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 vision, 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.

Convergence insufficiency is associated with negative academic behavior and its treatment can lead to improved academic behavior as noted in this research paper.
