Antioxidant potential of tear fluid and blood plasma in rabbits with grade III chemical eye burn at various stages of burn disease

The antioxidant potential of tear fluid and plasma in rabbits with chemical eye burn of grade III was measured at various stages of burn disease. Eye burns were accompanied by depletion of the antioxidant system in tear fluid and plasma and impairment of antioxidant defense in the whole organism. These changes contribute to activation of free radical lipid peroxidation. The pathological changes in the organism and eye were most pronounced at the stage of trophic disturbances.
