Our pilot study aimed to compare vision-screening results using EyeSpy software on an off-the-shelf laptop computer performed by a lay screener to the results of a gold-standard professional eye examination by a pediatric ophthalmologist. In addition, the video game format allows for automated testing, which eliminates the need for training and certification of vision-screening proctors thus it allows screenings to be performed by lay volunteers or other school personnel. Computer software applications allow standardization of logic protocols for vision screenings. 3 Computers are readily available in most schools in the United States, and vision screening software is easily distributed.
The video game format, with highly engaging graphics, motion, and sound, appeals to children.
In addition to visual acuity, it incorporates an analysis of binocular function. Professional examinations provide a comprehensive assessment of vision but are cost prohibitive for repeated testing during school years for all children.ĮyeSpy 20/20 (VisionQuest 20/20, Mesa, AZ) is an automated computer program that assesses vision while a child plays a video game. 7 Visual acuity is the most widely used method for screening vision in school-aged children however, visual-acuity testing in schools is not standardized, and binocular vision is often not tested. Vision screening in school-aged children has been made even more relevent by the results of a recent study suggesting that amblyopia therapy is effective even at older ages. 1 - 6 Ideally, children should have repeated vision screening as they age since refractive errors and disruptions in binocular vision can develop at any age. Vision screening for school-aged children is important to detect uncorrected refractive errors, problems with binocular vision, and missed amblyopia.
