[Effect of UV-B radiation on the parameters of rabbit electroretinogram]

Rabbit's eyes were exposed to UV-B-light (lambda = 280-320 nm) at biologically effective doses of 20 to 1300 J/M2. The amplitudes of a- and b-waves of the ERG were found to decrease during a period of 7-20 days to reach approximately 50% of the initial level at a maximum dose. By day 30 the wave amplitudes returned to the control. The latencies of both ERG waves were invariable throughout the entire period of observation. The postirradiation changes in the ERG wave amplitudes were most pronounced during the attenuating photokeratitis.
