Bilateral sequential NAION following cataract extraction: Case report and review of the literature

Abstract

We report a 64-year-old patient who developed nonarteritic ischemic optic neuropathy (NAION) in both eyes following cataract extraction. The cataract surgeries in both eyes were uneventful and performed within a year, and NAION occurred a few months postoperatively in both eyes. A review of the literature on this rare complication is provided. This case report serves to raise awareness among cataract surgeons about this potential complication associated with irreversible visual loss, and especially about its high risk of bilaterality.
