[Effects of repeated courses of electrostimulation and psychophysiologic correction on visual system characteristics in patients with poor vision of different genesis].

The effect of 5 courses of transcutaneous electrostimulation and of a combination of electrostimulation and psychophysiological correction of vision on the visual functions is assessed in 47 patients (90 eyes) with poor sigh of different genesis. Courses of 8-10-days were administered twice a year for 2.5-3 years. Cluster analysis of 13 objective and subjective parameters of vision permitted singling out patients responding to treatment well and poorly (groups 1 and 2). The absolute and differential electric activities of the central retina were increased during and between the courses in the first group while in the second group the shifts in the retina were negligible. Retinal changes are believed to reflect the general processes of adjustment of its activity to the levels needed for maintaining the integral visual functions, increased during treatment.
