Summary of light-damage susceptibility in mouse strains used in this study. All mice were exposed to BLE at 12.5 klux light for 0.5 hours, and ONL thickness was determined from OCT images 7 days after BLE (Gnat2−/−, n = 3; Gnat1+/+, n = 13; Gnat1−/−, n = 8; BALB/c, n = 8; Arr1−/−, n = 8; Grk1−/−, n = 6). The retinas were processed as flat mounts 8 days from BLE and stained against opsin antibodies. Cone-area preservation was evaluated from panoramic retina images (Gnat2−/−, n = 3; Gnat1+/+, n = 7; Gnat1−/−, n = 4; BALB/c, n = 9; Arr1−/−, n = 7; Grk1−/−, n = 7). One-sample t-test was used to test if ONL thickness or preserved cone area was significantly different from 100% (baseline). Significance denoted by *P < 0.05, **P < 0.01, *P < 0.001.
