The AAPOS Vision Screening Committee established the first guidelines for automated preschool vision screening in 2003. These primarily addressed the magnitude of refractive error that was (by consensus) thought to put a child at risk for the development of amblyopia. Since then, more data have emerged about the prevalence of amblyopia risk factors in young children from which it is clear that most children with these risk factors do not develop the condition. Likewise, technology has advanced, and screening instruments are now available that detect abnormalities other than amblyopia risk factors. The Committee has therefore reviewed the new evidence and adjusted its criteria.
