We herein describe a case of a patient whose only symptom was nyctalopia. Peculiar ophthalmoscopic findings of Oguchi's disease were observed. Classic changes in the electroretinogram (ERG) and Mizuo-Nakamura's phenomenon were also reported. To the best of our knowledge, there isn't another occurrence in our published literature. A brief bibliographic review is added.
