Lipid peroxidation and retinal degeneration

Abstract
Retinal degenerations were produced in albino rats by exposure to constant illumination or in frogs and albino rats by intravitreal injections of ferrous sulfate. Both treatments resulted in the loss of long-chain polyunsaturated fatty acids and the accumulation of lipid hydroperoxides in isolated rod outer segments. We suggest that lipid peroxidation is a factor in certain types of retinal degenerations.
