Once again, the results proved the efficacy of vision therapy treatment over other modalities that were in use at the time. 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. There is an algorithm to calculate the score and this can be repeated after treatment to determine the subjective level of improvement and improvement in symptoms. Treatment of acquired convergence insufficiency will require the prescription of spectacles. asthenopia associated with convergence, but in the absence of a receded near point of convergence, exophoria at near, or reduced positive relative convergence.3,7 The definition of CI has important diagnostic and treatment implications.

The Convergence Insufficiency Treatment Trial (CITT) recommended in-office vision therapy as a treatment option for convergence insufficiency (Scheiman, 2005). Convergence insufficiency (CI) is a common binocular vision disorder characterized by exophoria greater at near than at distance, a receded near point of convergence, and reduced positive fusional vergence (convergence amplitudes) at near. Participants age 9 to14 years in grades 3 to 8 If you have this condition, one or both eyes move outward when you look at … A program of vision therapy may be needed to improve eye coordination abilities, reduce symptoms, and alleviate discomfort when doing close work.. Convergence Insufficiency (CI) is characterized by a decreased ability to converge the eyes and maintain binocular fusion while focusing on a near target.

During a routine eye examination, convergence weakness may be diagnosed even without the above-mentioned symptoms. Methods: We prospectively randomized children … Response to editorial about the convergence insufficiency treatment trial. (3,4) The latter version has since been used as the primary outcome measure for three Convergence Insufficiency Treatment Trial (CITT) pilot studies (5,6,7) and was used in the CITT, a large-scale randomized trial evaluating the effectiveness of active … In other cases however, visual therapy will also be needed to rebuild and develop the visual stamina and convergence skills. Treatment of Symptomatic Convergence Insufficiency in Children Enrolled in the Convergence Insufficiency Treatment Trial-Attention & Reading Trial: A Randomized Clinical Trial. Purpose. The CISS is the primary outcome measure for a pilot study evaluating two different treatments for convergence Convergence insufficiency (CI) is an eye disorder where your eyes don’t move at the same time. 2008 Jan-Feb. 15 (1):24-36. . Methods: We prospectively randomized children … published a clinical trial in Optometry and Vision Science on the vision therapy treatment of convergence insufficiency in young adults ages 19-30. Objective To compare vision therapy/orthoptics, pencil push-ups, and placebo vision therapy/orthoptics as treatments for symptomatic convergence insufficiency in children 9 to 18 years of age.. Methods In a randomized, multicenter clinical trial, 47 children 9 to 18 years of age with symptomatic convergence insufficiency were randomly assigned to receive 12 weeks of … Cotter S, Kulp M, Scheiman M, Hertle R, Mitchell GL, Rouse M; Convergence Insufficiency Treatment Trial Executive Committee.

This proposal is for the Nova Southeastern University to serve as a clinical center for the Convergence Insufficiency Treatment Trial - Attention and Reading Trial (CITT-ART), a multicenter randomized, placebo controlled, clinical trial designed to evaluate the effects of treatment for symptomatic convergence insufficiency (Cl) on measures of reading … The convergence insufficiency treatment trial (CITT) study group has performed multiple investigations examining the effectiveness of various treatment regimens on the symptoms and signs of CI.1, 10, 11, 12 CITT studies showed that office-based convergence accommodative treatment was most successful, improving 73% of children with CI. We also report the clinical and demographic characteristics of patients. The American Optometric Association and the 2008 Convergence Insufficiency Treatment Trial … Secondary outcomes were near point of conver-gence and positive fusional vergence at near. 1 – 4 In studies that used standardized definitions of CI, investigators have reported a prevalence of 4.2% to 6% in school … In the Convergence Insufficiency Treatment Trial (CITT),1 the patient answers each question with the following: never, infrequently, sometimes, fairly often, and always.
