I/R injury impaired retinal function. Using electroretinography (ERG), the a- and b- wave amplitudes were measured from injured contralateral control eyes and I/R-injured eyes (n = 9 mice per group) under a series of light intensities (-30, -20, -10, 0, 5, 10, 15 dB) at 5 time points (7, 14, 21, 28 and 35 days) after I/R injury. Data represent mean ± standard error of a- or b-wave amplitudes (micro voltage) at each light intensity from both control and I/R eyes. Two-way ANOVA (analysis of variance) was applied with the Bonfferoni post-hoc test for statistical analysis. Asterisks indicate statistical differences (p < 0.05) between control and I/R eyes at each light intensity.
