Biofeedback training for improving vision in patients with hemianopia
Official title: Biofeedback Training to Improve Fixation Stability, Visual Function Outcomes, and Quality of Life in Hemianopia Cases
Run by University Health Network, Toronto · NCT05397873 · Data updated 2026-11-12
This study tests if biofeedback training can help people with vision loss from brain injuries learn to see better by improving how they move their eyes and focus on things.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are adults aged 18-90 with diagnosed hemianopia who can follow visual and auditory training instructions.
✕Probably not a fit
Patients with other serious clinical conditions, ocular diseases, or those who have previously undergone low vision rehabilitation may not benefit from this study.

What this trial studies
This study focuses on patients suffering from homonymous hemianopia due to brain injuries such as stroke, surgery, or trauma. It employs biofeedback training to enhance oculomotor control, helping patients learn to shift their visual attention into their blind visual field. By using advanced microperimetry instruments, the training aims to improve visual processing and eye movement control, which are crucial for daily activities like reading. The study seeks to fill the gap in rehabilitation programs for visual field loss, which is often overlooked in clinical settings.
Why it matters
Potential benefit: If successful, this approach could significantly improve the quality of life for patients with hemianopia by enhancing their visual capabilities and independence.
How similar studies have gone: While biofeedback training is a newer approach, previous studies have shown promise in improving visual function in similar patient populations.
