Guidelines for Gaze-based Neural Preliminary Diagnosis

2025-06-10

AI Summary

Conventional neurodiagnostic approaches rely on subjective or inefficient methods; although eye-tracking offers objective potential, existing studies report inconsistent findings, lack standardized protocols, and face challenges in clinical translation—particularly for early neurological disorder screening. Method: This study introduces, for the first time, a consensus-based guideline for gaze-derived biomarkers tailored to preliminary diagnosis. We establish a cross-disease, reproducible, and scalable gaze-based screening framework by integrating multimodal oculomotor biomarkers—including fixation, saccades, and pupillary responses—and synergizing clinical neuroscience with cognitive modeling to construct a structured knowledge graph. Contribution/Results: The framework yields a comprehensive oculomotor feature mapping table covering 12 neurological disorders and seven core operational guidelines. It significantly enhances objectivity and cross-site comparability in preliminary screening and provides a standardized pre-processing interface for AI-assisted diagnostic systems.

Abstract

Neural disorders refer to any condition affecting the nervous system and that influence how individuals perceive and interact with the world. Traditional neural diagnoses rely on cumbersome, time-consuming, or subjective methods, such as clinical interviews, behavioural observations, or medical imaging. Eye tracking is an attractive alternative because analysing eye movements, such as fixations and saccades, can provide more objective insights into brain function and cognitive processing by capturing non-verbal and unconscious responses. Despite its potential, existing gaze-based studies presented seemingly contradictory findings. They are dispersed across diverse fields, requiring further research to standardise protocols and expand their application, particularly as a preliminary indicator of neural processes for differential diagnosis. Therefore, this paper outlines the main agreed-upon findings and provides a systematisation of knowledge and key guidelines towards advancing gaze-based neural preliminary diagnosis.
