In Kaunas Boarding School for Partially sighted children during 2000/2001 academic year were studying 102 students. All of them were checked by specialists: ophthalmologist, physiotherapist and psychologist. The majority of illnesses were linked with pathology of visual nerve (25,4%).

The students were divided in two groups according to the visual acuity. In the first group there were 9 students who had the visual acuity from the light perception to the 0,1. In the second group there were 17 students who had the visual acuity from 0,1 and more.

The visual field was examined by Goldman’s perimeter. It was deduced different kinds of visual field defects for students in both groups.

Medical rehabilitation was applied: transcutaneous electrostimulation course of the visual nerve twice a year, giving 10 procedures and electrophoresis including vitamins.

Examining the visual field it was founded that the result of two courses of therapy the visual field has improved for 5 students in the first group, and for 17 students in the second group.
