Objectives To evaluate the prevalence of cupping in arteritic anterior ischemic optic neuropathy (AAION) and nonarteritic anterior ischemic optic neuropathy (NAION). Design: Retrospective, observational case series. Participants: Three hundred one patients. Methods: Review of clinical records and color fundus photographs. Main Outcome Measures: Photographic and clinical interpretation of optic nerve appearance. Results: Ninety-two patients with AAION and 102 with NAION were included in the study, Disc photographs of 42 patients (48%) with AAION and 32 patients (31 %) with NAION were available for reassessment. These were presented in a masked fashion along with a random sample of 27 disc pairs considered to be 'normal' and 27 disc pairs with 'established glaucoma' according to two examiners. Cupping was present in 92% of eyes with AAION secondary to giant cell arteritis and in 2% of eyes with NAION (kappa = 0.96; P < 0.001). Conclusions: The end-stage optic disc appearance in AAION secondary to giant cell arteritis is cupping, whereas segmental or diffuse pallor without cupping is the typical disc appearance after NAION.
