TOPIRAMATE-INDUCED ACUTE, BILATERAL MYOPIA IN A MIGRAINE PATIENT

Abdullah O. Almajnoni, Saeed A. Al-Ghamdi

Topiramate is an anticonvulsant drug and is used to prevent migraine headache. We report here an unusual presentation of topiramate-associated adverse effects. A 30-year-old female patient presented with a migraine and no report of eye disease. Ten days after taking topiramate, her visual acuity was suddenly reduced. On examination, she was found to have bilateral acute myopia that was later attributed to topiramate. Therefore, the medication was discontinued. A week later, the visual acuity of the patient returned to normal (6/6) in both eyes, with no other visual complaints. In conclusion, physicians prescribing topiramate should observe their patients for any visual complaints, as this would prevent subsequent permanent visual impairment.
