ERG of the probands from the two families. a Rod cell response in dark ERG of the proband from family 1. b Cone cell response in light ERG of the proband from family 1. a and b indicated that the amplitude of rod and cone system were reduced, the patient had impaired retinal function in both eyes. c Rod cell response in dark ERG of the proband from family 2. d Cone cell response in light ERG of the proband from family 2. c and d indicated that the amplitude of rod and cone system were severely reduced, the patient had severe impaired retinal function in both eyes
