Abstract

To describe the current optical correction and present visual outcomes of schoolchildren identified with myopia during vision screening.
A cross-sectional analysis was conducted of data from 12,106 students aged 6.0-18.99 years in 36 schools in Yangzhou, China. Vision screening-identified myopia was defined using visual acuity (VA) and noncycloplegic refraction; current orthokeratology users were also included. VA is reported in five-mark notation with logarithm of the minimum angle of resolution (logMAR) equivalents. The primary and secondary outcomes were having a current optical correction and presenting corrected bilateral visual acuity (PCVA) ≥ 5.0 (≤0.00 logMAR) in both eyes amongst spectacle users, respectively. Modified Poisson regression accounted for school clustering. Sensitivity analyses examined refractive severity, VA thresholds and noncycloplegic classification error.
Overall, 7950/12,106 students met the screening criterion (65.7%). Of these, 5315 (66.9%) used an optical correction and 2635 (33.1%) had no recorded correction. Among 5251 spectacle users with valid measurements in both eyes, 2275 (43.3%) met the bilateral 5.0 (0.00 logMAR) threshold and 4976 (94.8%) satisfied a lower 4.7 (0.30 logMAR) threshold. Differences in the use of correction between educational stages were substantially smaller after adjustment for refractive severity.
Approximately one-third of students with vision screening-identified myopia had no recorded correction. Screening reports should identify both the use of correction and the presenting visual outcomes. The identification of reduced presenting vision justifies further assessment, but does not, by itself, indicate an inaccurate prescription or poor-quality care.
