Validation of the Pediatric Vision Scanner in a normal preschool population.

ABSTRACT:

Purpose

To assess the Pediatric Vision Scanner (PVS), a handheld vision screening device designed to test for amblyopia and strabismus, in a general pediatric population.

Methods

In this prospective study, trained research staff screened 300 eligible children 24-72 months of age with no known eye conditions for amblyopia and strabismus using the PVS. A pediatric ophthalmologist masked to PVS screening results then performed a comprehensive eye examination. Sensitivity and specificity of the PVS was calculated with a 95% confidence interval.

Results

Based on the gold standard eye examination, 6 children (2%) had amblyopia and/or strabismus. The PVS detected all 6 cases, yielding a sensitivity rate of 100% (95% CI, 54%-100%). The PVS referred 45 additional children (15%
