Ophthalmologic disorders and eye tracking in children with autism spectrum disorder (ASD)

We are conducting a research study about visual problems in children with Autism Spectrum Disorder (ASD). We believe that many children with autism may have undiagnosed eye problems because they cannot explain when they have trouble seeing and may not undergo routine eye exams. We hope to develop a method to screen for visual problems in using a new, non-invasive technology called eye tracking. We will use a camera to record your child’s eye movements as they watch video clips for 15-20 minutes.
