Figure 1. Dark-adapted electroretinograms

A: Comparison of dark-adapted ERGs recorded from control and affected rats. B: Amplitude of dark-adapted a-wave (square) and b-wave (circle) for control (filled) and affected rats (open). Data points indicate the mean±SEM. response from ten 10-week-old rats. C: Peak time of dark-adapted a-wave (square) and b-wave (circle) for control (filled) and affected rats (open). Data points indicate the meanpom SEM. response from ten 10-week-old rats.
