[Severe ocular side effects with Topamax].

CASE REPORTS: We describe 2 patients who developed ocular side effects during treatment with topiramate. One was a 16-year-old woman with generalized seizures who developed a homonymous hemianopia after using topiramate 125 mg per day for 12 weeks, and the other was a 24-year-old epileptic female who developed a bilateral maculopathy after using topiramate 150 mg per day for 8 weeks. DISCUSSION: We identified two severe ocular adverse reactions from topiramate. Both reactions necessitated discontinuing the treatment, but the topiramate-associated maculopathy was irreversible.
