Figure 1.

Receiver operating characteristic curves for detection of hyperopia, myopia, astigmatism, and anisometropia based on spherical equivalents or cylinder returned from the Spot Vision Screener (Welch Allyn, Skaneateles Falls, NY) relative to three gold standards. Gold standard 1 is the determination of these conditions according the 2013 amblyopia risk factors criterion. Gold standards 2 and 3 represent progressively more strict rules that determine the conditions (ie, more children will be categorized as having the condition). AUC = area under the curve
