Comparison of the GoCheck Kids and Spot Screener photoscreening devices for the detection of amblyopia risk factors using 2021 AAPOS recommendations.

Purpose: To compare the Spot Vision Screener (SPOT) to the GoCheck Kids mobile application (GCK) in the evaluation of amblyopia risk factors (ARFs), according to updated 2021 AAPOS guidelines for instrument-based pediatric vision screening.

Methods: SPOT, GCK using horizontal and vertical images (two-photo mode), and a complete eye examination (CEE) were performed on children ages ≥1 to <7 years referred to a pediatric ophthalmologist from October 2020 to December 2022 for a failed vision screen based on manufacturer guidelines. The primary outcomes were sensitivity, specificity, and positive predictive value (PPV) for each photoscreener.
