Figure 1. Light exposure abolishes the electroretinographic response. A: Electroretinograms from the left eyes of albino rats (n=12), before light exposure and 1 day and 1 week after light exposure (ALE). B-C: Mean amplitudes (±SE) of the a- and b-waves and scotopic threshold response (STR) before light exposure (open symbols) and 24 h (B) and 1 week (C) ALE (closed symbols). Error bars are shown when larger than symbols.
