Convergence Insufficiency Treatment Trial Attention & Reading Trial (CITT-ART) Watch the following video of a boy with convergence insufficiency attempt to read. 9. Convergence Insufficiency Treatment Trial (CITT) Study Group. R. John Leigh and David S. Zee. Active treatment: A multi-site randomized clinical trial funded by the National Eye Institute called the Convergence Insufficiency Treatment Trial showed: The best treatment for CI is supervised vision therapy in a clinical office with home reinforcement (15 minutes of prescribed vision exercises done in the home five days per week). Ophthalmic Epidemiol. Approximately 208 subjects will be entered into the study and assigned to one of four treatment groups. Vergence Eye Movements. Oxford University Press; 2015. But for people with symptoms, treatment with eye-focusing exercises can increase the eyes' convergence ability. Convergence Insufficiency Treatment Trial Study Group. Treatment of symptomatic convergence insufficiency in children enrolled in the convergence insufficiency treatment trial-attention & reading trial: a randomized clinical trial… this treatment was as effective or more effective than the other treatment modalities in the survey. It is to be administered before any other clinical testing. The convergence insufficiency treatment trial: design, methods, and baseline data. At that time the group used the acronym CIRS (Convergence Insufficiency Reading Study). Scheiman M, Cotter S, Kulp M, Convergence Insufficiency Treatment Trial Study Group, et al. A multi-center clinical study, called the Convergence Insufficiency Treatment Trial, was designed to compare different treatment options for convergence insufficiency in children. The Convergence Insufficiency Treatment Trial Group found that for adults aged 19-30, 50% receiving office-based vision therapy for CI were either “improved” or “cured” after 12 weeks based on symptoms and clinical measures. Harrison RL. Because results of pencil push-ups varied so much, a study was conducted by the National Eye Institute is known as the Convergence Insufficiency Treatment Trial (CITT). The 12-week study, known as the Convergence Insufficiency Treatment Trial (CITT), found that approximately 75 percent of those who received in-office therapy by a trained therapist plus at-home treatment reported fewer and less severe symptoms related to reading and other near work. This treatment sequence is a wellaccepted approach for treatment of convergence insufficiency and has been successfully implemented in previous randomized clinical trials (Scheiman et al., 2008;. Treatment, which can take place in the office with a trained therapist or at your home, might include: Pencil pushups. Vergence Eye Movements. This was the first well-designed study comparing the different treatments. The purpose of this study is to describe clinical characteristics, treatments, and one-year outcomes for adults who have convergence insufficiency, divergence insufficiency… The first, published in Archives of Ophthalmology demonstrated that computer exercises when combined with office based vision therapy/orthoptics were more effective than "pencil pushups" or computer exercises alone for convergency insufficiency in 9- to 18-year-old children. Eye coordination problems like convergence insufficiency generally cannot be improved with eye glasses or surgery. 152 Treatment Modalities for Convergence Insufficiency—Scheiman et al. Results from the earlier Convergence Insufficiency Treatment Trial (CITT), published in Ophthalmology in 2008, showed office-based vision therapy to be the most effective treatment for improving convergence and ameliorating symptoms, and that treatment effects were long-lasting. Convergence Insufficiency Treatment Trial (CITT) Investigator Group. Randomised clinical trial of the effectiveness of base-in prism reading glasses versus placebo reading glasses for symptomatic convergence insufficiency in children. The Convergence Insufficiency Treatment Trial is the first large-scale, randomized clinical trial to evaluate active treatments for symptomatic CI in children.

Convergence Insufficiency Treatment Trial Study Group. The purpose of this study was to report changes in clinical signs and symptoms of convergence insufficiency (secondary outcome measures) from a multicenter clinical trial (Convergence Insufficiency Treatment Trial-Attention & Reading Trial [CITT-ART]) evaluating the effectiveness of vergence/accommodative therapy for improving reading and attention in children with symptomatic convergence … Identification of the most effective treatment regimen is important because of the high prevalence of this binocular vision disorder and its potential effect on reading and other near visual activities. 3. Convergence insufficiency is when the eyes have trouble working together when reading or doing close work, which can cause eyestrain, blurred vision, headaches, and an inability to concentrate. Objective: This report describes the design and methodology of the Convergence Insufficiency Treatment Trial (CITT), the first large-scale, placebo-controlled, randomized clinical trial evaluating treatments for convergence insufficiency (CI) in children.We also report the clinical and demographic characteristics of patients. Optometry and Vision Science, Vol. Ophthalmic Epidemiol. A Study of Clinical Characteristics, Treatments, and One-Year Outcomes of Adults with Strabismus Rochester, MN . 2008;126(10):1336-49.
