Hydrogen gas attenuated BRVO rat retinal oedema and protected the retinal structure integral. a: Typical fundus photograph and OCT pictures at 1, 3, 5, 7, 14 and 30 d post-occlusion; b: Thickness of total retina of each group at 1, 3, 5, 7, 14 and 30 d post-occlusion; c: Thickness of the ONL of each group at 1 d, 3 d, 5 d, 7 d, 14 d and 30 d post-occlusion; d: Thickness of the INL of each group at 1, 3, 5, 7, 14 and 30 d post-occlusion; e: Thickness of IPL + GCL + NFL of each group at 1, 3, 5, 7, 14 and 30 d post-occlusion. All analyses were performed in duplicate. The data are expressed as the mean ± standard deviation (SD), n = 4–12 rats per group. ^*, p < 0.05, H and M group vs C group; ^#, p < 0.05, H group vs M group. a: fundus photograph; b: fluorescent fundus colour photography. C: control group, M: model group, H: hydrogen gas group
