Multimodal-feedback vision rehabilitation for people with central vision loss
Vision Rehabilitation Training With Multimodal Feedback in Central Vision Loss
This trial will test whether five weekly sessions of binocular multimodal feedback training can improve eye movement control in people with bilateral central vision loss from macular degeneration.

What this trial studies
The study will enroll 8–15 participants with bilateral central vision loss from macular degeneration who will complete five weekly in-person binocular training sessions using high-speed eye tracking. Training pairs gaze-contingent scotoma awareness feedback and preferred retinal locus feedback with auditory cues while participants perform saccadic and smooth pursuit tasks to retrain peripheral viewing. Outcomes compare eye-movement control and functional performance before and after the training regimen. Participants must meet acuity, cognitive, and hearing criteria and attend sessions at the Boston site.
Who should consider this trial
Good fit: Ideal candidates are age 14 or older with bilateral central scotomas from macular disease, visual acuity between 20/60 and 20/200, stable vision for the past six months, normal cognition, and adequate hearing and English fluency to complete training.
Not a fit: Patients with unstable or actively treated ocular disease, severe peripheral field restriction, other conditions that independently impair oculomotor control, significant hearing loss, or visual acuity outside the specified range are unlikely to benefit.
Why it matters
Potential benefit: If successful, the approach could improve eye movement control and make everyday tasks like reading, face recognition, and navigation easier for people with central vision loss.
How similar studies have performed: Prior pilot work showed limited immediate benefit from single-session feedback but suggested that combining visual and auditory feedback across sessions may produce improved eye-movement control.
