eye (also where my migraines are concentrated). I also started having fuzzyness around objects. I describe it as someone putting a water droplet in the middle of my right eye. I was wondering if anyone else has had this? My doctor is sending me to an opthomologist for "ocular migraines". The 150mg helped until around Dec. '06 and the migraines and eye issues came back. I am wondering if some of my problems are the Topamax?
