PURPOSE: To investigate the prevalence of superior segmental optic nerve hypoplasia in Korea. METHODS: We reviewed the fundus photographs of 3905 individuals who were 40 years old or older and who participated in the comprehensive medical examination program at the Health Promotion Center of Seoul National University Bundang Hospital from March 2003 to December 2006. A single glaucoma specialist reviewed all the photographs, and special attention was paid to the presence of superior segmental optic nerve hypoplasia. The reviewer was masked to information other than the fundus photographs. RESULTS: Superior segmental optic nerve hypoplasia was detected in three eyes of three subjects, which was 0.08% of the 3905 subjects. All three eyes showed a corresponding visual field defect. CONCLUSION: Superior segmental optic nerve hypoplasia might be a rare condition in Korea.
