[Topiramate and acute myopia with angle-closure glaucoma: case report and literature review]. / Topiramate et myopie avec crise aiguë de fermeture de l'angle irido-cornéen: cas clinique et revue de la littérature.

ABSTRACT

Topiramate, an antiepileptic medication, has been widely used since its recent indication for migraine prophylaxis. We report a case of bilateral angle-closure glaucoma and acute myopia in a 44-year-old woman on oral topiramate therapy initiation for migraine prophylaxis. Intraocular pressure was 31 mmHg right and 32 mmHg left, myopia was 4 diopters. Topiramate was interrupted and general and local hypotensive treatment begun and rapidly stopped after improvement. Iridotomy was also performed. Fifteen days later, complete resolution was observed on ophthalmologic examination anterior chambers were deep, myopia fully regressed, intraocular pressure returned to normal, and the visual field was complete. This new case prompts discussion on current reports in the literature and French drug monitoring database cases in this context.
