Is this trial a fit for you?
✓Likely a good fit
Ideal candidates include children aged 2 to 12 years with a clinical diagnosis of Autism Spectrum Disorder or typically developing children within the same age range.
✕Probably not a fit
Patients with known uncorrected visual pathologies or personal neurological pathologies may not benefit from this study.

What this trial studies
This observational study aims to identify behavioral and physiological markers of social alterations in children with Autism Spectrum Disorder (ASD) compared to typically developing peers. The study will utilize eye tracking technology to evaluate social disorders, estimating oculometric and pupillometric indices as potential biomarkers for ASD. It will be conducted in two phases over four years, with the first phase focusing on experimental validation in typical children and adults, and the second phase testing identified biomarkers on a larger population including other neurodevelopmental disorders.
Why it matters
Potential benefit: If successful, this study could lead to the development of objective biomarkers for diagnosing and evaluating Autism Spectrum Disorder.
How similar studies have gone: While the use of eye tracking in evaluating social processing is gaining traction, this specific approach to identifying biomarkers in ASD is relatively novel and has not been extensively tested.
