Vision restoration therapy (VRT) after brain damage: retrospective analysis of visual fields in 300 patients and eye movement recordings

Objective: Restoration of visual field defects have long been considered impossible. However, visual plasticity can be induced by a computer-based training program, „Vision Restoration Therapy (VRT)“. We now wished to determine the role of eye movements in this process and analyzed retrospectively the effects of VRT in a 300 patient sample. Background: VRT stimulates areas of residual vision („relative defects“) during daily training for a 6 months period which results in visual field enlargements as shown perimetrically. We now replicated our earlier findings with a larger patient population and in a separate p…
