Recruit Status: Completed
Study Type: Interventional
Official Title: A Randomized Clinical Trial of the Effectiveness of Base-in Prism Reading Glasses Vs. Placebo Reading Glasses for Symptomatic Convergence Insufficiency in Children
Brief Summary: This study is designed to compare the use of special prism glasses to placebo treatment for children with symptomatic convergence insufficiency.
Detailed Summary:
The Base-in for Convergence Insufficiency Treatment Trial (BI-CITT) is a multi-center, placebo-controlled, masked, clinical trial designed to compare the benefits of base-in prism for patients with convergence insufficiency (CI).
The goals of this clinical trial are:
- To compare the effectiveness of Base-in prism and Placebo eyeglasses for the treatment of CI in children
- To study the long-term effect of these treatments for CI
- To identify factors that may be associated with successful treatment of CI with base-in prism
