About this trial
This is a prospective study that compares biofeedback training on the microperimetry (BT) to a control group in patient s with hemianopia. The patients receive 5 sessions of 20 minutes to stimulate with light and sound the brain in using the best residual area on the visual fields post-brain injury visual loss. Visual tests and quality of life questionnaire are performed pre-and-post-training.

Biofeedback training
BehavioralThis is an audio-luminous stimulation on the micro perimeter that teaches the brain to use a different fixation locus on the retinal other than the fovea and develops visual attention to the surrounding retinal areas. 20 minutes exercises for stimulation are performed on the micro perimeter, once a week, for 5 weeks.
