Schematic of the oxidative-stress induced model. Wildtype mice at age 3 weeks (weaning age) were placed on the grape-supplemented or sugar control diet. After 5 weeks, the mice were placed randomly into two study groups, the paraquat (PQ)-injected group and the saline control group. The mice were maintained on the diet until the retina phenotype was analyzed after an additional 2 weeks.
