The Electroretinogram (ERG) is a composite signal reflecting the complex response of the retinal different parts. It is known that the rod and cone systems contribute to this response. The most used method to analyze the data is the study of the b-wave amplitude and peak time change against the intensity of the stimulus theoretically investigated by an approach based on a simplified picture of a single responding photoreceptorial population in scotopic or photopic condition. The aim of the present paper is to investigate the dependence of the amplitude and the implicit time of the a- and b-wave of the ERG on the input luminance level to obtain hints devoted to recognize the different contribution to the response of the two systems, rods and cones, in normals and pathological subjects. © 2000 American Institute of Physics.
