The effect of low hypermetropia correction and office-based orthoptic training on binocular vision parameters in children with convergence insufficiency.

Purpose: To determine the effect of low hypermetropia correction and orthoptic exercises on binocular visual function in children with symptomatic convergence insufficiency.

Methods: This was a prospective, randomized intervention with a 3-month follow-up. Consecutive pediatric patients with convergence insufficiency and hypermetropia who met inclusion criteria were randomly assigned to one of three treatment groups: spectacle correction and orthoptic training (group 1), spectacle correction alone (group 2) and orthoptic training alone (group 3).
