Non-arteritic anterior ischemic optic neuropathy secondary to acute primary-angle closure
Kuriyan AE; Lam BLClinical Ophthalmology 2013; 7: 1233-1238
PURPOSE: To describe a case of non-arteritic ischemic optic neuropathy (NAION) secondary to acute primary-angle closure (APAC). METHODS: Case report. RESULTS: A 50-year-old woman with painful visual loss in the right eye was found to be in APAC with a right afferent pupillary defect. Laser peripheral iridotomy relieved pain but did not improve vision. Diffuse optic disc edema in the right eye and a small cup-to-disc ratio in the left eye were evident. Magnetic resonance imaging was normal. The patient was diagnosed with non-arteritic ischemic optic neuropathy (NAION) secondary to APAC, a rare clinical entity which can result in markedly decreased visual acuity. CONCLUSION: NAION secondary to APAC is a rare clinical entity that can result in severe vision loss.
