Manual measurements of strabismus are subjective, time consuming, difficult to perform in babies, toddlers, and young children, and rely on the examiner’s skill and experience.

An automated system, based on eye tracking and dedicated full occlusion glasses, was developed to provide a fast, objective, and easy-to-use alternative to the manual measurements of strabismus.

The objective of this study was to test the efficacy of the system in determining the presence of strabismus in children, as well as its type and the amount of deviation, in addition to differentiating between phorias and tropias.

Prospective, masked, inter-rater reliability study.

A prospective, masked, cross-sectional study included 69 children, aged 3-15 years.

A cover uncover test (CUT) and a prism alternating cover test (PACT) for the primary gaze, at a distance of 50 cm, were performed by two independent, masked examiners and by the automated system.
