Effects of ultraviolet radiation.

Abstract

Ultraviolet radiation from high-intensity sources has well-known acute effects on the eye and skin, consisting primarily of photokeratoconjunctivitis and sunburn, which are enhanced in the presence of photosensitizing agents. Long-term elevated exposure to low-level ultraviolet radiation is also responsible for an increased risk of squamous- and basal-cell carcinomas; probably responsible for an increased risk of cortical and posterior subcapsular cataracts, pterygium, and cutaneous melanoma and intraocular melanoma and possibly responsible for immunologic effects of clinical significance.
