Biofeedback Training for Hemianopia

Biofeedback Training to Improve Fixation Stability, Visual Function Outcomes, and Quality of Life in Hemianopia Cases

Sponsor

University Health Network, Toronto

Enrollment

70 participants

Start Date

Dec 8, 2021

Study Type

INTERVENTIONAL

Conditions

Hemianopia Brain Injuries

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.

Plain Language Summary

Simplified for easier understanding

This study tests biofeedback training to help people with hemianopia — a condition where half the field of vision is lost, usually after a stroke or brain injury — learn to better use their remaining vision and improve visual awareness. **You may be eligible if...** - You have been diagnosed with hemianopia for more than 6 months - Your hemianopia has been confirmed by specialized vision testing (microperimetry) - You are between 18 and 90 years old - You are able to follow visual and sound-based instructions and training **You may NOT be eligible if...** - You are currently receiving or have previously received low vision rehabilitation treatment - You have other eye diseases affecting your vision - You have serious health conditions unrelated to hemianopia that could interfere - You have cloudiness in both eyes that prevents accurate vision testing Talk to your doctor to see if this trial is right for you.

Interventions

BEHAVIORALBiofeedback 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.
