Figure 3
A plot of the average amplitudes of each ERG component for Groups 1 to 4 of the 17 eyes with FEVR.
The red upper and lower lines represent the 5 and 95 percentiles obtained from the 44 normal control, respectively. The amplitudes of all ERG components are significantly decreased as the degree of the Rdrag and Rfolds progresses (Groups 1–4, P < 0.01).
