Biofeedback training

Biofeedback training: This 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.

Study summary

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.

Healthy volunteers

Inclusion Criteria: Hemianopia cases with more than 6 months from the date of the lesion, previously diagnosed accordingly by micro perimetry and other tests as needed, 18-90 years old, ability to follow the visual and auditory stimuli and training instructions. Exclusion Criteria: Previous or current treatment for low vision rehabilitation, ocular diseases, other serious clinical conditions not related to the hemianopia, both eyes with media opacity that impairs microperimetry testing, lack of ability to perform the tests and training.

Primary outcome measure(s)
