Oguchi’s disease with Mizuo-Nakamura phenomenon in a seven-year-old boy

Abstract

A seven-year-old boy presented with difficulty in night vision of five years duration. Vision was 20/20 OU. Fundus examination revealed a golden sheen over the posterior pole in both eyes which disappeared after 45 minutes of dark adaptation, suggestive of Mizuo-Nakamura phenomenon. Clinical findings were suggestive of Oguchi’s disease. ERG was confirmatory.
