Figure 6. Changes in the electroretinogram responses after light exposure. Electroretinographic (ERG) responses recorded from the left eyes of control animals before light exposure (red lines) and experimental animals 1, 3, 7, 30, or 180 days after light exposure (ALE; black lines). The three first rows correspond with the scotopic threshold response (STR) waves, while the rest correspond with the a- and b-waves. For convenience, the responses recorded in control animals before light exposure have been superimposed over the responses recorded in experimental animals. For details on control animals, see text.
