Effect of Convergence Insufficiency on Everyday Activities

Recent studies that have suggested a possible relationship between convergence insufficiency and Attention Deficit Hyperactivity Disorder (ADHD). Dr Eric Borsting from the Southern California College of Optometry found that the symptoms frequently reported in convergence insufficiency such as loss of concentration when reading or reading slowly are similar to behaviors associated with ADHD (inattentive type), such as, failure to complete assignments and trouble concentrating in class.

The Convergence Insufficiency Treatment Trial investigators developed a questionnaire called the Academic Behavior Index (ABS). The Academic Behavior Survey is a 6-item survey that evaluates parent concern about school performance and the parents' perceptions of the frequency of problem behaviors that their child may exhibit when reading or performing schoolwork (such as: difficulty completing work, avoidance, and inattention). The survey was administered to the parents of 221 children 9-17 years old with symptomatic convergence insufficiency prior to enrolling into the Convergence Insufficiency Treatment Trial and to 49 children with normal vision. The results of this study showed that 15% of the convergence insufficiency group and children with normal vision were classified as ADHD by parental report. The total ABS score for the symptomatic convergence insufficiency with parent-report of ADHD group was significantly higher than the symptomatic convergence insufficiency with no parent-report of ADHD group. The authors concluded that both children at risk for ADHD or related learning problems should have a comprehensive vision evaluation to assess the presence of convergence insufficiency as a contributing factor.
