Congenital nystagmus
Gene: SAG
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.
Well established gene-disease association, multiple families reported. Nystagmus is not a feature.Created: 5 May 2021, 10:51 a.m. | Last Modified: 27 Oct 2021, 6:04 a.m.
