Abstract

Background: The recently released GoCheck Kids iPhone photoscreening app is designed to detect amblyopia risk factors (ARFs) in young children and includes remote review of images captured by smartphone. We aimed to evaluate the system's accuracy in detecting AAPOS guidelines ARFs.

Methods: Patients 6 months through 6 years of age at Medical University of South Carolina were recruited for this prospective study. Presence of age-specific ARF was determined based on a complete ophthalmic examination and compared with the GoCheck Kids recommendations.

Results: A total of 244 children were included (average age, 42 months; 51% male). Sensitivity of the GoCheck Kids iPhone with remote review to detect ARFs was 90.5%; specificity, 68.1%; positive predictive value, 56.8%; negative predictive value, 94.0%. Two of the 7 false negative results had hyperopia of >4 D, 4 had astigmatism, and 1 had anisometropia. Remote review of all images improved sensitivity.

Conclusions: The GoCheck Kids app had good sensitivity and adequate specificity in detecting AAPOS ARFs in our enriched cohort of young children.
