A Predictive Model for Amblyopia Risk Factor Diagnosis after Photoscreening

Abstract

The United States Preventive Services Task Force recommends vision screening to detect amblyopia or amblyopia risk factors (ARFs) at least once between 3 and 5 years of age.1,2 Photoscreeners, including the Plusoptix S12C (Plusoptix, Inc), are automated tools that estimate refractive error; their use in preschool vision screening is dependent on the establishment of cutoff values for each type of refractive error, resulting in a binary pass-or-refer outcome for each metric.3
