Figure 5. Functional and behavioral benefits of the RS1 therapy. A: The mean b-/a-wave ratio from the scotopic electroretinogram (ERG) were compared between treatment groups at 2, 4, and 8 weeks post-injection. B: The spatial frequency threshold was measured and compared between the groups at 2, 4 and 8 weeks post–injection. All data are presented as mean ± standard error of the mean (SEM; p<0.05, n=6).
