Home-based perceptual learning augments high-frequency contrast sensitivity and stereopsis after esotropia surgery: A retrospective cohort study

This study demonstrates, for the first time, that home-based PL selectively enhances medium-to-high-SF contrast sensitivity and promotes stereopsis recovery in pediatric esotropia after surgical alignment. These gains, likely mediated by cortical plasticity, address deficits unmitigated by surgery alone. PL represents a scalable adjuvant therapy to optimize functional vision, advocating for its integration into post-surgical rehabilitation protocols.
