EEG neurofeedback to restore vision after stroke
Official title: Neurofeedback-based Visual Restoration Therapy
Run by University Hospital, Geneva · NCT07237412 · Data updated 2026-11-12
This project will test whether EEG neurofeedback can help people aged 50–70 with chronic homonymous visual field defects after a stroke improve their visual field and everyday vision.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are adults aged 50–70 with stable homonymous visual field defects at least 12 months after a stroke who can give informed consent and tolerate long training sessions.
✕Probably not a fit
Patients with active eye disease affecting the field or acuity, hemispatial neglect, recent stroke, non-MRI-safe metal in the body, or an inability to concentrate for long sessions are unlikely to benefit from this intervention.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
This interventional study uses EEG-based neurofeedback to teach patients to increase communication between brain regions that support visual processing. Participants who are at least 12 months post-stroke and have stable homonymous visual field defects will undergo repeated neurofeedback training sessions designed to shift brain network states before visual tasks. Visual field measurements and functional vision tests will be used to track any changes over the course of the intervention. The trial excludes people with progressive eye disease, hemispatial neglect, or inability to tolerate long sessions.
Why it matters
Potential benefit: If successful, the approach could enlarge or improve patients' visual fields and make reading, mobility, and daily tasks easier.
How similar studies have gone: Prior neurofeedback studies have shown promise in improving post-stroke motor network coordination and mobility, but applying EEG neurofeedback specifically to restore visual fields is relatively novel and not yet proven.
