[Effect of low-intensity impulse diffuse laser radiation on the functional state of the visual analyzer].
Studies were performed on rabbits to investigate single stimulation of the rabbit's eye with low-intensive dissipated laser radiation at 0.53 micron and their influence on the bioelectric activity of the retina which was evaluated at the amplitude b-ERG wave. Established was the dependence of the stimulus' disadapting effect on the laser radiation density within the range of 1 x 10(-11)-3.5 x 10(-4) J.cm-2. The radiation beams with at frequency of 50 Hz and density of 1 x 10-11 J.cm-2 or less did not exhibit any disadapting effect on the retina. Radiation density at 1 x 10(-9)-1 x 10(-7) J.cm-2 decreased the b-ERG wave amplitude only at the time of stimulating the retina. This biological effect can be regarded as an adequate physiological reaction to the stimuli. Radiation exposition at 1 x 10(-6)-4 x 10(-4) J x cm-2 caused a decrease in b-ERG wave after the retina had been stimulated.
