I was taking Topamax for Cluster Headaches for about a week and an half. I woke up one morning and my eyes were very dry, red and etchy. That was around 6:30 am, by 10:30 am my eyes were almost swollen shut. I went to my family doctor and he set me to an eye doctor right then. The eye doctor said it was the Topamax and gave me eye drops and told me to stop using the Topamax. I went from 20/20 to not seeing the big E on the eye chart over night. The area around my eyes became swollen and stayed that way for 5 days before I could even began to see almost anything at all. I was freaking out because I thought I would not be able to see again. After almost two weeks my vision came back almost as well as before taking the med's. It is now around three and a half weeks after stopping taking it and my night vision is still not very good. I still have dry eyes and if I drive at night for very long my eyes get very red and hurt for the rest of the night. I would tell you to be Very careful about taking Topamax. Has anyone else had these kinds of problems with Topamax?

Yes, it's known to cause eye problems. Specifically, glaucoma.

Copypasta'd from wiki.

"Acute myopia and secondary angle closure glaucoma, in a small subset of patients who take topiramate regularly, may cause transient (reversible), or permanent, loss of vision. The symptoms, which typically begin in the first month of use, include blurred vision and eye pain. If addressed early in its course, discontinuation of topiramate, along with other measures deemed prudent by the prescribing physician and/or ophthalmologist, may halt the progression of the ocular damage, and may reverse the visual impairment. Patients who take topiramate and who feel pain in or around their eyes, or notice a loss of vision, visual acuity, or blurred vision, are advised to seek consultation with their physician as soon as reasonably possible. According to the FDA: "in more than 825,000 patients...As of August 17, 2001 there have been 23 reported cases: 22 in adults and 1 in pediatric patients. It is generally recognized that postmarketing data are subject to substantial under-reporting."

Here's the funny thing...it's used to treat something that can cause blindness. Odd isn't it? I myself once had my superior vision disapear for 6 months, the doctors had no clue if I'd get it back. In fact, they didn't think I would.

Poof. 6 months later I wound up with it all coming back, with everyone in neurology and opthamology shocked. I'm sure your vision will get completely back to normal too. Your eyes probably just need time to recover from the trauma!
