Congenital Stationary Night Blindness with Myopia

PURPOSE: To report a case of Congenital stationary night blindness associated with myopia. METHODS: A 19-year-old male with night blindness was referred to our hospital. We studied patient's family history, refraction, color vision test, fundus examination, electroretinogram and visual field. RESULTS: Both fundi showed temporal conus and myopic change. Both visual field revealed generalized depression. The light- and dark-adapted electroretinogram showed a normal a wave with extremely reduced b wave, resulting in a typical "negative" wave form.
