Fig. 2

a Dark-adapted responses in an IAA-treated minipig before and 1 month after IAA administration and in an untreated minipig at matching time points. The dashed lines indicate the flash onset. The quantification of the a-wave and b-wave is indicated. b, c Quantification of the dark-adapted fERGs in IAA-treated (mean ± s.d., n = 10 eyes from N = 5 minipigs) and untreated (mean ± s.d., n = 4 eyes from N = 2 minipigs) animals. Grey lines are the logistic growth regressions for IAA-treated (a-wave before: R2 = 0.6973; a-wave after: R2 = 0.0975; b-wave before: R2 = 0.3972; b-wave after: R2 = 0.0723) and untreated (a-wave before: R2 = 0.5283; a-wave after: R2 = 0.5368; b-wave before: R2 = 0.7283; b-wave after: R2 = 0.6258) minipigs. Extra sum-of-squares F test; IAA-treated: p < 0.0001 (****) for both a-wave and b-wave; untreated: p = 0.0355 (*) for a-wave and p = 0.3235 (n.s.) for b-wave. d Light-adapted responses in an IAA-treated minipig before and 1 month after IAA administration and in an untreated minipig at matching time points. The dashed lines indicate the onset of the flash. e, f Quantification of the light-adapted fERGs in IAA-treated (mean ± s.d., n = 10 eyes from N = 5 minipigs) and untreated (mean ± s.d., n = 4 eyes from N = 2 minipigs) animals. Two-tailed paired t-test; IAA-treated: p < 0.0001 (****) and power 1.00 for both a-wave and b-wave; untreated: p = 0.0463 (*) and power 0.97 for a-wave and p = 0.4043 (n.s.) and power 0.71 for b-wave. g Quantification of the light-adapted fERGs in IAA-treated (n = 7 eyes from N = 5 minipigs) and untreated (n = 4 eyes from N = 2 minipigs) minipigs over time. IAA was administered on day 0 after the recordings. Data in panels a, d are from MP4 (IAA-treated) and MP1 (untreated). Data in panels b, c, eg are from MP4–8 (IAA-treated) and MP1–2 (untreated).
