Antioxidants protect retinas from degeneration and reduced function in Vldlr–/– retinas.

(A and B) In retinas of antioxidant-treated 2-mo-old Vldlr–/– mice, decreased acrolein staining was observed compared with age-matched vehicle-treated controls. Panels in A are composite montages of multiple serial micrographs. Error bars denote SEM. NT, not treated; Anti, antioxidant treatment. (CG) Vldlr–/– mice were subjected to a 6-wk treatment with vehicle or antioxidants, beginning at 2 mo of age. (C) Antioxidant treatment attenuated the loss of cones and rods, as demonstrated by normalized expression of opsin-1 and rhodopsin, respectively. n = 12 retinas per group. Error bars denote SEM. (D and E) The extent of subretinal NV in 3.5-mo-old Vldlr–/– mouse retinas was not affected by antioxidant treatment. n = 12 retinas per group. Error bars denote SEM. (F and G) ERGs were normalized after 6 wk of antioxidant treatment. Note decreased and delayed signaling in vehicle-treated Vldlr–/– mice compared with those treated with antioxidants. Scale bars: 250 μm.
