  • Title: ERG characteristics of congenital stationary night blindness.
    Author: Wu D, Xu X, Wu L, Luo T.
    Journal: Yan Ke Xue Bao; 1990 Jun; 6(1-2):32-5. PubMed ID: 2101357.
    Abstract:
    The ERGs of 9 cases (18 eyes) of congenital stationary night blindness with normal fundi or myopia were tested. All eyes showed nonrecordable rod ERG and cone ERG with normal a-wave. Scotopic mixed ERGs were of the negative type in 7 eyes and of the subnormal type in 11 eyes. The b/a ratio was reduced in all eyes. The ERG characteristics are useful for the classification, estimation of the probable location of the lesion, and differential diagnosis of the disease.
