Brief Summary

Attention-Deficit Hyperactivity Disorder (ADHD) is considered to be one of the most prevalent chronic health conditions in children. It affects between 4% and 12% of young children. A relationship between convergence insufficiency (eye teaming) and ADHD has been shown. However, the effect of ADHD medications on focusing and eye teaming has not been previously investigated. Therefore, the purpose of this study is to determine the effect of ADHD medication on focusing and eye teaming skills.
