Normal S cone electroretinogram b-wave in Oguchi's disease

Abstract

These ERG results indicate that the S cone system as well as the L and M cone system is not defective in Oguchi's disease, while the S cone responses are not detectable in the complete type of congenital stationary night blindness as reported previously. The results imply that there is a significant difference in the way the S cone system is affected in different forms of stationary night blindness, and that the S cone and rod do not share the same arrestin system.
