The University of California Los Angeles (UCLA) Preschool Vision Program (UPVP) is a community outreach program that provides free vision screenings and prescription eyeglasses to underserved preschool children across Los Angeles County. This study aims to investigate longitudinal visual changes among children who had significant refractive error and were given eyeglasses by UPVP.
Preschool children were assessed and followed up by UPVP between 2015 and 2017. Except for amblyopia, children with significant ophthalmic pathologies were excluded. Data including best-corrected distance visual acuity (BCVA), cycloplegic refraction, and eyeglasses prescription provided for the right eye were analyzed. Paired statistical analysis was performed using Wilcoxon signed rank test.
During the study period, 103 preschoolers had complete follow-up exams. Mean±standard deviation (range) BCVA at initial exam was 0.22±0.13 (0.00 – 0.54) logMAR. Mean spherical and astigmatic errors respectively were -0.55±2.12 diopters(D) (-7.50 – +5.00D) and 2.32±1.08D (0.00 – +5.50D), with refractive spherical equivalent (RSE) being 0.62±2.09D (-6.38 - +5.75D). Mean RSE of the eyeglasses prescription given at initial exam was -0.04±1.57D.At follow-up examination after 11.3±2.6 months, 66% of returning patients were wearing glasses prescribed from the initial exam. Follow-up mean BCVA was 0.17±0.12 (0.00 – 0.48, p<0.001) logMAR. Mean RSE was significantly lower at 0.34±2.39D (-9.50 - +6.00D, p=0.034), while mean spherical and astigmatic error were -0.82±2.51D (-11.50 - +5.00, p=0.05) and 2.33±1.20D (0.00 – +5.50D, p=0.44). A new prescription of eyeglasses was given to most children (n=99) at follow-up examination, with mean RSE of -0.16±1.77D.
Children receiving eyeglasses from UPVP often have high degrees of ametropia, including progressive high myopia. Early detection of refractive error and intervention with corrective eyeglasses can improve vision of children in underserved communities.
