Our preliminary research using high-speed eye tracking demonstrated that people with larger scotomas have impaired eye movement control, and that single-session visual feedback training showed limited immediate benefit, though combining feedback types showed promise.\n\nThis study will evaluate whether extended binocular training (5 weekly sessions) with multimodal feedback improves eye movement control in 8-15 participants with bilateral central vision loss. Unlike conventional monocular rehabilitation systems, our approach trains both eyes simultaneously using real-time visual and auditory feedback during saccadic and smooth pursuit tasks. Participants will receive gaze-contingent scotoma awareness feedback, preferred retinal locus feedback, and auditory cues while performing eye tracking exercises.\n\nPrimary outcomes include saccadic accuracy (latency, landing error, amplitude) and smooth pursuit parameters (gain, tracking accuracy). Secondary outcomes include contrast sensitivity and self-reported visual function.
