To determine if improvement of vision may be achieved even beyond the time window of spontaneous recovery, two prospective, randomized, placebo-controlled clinical trials were conducted with 38 patients who sustained visual system injury.

The study demonstrated that computer-based visual restitution training can significantly enlarge the visual field after damage (Kasten et al., 1998c).

The patients were assigned to an experimental group (treated with restitution training) and a placebo group (provided with foveal fixation training only).

Most patients in the placebo group experienced no change in visual field size, while the experimental group displayed a reliable visual field enlargement as revealed by a significant shift of the visual field border and by improvements in the detection of small visual stimuli (Kasten et al., 1998c).
