Comparison of the intensity-response the OCT ISez and OS band, with the a- and c-wave of the ERG responses. (A) Example of ERG traces elicited by a light step stimulation. Intensities of light stimulation are shown on the left side panel. (B) Intensity-response relations for ERG a- and c-waves and OCT ISez and OS bands. The data were normalized to their respective peak amplitudes. Continuous cures are fitting to a Naka–Ruston equation (OCT responses: n = 6; ERG responses, n = 5).
