ABSTRACT
PURPOSE: To determine whether a low-technology novel virtual vision screening protocol can reliably screen pediatric visual acuity. METHODS: Give Kids Sight Day (GKSD), an annual out-reach program, aims to provide free vision screening and ophthalmic care to underserved children in Philadelphia, Pennsylvania. Children were screened virtually through the low-technology protocol. Based on screening results, 152 children were provided in-person eye examinations. Data from in-person examinations were compared to data from virtual screenings for 151 children who were seen in-person. RESULTS: Of 475 children screened virtually, 152 children were seen in-person for examination, and 151 children were included in the analysis. Results from 151 children (mean age: 10.7 years, age range: 5 to 18 years, 43% female, 28% speaking a non-English language) were reviewed. There was a moderate correlation (R = .64, P < .0001; n = 100 children) between screening and in-person visual acuity without refractive correction and a strong correlation (R = 0.82, P < .0001; n = 18 children) between screening and in-person visual acuity with refractive correction. Of the 140 children who were seen in-person, 133 children were provided glasses prescriptions. Seventeen children required a referral to a pediatric ophthalmologist for evaluation of ophthalmic conditions, most commonly strabismus (5.3%) and amblyopia (4%). CONCLUSIONS: The GKSD virtual visual acuity testing demonstrated good correlation with in-person visual acuity testing, supporting the virtual screening approach as a useful tool for future applications in widespread community vision outreach programs. Further studies are needed to refine virtual ophthalmic screening to optimize its applications in bridging the gaps in ophthalmic care. [J Pediatr Ophthalmol Strabismus. 20XX;X(X):XX-XX.].
