Study Summary
The purpose of this study is to determine the effectiveness of home-based computer therapy for symptomatic convergence insufficiency (CI) compared to traditional home-based near target push-ups and placebo treatment.
Primary Outcome
Pairwise treatment group comparison (HB-C versus HB-PU) of the percentages of participants meeting success criteria using binomial regression adjusting for baseline covariates of CISS score (\<28 points vs ≥ 28 points), mean NPC break (\<10 cm vs ≥ 10 cm), and mean PFV blur (≥ 15 PD vs \<15 PD) using linear contrasts with Bonferroni adjustment for multiple comparisons (Type I error rate = 2.5%). Overall success was defined as meeting all of the following criteria at 12 weeks: 1. Convergence In
Interventions
- OTHER Active home-based computer vergence/accommodative therapy
- PROCEDURE Near target push-ups
- OTHER Placebo home-based computer vergence/accommodative therapy
- PROCEDURE Placebo yoked prism flippers
