영문 초록

The purpose of this article is to report a case of nonarteritic anterior ischemic optic neuropathy (NAION) after uneventful cataract surgery. A 53–year-old Filipina underwent cataract surgery. She had a small optic disc with cup-to-disc ratio of 0.2 in the left eye and 0.3 in the right eye. On the first postoperative day, the uncorrected visual acuity (UCVA) was 20/20, with an intraocular pressure (IOP) of 20 mmHg in the left eye. At one week after operation, the UCVA was 20/20 and the IOP was 15 mmHg. Three weeks later, she underwent cataract surgery in the right eye. On the first postoperative day, her UCVA was 20/20 in both eyes, but she complained of a visual field decrease n the left eye. A relative afferent pupillary defect (RAPD) was noted and the optic disc was pallid and swollen diffusely. A red-free photo showed defect surrounding the optic disc. A visual field test showed tunnel vision sparing the central vision. In this report, the authors hypothesize an association between cataract extraction and delayed NAION. Since the risk of NAION in the fellow eye is 30-50%, visual acuity, visual field, fundus exam and RAPD should be routinely checked.
