Oguchi disease is a rare autosomal recessive form of congenital stationary night blindness in which all other visual functions, including visual acuity, visual field, and color vision, are usually normal. A typical feature of the disease is a golden or gray-white discoloration of the fundus that disappears in the dark-adapted state and reappears shortly after the onset of light (Mizuo phenomenon, or Mizuo-Nakamura phenomenon). The course of dark adaptation of rod photoreceptors is extremely retarded, whereas that of cones appears to proceed normally.
