2021 AAPOS Guidelines for the Welch Allyn Spot Vision Screener

As instrument-based pediatric vision screening technology has evolved, the American Association for Pediatric Ophthalmology and Strabismus (AAPOS) has developed uniform guidelines (2003, updated 2013) to inform the development of devices that can detect specified target levels of amblyopia risk factors (ARFs) and visually significant refractive error.* In 2021, the AAPOS Vision Screening and Research Committees revealed an apparent high level of over-referral for non-amblyopic, symmetric astigmatism, prompting the current revision.1

The Spot Vision Screener criteria was developed in accord with the American Academy of Pediatric Ophthalmology and Strabismus (AAPOS) and American Academy of Pediatrics (AAP) recommendations for instrument-based vision screening. The criteria is age specific to assist with early detection of amblyopic risk factors in children.
