Insights
Eye-tracking technology offers a promising, non-invasive method for early detection and monitoring of binocular vision anomalies in children. This advancement aids in diagnosing conditions like strabismus and amblyopia, improving paediatric vision care.
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.
Abstract:
Background: This review discusses the application of eye-tracking technology in the detection and monitoring of binocular vision anomalies among children. Methods: A scoping review using PRISMA guidelines was conducted through Scopus, ScienceDirect, and PubMed using the keywords "eye-tracking," "binocular," "vision," "anomalies," "paediatrics," and "children" from 2015 to 2025. Studies excluded were not written in English, did not apply the eye tracker as a research tool, involved an ineligible population, or involved non-human subjects. Results: The search strategy identified 77 citations, yet only 14 studies met the inclusion criteria. This review revealed a variety of binocular vision anomalies detectable through eye-tracking systems, along with the specific models and parameters employed in these assessments. Application of eye-tracking technology in diagnosing conditions such as strabismus and amblyopia demonstrated potential for improved accuracy and early detection. Discussion: Eye-tracking technology demonstrates considerable potential for the detection and monitoring of binocular vision anomalies in children, particularly as a non-invasive method for early screening, thereby strengthening its clinical applicability. By assessing fixation stability, saccadic movements, and vergence responses, eye-tracking allows for the early detection of subtle visual anomalies, especially in the paediatric population. Conclusions: Eye-tracking technology represents a valuable advancement in paediatric vision care, enabling the more objective and earlier detection of binocular vision anomalies in the paediatric population.
