An autosomal recessive, non-progressive retinal disorder characterized by impaired night vision, absence of the electroretinogram (ERG) b-wave, and variable degrees of involvement of other visual functions. Affected individuals have an ERG waveform that lacks the b-wave because of failure to transmit the photoreceptor signal through the retinal depolarizing bipolar cells.
