Application of Eye-Tracking Technology in Assessing Binocular Vision Function in Paediatric Populations: A Scoping...

Area of Science:

• Ophthalmology
• Pediatric Optometry
• Biomedical Engineering

Background:

• Binocular vision anomalies are common in children.
• Early detection and monitoring are crucial for effective management.
• Traditional methods may have limitations in accuracy and accessibility.

Purpose of the Study:

• To review the application of eye-tracking technology for detecting and monitoring binocular vision anomalies in children.
• To identify specific eye-tracking parameters and models used in paediatric vision assessments.
• To evaluate the potential of eye-tracking as a non-invasive screening tool.

Main Methods:

• A scoping review following PRISMA guidelines was performed.
• Searches were conducted in Scopus, ScienceDirect, and PubMed (2015-2025).
• Keywords included "eye-tracking," "binocular," "vision," "anomalies," "paediatrics," and "children."

Main Results:

• 14 studies met the inclusion criteria from 77 initial citations.
• Eye-tracking systems can detect various binocular vision anomalies, including strabismus and amblyopia.
• The technology showed potential for improved accuracy and earlier diagnosis.

Conclusions:

• Eye-tracking technology is a valuable tool for paediatric vision care.
• It enables objective and earlier detection of binocular vision anomalies.
• Its non-invasive nature enhances clinical applicability for early screening.
