| Summary: | Ajay E Kuriyan, Byron L Lam Bascom Palmer Eye Institute, University of Miami, Miami, FL, USA 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. Keywords: acute angle closure glaucoma, perfusion pressure, NAION, optic nerve |
