ABSTRACT
PURPOSE:
To report specific spectral domain OCT findings of Oguchi disease diagnosed with fundoscopic examination and electrophysiological study. CASESUMMARY:
A 14-year-old patient visited our clinic with a complaint of night blindness for ten years. Fundoscopic examination showed a golden-yellow fundus reflex. After three hours of dark adaptation, the fundus color returned to normal (Mizuo-Nakamura phenomenon). In full-field ERG, rod b-wave was not detectable. The a-wave amplitude in maximal combined response increased after three hours of dark adaptation, although the b-wave amplitude was similar to the amplitude before dark adaptation, demonstrating a negative waveform. In the spectral domain OCT images of the perifoveal area, no gap between the retinal pigment epithelium and the inner segment/outer segment (IS/OS) junction was detected before prolonged dark adaptation, and a highly reflective band was shown. However, the gap appeared after three hours of dark adaptation, and two highly reflective bands were detected in the OCT images.CONCLUSIONS:
The characteristic OCT finding in addition to the specific fundoscopic finding and full-field ERG results may be useful to diagnose Oguchi disease.
