Real-World Application of Home Visual Acuity Testing for Pediatric Teleophthalmology During the COVID-19 Pandemic

Abstract

Purpose: To review the ability of home visual acuity testing during teleophthalmology consultations to accurately assess visual acuity in pediatric patients in a real-world setting. Methods: This was a retrospective study of pediatric patients who were examined via teleophthalmology consultation due to the coronavirus disease 2019 (COVID-19) pandemic-related community restrictions between May and June 2020 at a single private ophthalmology practice. Home visual acuity findings were compared with the subsequent in-person assessment to determine agreement between measures. Results: Forty-three patients (86 eyes) were included in the study. The mean patient age at the time of teleophthalmology assessment was 75.9 months (range: 29 to 173 months). The correlation between home visual acuity findings and subsequent in-person assessment across all participants was 0.56 ( P < .001). The upper and lower limits of agreement were 0.38 logarithm of the minimum angle of resolution (logMAR) units and −0.33 logMAR. The correlation reduced to 0.46 ( P = .013) in patients younger than 5 years and increased to 0.70 ( P < .001) in patients 8 years and older. Conclusions: Home visual acuity assessment for teleophthalmology is of increased clinical value in older pediatric patients. In-person assessment by a trained clinician is the optimal method to determine visual acuity. Because home visual acuity assessment may be necessitated by local and global factors, further research is required regarding the optimal methods for assessment, particularly in younger patients.
