A device for the assessment of both visual acuity and strabismus to identify amblyopic risk factors in preverbal and verbal children – pilot study

Abstract

Instrument based vision screening for high refractive error and amblyopia is recommended for infants and children aged 1-3 years by the AAPOS. Eye-N-JOY (ENJ) is a novel device (patent no. US 9,844,317 B2), including a tablet, infrared camera, LCD glasses and cloud-based software. While child is watching images on the tablet screen, camera sensors track the child's eye movements as they respond to optical stimulation. The device provides a “pass” or “refer” result. The study assessed the accuracy of the ENJ device in identifying low vision or the presence of amblyopia risk factors in children
