Attention-based Binocular Training for Impaired Stereopsis (BRAVE)

This study evaluates a novel attention‐based binocular visual search training paradigmdesigned to improve stereopsis (stereo vision) in individuals with impaired binocularvision. Disruptions in balanced binocular input, such as from strabismus oranisometropia, often lead to deficient stereo vision, causing daily visuomotorlimitations. While traditional therapies focus on monocular acuity, they frequently failto restore stereopsis, especially in adults. The investigators propose a unique dichopticvisual search training method that embeds binocular disparity inside anattention‐demanding task, encouraging cooperative binocular integration. Participantsaged 18‐39 with impaired stereopsis will be randomly assigned in a 1:1 ratio to eitherthe active training group (disparity‐embeded task) or the active control group (identicaltask with zero disparity). Both groups complete 5 training sessions over 5‐6 weeks.Assessments will occur at baseline, immediately post‐training, and at a 12‐weekfollow‐up. The primary objective is to determine if the active training group showssignificantly greater improvements in local stereoacuity compared to the control group.
