Many vision disorders are undetectable without a comprehensive eye examination. The most common is Convergence Insufficiency or CI. The CITT, or Convergence Insufficiency Treatment Trial, is a multicenter study funded by the National Institute of Health. The members of the CITT found its prevalence to occur in approximately 10-15% of the regular population! It often is associated with symptoms such as double vision, eyestrain, headaches, blurred eye strainision, and loss of place while reading or performing near work. An often overlooked symptom is avoidance. A child may not report the previously stated symptoms because they refuse to read long enough for them to occur.

The CITT proved that pencil push-up therapy or base-in prism glasses used in isolation were not effective, and that home-alone therapy was equivalent to placebo therapy. This is where the science becomes pivotal. In office optometric vision therapy was the most successful form of treatment for CI.

Following the diagnosis of a binocular vision disorder, your doctor at NSVC will present appropriate treatment options to remedy the situation. These may include prescription eyewear, modification of your school or work ergonomic environment, and/or vision therapy.
