Vision Therapy Research

There is a great deal of research involving vision therapy, vision and learning, vision and reading, and concussion/brain injury and vision.


The Convergence Insufficiency Treatment Trial  (CITT) was a National Eye Institute funded nationwide study that compared various treatments for convergence insufficiency,  the most common eye muscle disorder.

CITT is the most extensive scientific study of vision therapy done to date.

The study involved pediatric optometrists and ophthalmologists, and Dr. Gallaway was the Principal Investigator at one of the sites, the Pennsylvania College of Optometry at Salus University. The study results published in 2008 showed that the most effective treatment for convergence insufficiency is office based vision therapy, which is the treatment offered at our office. Home based treatments were no more effective than placebo therapy.

Children in the study who were successfully treated were followed for a year and the results showed that the improvements were long lasting. Children who were successful also showed improvement in academic behaviors  such as completing homework and classroom work, as well as attention span and willingness to read.

A Cochran Review of evidence based treatment for convergence insufficiency reviewed numerous studies and concluded that office based vision therapy is the best treatment. Also, a compilation of research articles on vision therapy can be found here.

COVD  is the College of Optometrists in Vision Development, the professional organization that board certifies optometrists in vision therapy. COVD has compiled extensive bibliographies of research on  vision and learning, vision-based reading problems, and brain injury/concussion.

Clinical Practice Guidelines from the American Optometric Association detail the research support for the care of patients with amblyopia, strabismus, learning-related vision problems, and accommodative and vergence dysfunction.
