Relationship between serum reactive oxidative metabolite level and skin reaction in an irradiated rat model.

abstract：:Although the primary biological function of retinal photoreceptors is to absorb light and provide visual information, extensive exposure to intense light could increase the risk of phototoxic reactions mediated by products of rhodopsin bleaching that might accumulate in photoreceptor outer segments (POS). The phototox...
