Home-based vision therapy for post-concussive near-vision problems
Official title: Home-based Treatment of Binocular Eye Dysfunction in Veterans With Traumatic Brain Injury
Run by VA Office of Research and Development · NCT06886737 · Data updated 2026-11-12
We will test a virtual-reality home training game to help Veterans with convergence insufficiency after concussion improve near vision and reduce double vision.

Is this trial a fit for you?
✓Likely a good fit
U.S. military Veterans with convergence insufficiency after TBI who have good corrected vision (20/25 or better), a recent eye exam, and live within driving distance of Cleveland, Ohio.
✕Probably not a fit
Patients with prior binocular vision problems such as pre-existing strabismus or amblyopia, other neurological conditions affecting convergence, or worse than 20/25 acuity are unlikely to benefit from this intervention.

What this trial studies
This Phase 1 interventional study enrolls U.S. military Veterans with convergence insufficiency to use a virtual-reality convergence training game at home. Participants must have recent clinical eye exams, best-corrected visual acuity of 20/25 or better, and live within driving distance of Cleveland, Ohio. The program combines novel VR-based diagnostic tasks with game-like training exercises aimed at improving near point convergence and binocular coordination. Study staff at the VA will perform baseline and follow-up measurements to track changes in near vision function.
Why it matters
Potential benefit: If successful, the VR home-training could restore near vision function, reduce double vision, and improve reading, work, and daily activities for affected Veterans.
How similar studies have gone: Clinic-based vision therapy has shown benefit for convergence insufficiency in some studies, but home-based virtual-reality approaches are novel and not yet proven.
