Abstract

Objective: ADHD patients show poor oculomotor control and recent studies show that attention-related eye vergence is weak in ADHD children. We aimed to assess vergence as a potential diagnostic biomarker for ADHD in adults.Method: We assessed the modulation in the angle of vergence while performing an attention task ( N = 144), comparing the results for adults previously diagnosed with ADHD ( N = 108) with age-matched clinical controls ( N = 36).Results: Significant differences in eye vergence response modulation between clinical controls and ADHD patients were documented. Diagnostic test accuracy was 79%.Conclusion: In combination with an attention task, eye vergence responses could be used as an objective marker to support the clinical diagnosis of adult ADHD.
