Two recent studies suggest that a newly developed eye-tracking tool may revolutionize the diagnosis of autism in young children. Currently, families often face long wait times for a diagnosis, and even then, the diagnosis may not be definitive. However, this tool, called EarliPoint Evaluation, has been cleared by the US Food and Drug Administration to assist clinicians in diagnosing and assessing autism.
The hope is that this technology can enhance the diagnostic process by providing objective measurements of a child’s eye movements during social interactions. It is not meant to replace expert clinicians but rather to support their assessments with concrete data.
Traditionally, autism is diagnosed based on a clinician’s evaluation of a child’s developmental history, behaviors, and parental reports. This process can be time-consuming and may miss subtle behaviors, especially in younger children. The eye-tracking tool tracks a child’s gaze as they watch videos of other children’s social interactions. By analyzing how a child with autism responds differently to these videos, a diagnosis can be made with greater accuracy.
The studies found that the eye-tracking measurements predicted clinical assessments with a high degree of accuracy, showing sensitivity and specificity rates of around 80%. In one study, 475 children between 16 and 30 months old were assessed for autism using the tool, and the results showed a 71% accuracy rate in diagnosing autism. Another study with a larger group of children ages 16 to 45 months showed similar effectiveness.
These findings suggest that using eye-tracking measurements as a biomarker for diagnosing autism could significantly reduce the time needed for diagnosis and enable earlier intervention. While the assessment of expert clinicians will always be important, this technology has the potential to enhance and expedite the diagnostic process, ultimately benefiting families and children with autism.
