- Borsting E, Rouse M, Chu R. Measuring ADHD behaviors in children with symptomatic accommodative dysfunction or convergence insufficiency: a preliminary study. Optometry. 2005;76:588–92. [PubMed]
The results from this preliminary study suggest that school-aged children with symptomatic accommodative dysfunction or convergence insufficiency (eye movement disorders) have a higher frequency of behaviours related to school performance and attention as measured by the a survey called the Connors Parent Rating Scale–Revised Short Form. The survey uses 27 questions to test a broad range of school-related behaviors in the following categories: oppositional, cognitive problems/inattention, hyperactivity, and ADHD Index.

In this study, the researchers found that people diagnosed with ADHD were three times more likely to have convergence insufficiency than the general population.
