•Brief excursus on the eye tracking technology and its application in the field of neurodevelopmental disorders•Eye tracking is a novel approach to evaluate ADHD clinical characteristics•Eye movements could be represent a possible biomarker of ADHD In recent years, the study of eye movements has increasingly become a window into neurological function and processes. This paper reports data about applications of eye-tracking technology in the field of neurodevelopmental disorders, especially in studying the clinical characteristics of ADHD. These studies indicated that eye-tracking approach represents a non-invasive methodology to test specific domains, such as attention networks and inhibition control, in an objectively and reliable way in youths. Although the studies results are still not conclusive, eye-tracking represents a potential valid support for clinicians in identifying specific biomarkers to orient ADHD diagnosis and the best intervention strategies.
