Abstract

We have studied the influence of laser radiation on eye tissues. It was shown that argon laser radiation induced damages in retina and pigment epithelium. Disorganized segments of photoreceptors, dispersed vesicles were observed in retina after irradiation. The laser irradiation of pigment epithelium leads to fragmentation and dispersion of the membrane material. Changes in the protein composition of membrane proteins of retina were not observed by the method of gel-electrophoresis after laser irradiation. Electrophoresis profiles of pigment epithelium samples shown inessential changes in protein composition. The oxidation of SH-groups does not take place in these both cases either.
