Personalized Rehabilitation for Residual Deficits: Tailoring Perceptual Learning for Improved Visual Function in Meridional Amblyopia.

ABSTRACT:

Purpose

This study explored the efficacy and predictors of success for a novel monocular fine orientation discrimination perceptual learning (fine-PL) approach in addressing perceptual deficits in meridional amblyopia (MA).

Design

Prospective, longitudinal study.

Participants

Fifty-three children with persistent MA participated in this study.

Methods

Twenty-one participants underwent a 14-day regimen of monocular fine-PL focused on grating orientation discrimination exercise (±5°) aligned with the vertical or horizontal meridian near each individual's threshold spatial frequencies. Nineteen participants underwent coarse orientation discrimination perceptual learning (coarse-PL), and 13 participants received optical correction alone.
