To assess the validity and reliability of the Convergence Insufficiency Symptom Survey (CISS) in children aged 9 to 18 years. Secondary outcomes were near point of conver-gence and positive fusional vergence at near. First: Convergence excises such as near point focussing performed several times daily can strengthen your convergence , your other choice would be reading glasses with weak prisms to alleviate symptoms they would be prescription and not over the counter. Main Outcome Measures: Convergence Insuffi-ciency Symptom Survey score after 12 weeks of treat-ment. Harrison RL. Comment on Arch Ophthalmol. We also report the clinical and demographic characteristics of patients. Cotter S, Kulp M, Scheiman M, Hertle R, Mitchell GL, Rouse M; Convergence Insufficiency Treatment Trial Executive Committee. During a routine eye examination, convergence weakness may be diagnosed even without the above-mentioned symptoms. Once again, the results proved the efficacy of vision therapy treatment over other modalities that were in use at the time. The study compared various treatments, such as home-based and in-office treatment. The Neurology of Eye Movements. 2008 Jan-Feb. 15 (1):24-36. . In 2005 Scheiman et al. published a clinical trial in Optometry and Vision Science on the vision therapy treatment of convergence insufficiency in young adults ages 19-30. However, the child or adult with significant symptoms and other findings consistent with convergence insufficiency can have a … 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. 5. The Convergence Insufficiency Treatment Trial (CITT) recommended in-office vision therapy as a treatment option for convergence insufficiency (Scheiman, 2005). The Convergence Insufficiency Treatment Trial study conducted by the National Eye Institute (NEI) revealed that supervised vision therapy with home reinforcement is the most effective treatment for CI. 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. If you have this condition, one or both eyes move outward when you look at … with convergence insufficiency. Convergence insufficiency (CI) is an eye disorder where your eyes don’t move at the same time. Optom Vis Sci. 2019 Nov;96(11):825-835. doi: 10.1097/OPX.0000000000001443. In some cases, because these lenses reduce the visual demands on the visual system this is all that is needed. 2008 Oct;126(10):1455-6. R. John Leigh and David S. Zee. Methods: In a randomized clinical trial, 221 children aged 9 to 17 years with symptomatic convergence insuf-ficiency were assigned to 1 of 4 treatments.

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. Some patients test in the office as having poor convergence; however, they are asymptomatic. Main Outcome Measures—Convergence Insufficiency Symptom Survey (CISS) score after 12 weeks of treatment. CI is usually accompanied by a reduced near point of convergence (NPC), decreased convergence amplitudes or an exodeviation (usually > 10 prism diopters) at near. N2 - 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. 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. 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. 1.
