New Research on Convergence Insufficiency

The National Eye Institute, a division of the National Institutes of Health for the U.S. Department of Health and Human Services, released a statement concerning the effectiveness of office-based vision therapy for treatment of Convergence Insufficiency.

 

Dr. Mitchell Scheiman, FCOVD, has completed 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 after the office-based vision therapy.

 

"There are no visible signs of this condition; it can only be detected and diagnosed during a comprehensive eye examination," said Dr. Scheiman. "However, as this study shows, once diagnosed, CI can be successfully treated with office-based vision therapy by a trained therapist along with at-home reinforcement."
