Eye Tracking as a Treatment Monitoring Tool for Autism: A Multilevel Meta-Analysis.

PMID 41235721WHAT IT FOUND
Eye-tracking measures showed small, significant changes after autism interventions, suggesting they can track treatment effects.
However, baseline eye-tracking did not significantly predict later developmental gains, meaning it cannot currently be used to forecast how well a specific child will respond to therapy.
Key findings
01There was a modest, significant summary effect size for changes in eye-tracking outcomes from pre- to post-treatment.
02The analysis revealed a moderate, non-significant summary effect size for the correlation between baseline eye-tracking outcomes and changes in developmental outcomes.
03Changes in eye-tracking outcomes were significant for dynamic stimuli (videos) but not for static stimuli (images).

What it does not show
The analysis for predicting treatment response was exploratory and based on a small number of studies (39 effect sizes), limiting its robustness. There is no established Minimal Clinically Important Difference (MCID) for eye-tracking measures in autism, making it difficult to judge if the observed changes are functionally meaningful. The study did not include backward or forward searches of references, which may have missed relevant data. Grouping treatments into broad categories (e.g., behavioral, biomedical) may have oversimplified complex intervention mechanisms. High heterogeneity (I² > 70%) was observed across studies, indicating variability in how effects were measured and reported.

The easy way to misread this
Do not interpret the significant change in eye-tracking outcomes as evidence that the intervention improved social functioning. The study notes that these gaze changes are incremental and their translation to functional gains in daily life remains uncertain, especially since baseline eye-tracking did not significantly predict developmental outcomes.
