RESUMEN
A variety of subthreshold laser methods that enable selective and precise treatment of chorioretinal microstructures, thus decreasing the risk of negative changes in retina and choriocapillaries, is used in current ophthalmological practice. This comparative pathomorphological and histochemical study allowed characterizing structural changes and functional activity of chorioretinal cells after application of different subthreshold laser technologies.

The influence of several subthreshold laser procedures on chorioretinal complex (CRC) tissues was experimentally studied in rabbits using histological and histochemical methods. Subthreshold micropulse laser radiation and transpupillar thermotherapy were found to have the most attenuated and advantageous effect on CRC structure. The feature of subthreshold laser exposure is partly reversible selective changes in CRC, that have temporary stimulating effect on cellular metabolism and local regenerative processes providing an opportunity for still viable tissues to function adequately.
