This prospective study aimed to determine the positive predictive value (PPV) of patients referred to a pediatric ophthalmic practice in Alaska. Young children were photoscreened with Gobiquity app on a Nokia model 1020 smartphone; 217 children were referred. Time from screen to ophthalmic exam was 0-190 days; mean 39. There was a referral rate of 5% from the total number screened. Mean spectral domain (SD) PPV was 68%±3% (95% CI of 62-74%) using 2013 AAPOS guidelines. Referrals were 25% for high anisometropia, 31% for hypermetropia and 15% for myopia. Screening was comparable to other commercial screeners.
