Vision Screening in Children Aged 6 Months to 5 Years

“…A total of 40 published studies (described in 46 articles) with 34 709 participants were included (Figure 2). The main results for each KQ are summarized below.…”

“…Thirty-four fair-quality studies (described in 38 articles) were included (eTables 6-17 in the Supplement). The studies evaluated a variety of test types, including visual acuity tests, stereoacuity tests, ocular alignment tests, autorefractors, photoscreeners, and retinal birefringence scanning. Screening was administered by a variety of personnel across studies (eg, pediatricians, ophthalmologists, nurses, research staff).…”

“…Findings from the Vision In Preschoolers (VIP) study, the largest study for this KQ, were reported in multiple manuscripts (up to 4040 participants) . Phase 1 of the VIP study enrolled 3- to 5-year-olds and compared the accuracy of 11 screening tests .…”

“…Sixteen fair-quality studies (16 712 observations) evaluated autorefractors (eTables 6-17 in the Supplement). Overall, most studies found moderate positive LRs and small negative LRs, although some found large positive and negative LRs.…”

“…One controlled study that evaluated potential psychosocial effects was included, and 16 studies of test accuracy described in KQ2 were used to calculate false-positive rates . The controlled study used the ALSPAC population-based cohort (n = 4473) to assess bullying by age 8 years .…”
