The scotopic a- and b-wave amplitudes of the NFE2L2 KO control mice were substantially smaller than those of the WT treated and control groups (dashed red and black lines in Figures 1(a)–1(d); p < 0.001 for each group), suggesting accelerated retinal degeneration in the NFE2L2 KO mice compared to the WT mice. This evidence concerns the gene NFE2L2 and retinal degeneration.
