Summary

Eye-tracking measures show promise for early autism identification by objectively quantifying differences in social attention. These gaze-based tools demonstrated good accuracy in distinguishing autistic from nonautistic children, supporting their use as an adjunct diagnostic aid.

Area of Science:

  • Neuroscience
  • Developmental Psychology
  • Biomedical Engineering

Background:

  • Atypical gaze patterns are a hallmark of autism spectrum disorder (ASD), reflecting altered social attention and interest.
  • Eye-tracking technology offers an objective method to quantify these gaze differences, potentially serving as an early indicator for autism.
  • Existing diagnostic methods can be subjective and time-consuming; objective, quantitative measures are needed.

Purpose of the Study:

  • To systematically review and meta-analyze the diagnostic accuracy of eye-tracking-based gaze measures in identifying autism in children.
  • To evaluate the performance of various gaze-tracking paradigms and analytical methods.

Main Methods:

  • A systematic review and meta-analysis adhering to PRISMA-DTA guidelines.
  • Inclusion of 17 studies (n=4,256) published between 2015-2025 comparing gaze-tracking with standardized autism diagnoses.
  • Analysis using random-effects and hierarchical summary receiver operating characteristic (HSROC) models to estimate pooled diagnostic performance metrics.

Main Results:

  • The pooled HSROC AUC was 0.845, with a diagnostic odds ratio (DOR) of 15.03, sensitivity of 0.77, and specificity of 0.80.
  • Dynamic social stimuli and higher-frequency tracking systems yielded the best performance.
  • Despite high heterogeneity, consistent effect directions were observed across studies.

Conclusions:

  • Gaze-tracking tests effectively differentiate autistic and nonautistic children across various settings.
  • Eye-tracking-based measures show potential as a quantitative, observer-independent adjunct for early autism identification and clinical decision support.
  • Further research may refine these tools for broader clinical application.
