Alterations in biochemical properties of rabbit aqueous humor (AH) under conditions of LIRD. The animals were illuminated with intense visible light (30,000 lx) for 3 h (the course of the illumination is shown as gray box). AH samples were collected before (norm) and immediately after (3 h) the illumination as well as on 1, 3, and 7 day post-exposure. The samples were analyzed for total protein, tumor necrosis factor alpha (TNF-α), and malondialdehyde content as well as total antioxidant activity (in Trolox equivalent) and activity of glutathione peroxidase and superoxide dismutase using the respective assays. * p < 0.05 as compared to parameters of AH of the intact (control) animals.
