Figure 4.

Photopic and scotopic light responses of 2.5-month - old lgals3^−/− mice are normal. (A) Bars show quantification of maximal photopic ERG a- and b-wave amplitudes, as indicated. Gray bars, wt mice; black bars, lgals3^−/− mice; mean ± s. e. m., n = 8; Student's t-test; p > 0.05; n. s., not significantly different. (B) Dot plots show quantification of maximal scotopic ERG a- and b-wave amplitudes recorded with increasing white light flash intensities as indicated. Open circles, wt mice; black circles, lgals3^−/− mice. Lines indicate averages ± s. e. m., n = 9. No significant differences between wt and lgals3^−/− mice were found by 2-way ANOVA regardless of light intensity.
