CSNB type 1 (CSNB1) CSNB type 2 (CSNB2) CSNB autosomal dominant (CSNBAD) Oguchi disease/ CSNB Oguchi type (CSNBO)
Description
Congenital stationary night blindness (CSNB) is a group of nonprogressive retinal disorders characterized by impaired night vision. CSNB is currently associated with X-linked genes (NYX, CACNA1F), autosomal recessive genes (CABP4, GRK1, GRM6, SAG, TRPM1), and autosomal dominant genes (GNAT1, PDE6B, RHO). Two types of CSNB can be distinguished by use of the standard flash electroretinogram (ERG). CSNB type 1 (CSNB1) is characterized by the complete absence of rod pathway function, whereas CSNB type 2 (CSNB2) is caused by impaired rod and cone pathway function. Oguchi disease is a form of CSNB. Patients with the Oguchi disease have a unique yellowish-gold fundus that regains its normal color after prolonged dark adaptation. That is called the Mizuo-Nakamura phenomenon.
