This study showed that office-based vision therapy is more effective than home-based pencil push-ups for young adults. Pencil push-up treatment was no more effective than placebo therapy.

The American Optometric Association News reviews the result of the CITT study showing that office-based vision therapy is more effective than home-based therapy.

The rate of improvement is more rapid for clinical measurements than for symptoms in children undergoing treatment for CI. Office-based vision therapy results in a more rapid improvement in symptoms, and clinical measures, and a greater percentage of patients reaching pre-determined criteria of success when compared with home-based pencil push-ips, home-based computer therapy or placebo therapy.

Surveys requesting doctors to indicate which treatment(s) they prescribed and believed to be most effective for symptomatic CI patients were mailed to 863 optometrists and 863 ophthalmologists in the United States.

This pilot study was the first randomized clinical trial of vision therapy for convergence insufficiency. The objective was to compare office-based vision therapy, home-based pencil push-ups, and office-based placebo vision therapy as treatments for symptomatic convergence insufficiency in children 9 to 18 years of age. The results of the study showed that only office-based vision therapy was an effective treatment for convergence insufficiency. Home-based pencil push-ups was no more effective than placebo treatment.,
