Abstract
The induction of DNA photoproducts in rat corneal epithelium was studi ed after in vivo exposure to different doses of ultraviolet B light at 297 nm. Affinity-purified antibodies with a major specificity against UV-induced (6-4) photoproducts were used. The results indicate a dose dependent formation of (6-4) photoproducts. Even a minimal erythema d ose (25 mJ/cm(2)) produced (6-4) photoproducts, demonstrating that DNA damage occurs in corneal tissue following exposure to biologically re levant doses of UVB light.
