Title: Convergence Insufficiency Treatment Trial - Attention and Reading Trial (CITT-ART)
Brief Summary: CITT-ART is a multicenter study (8 locations around the United States) of 324 children ages 9 to \<14 years with symptomatic convergence insufficiency (CI). The purpose of this study is to see if office-based therapy for convergence insufficiency (CI) improves reading ability and attention. CI is an eye-teaming problem where the eyes would like to drift outward when reading or doing close work. When eyes drift out, double vision can happen. To prevent double vision one must use extra effort to keep the eyes from going out. This extra effort can cause symptoms that can interfere with reading and working comfortably at near. These symptoms often include eyestrain, blurred vision, headaches, double vision, and loss of place when reading or performing tasks at near. In a prior study we found that therapy improves these symptoms. In this study we are looking at whether the therapy improves reading and attention
