Margines JB, Huang C, Young A, et al. - Researchers planned this retrospective assessment of a screening program in order to compile the outcomes of 5 years of vision screening with the University of California, Los Angeles (UCLA) Preschool Vision Program (UPVP). Overall 93,097 children underwent visual acuity and undilated noncycloplegic refractive screening between 2012 and 2017 using an autorefractor in the UPVP. They detected hyperopia, myopia, and astigmatism in 61% (4,018), 20% (1,336), and 93% (6,122) of children, respectively, among the examined population. Higher rates of astigmatism and worse visual acuity were observed in Latino children vs all other races/ethnicities. The correct prediction of the requirement of glasses 93% of the time was enabled by an astigmatism cutoff of ≥ 1.50 diopters (D) in either eye. A rise in the positive predictive value to 96% was noted when this cutoff was increased to ≥1.50 D in both eyes. A total of 780 children had refractive amblyopia, and of these, 211 (27%) were bilaterally amblyopic. The effects of this largest published sample of vision screening outcomes on preschool-aged children include a better understanding of the proportion of common refractive errors as well as their link with race/ethnicity. Screening criteria for more precise recognition of children who require intervention to prevent permanent vision loss can be informed by these data.
