Effectiveness of Vision Therapy in Managing Convergence Insufficiency and Accommodative Dysfunction: A Comprehensive Review

Abstract

Convergence insufficiency (CI) and accommodative dysfunction are prevalent binocular vision disorders that can impact both children and adults, often resulting in significant discomfort during near vision tasks. This review aggregates findings from clinical trials, systematic reviews, and neuroimaging studies to assess the effectiveness of various vision therapy protocols in treating these conditions. Most of the evidence supports office-based vision therapy, typically combined with home exercises, as the most beneficial method for enhancing clinical outcomes and alleviating symptoms associated with CI. However, the role of home-based therapies and their effectiveness in addressing other binocular and accommodative disorders remains uncertain. The review concludes with recommendations for clinical applications and future research directions.
