To provide population-based normative data for monocular visual acuity (VA) and interocular differences in VA (IOD) Black Hispanic children 30 to 72 months of age without visually significant refractive errors or ophthalmic abnormalities.In a cohort the Multi-Ethnic Pediatric Eye Disease Study, HOTV measurements using Amblyopia Treatment Study protocol were analyzed continuous dichotomous outcomes IOD, after excluding subjects with abnormalities error.The analysis consisted 1722 aged months. Mean logMAR improved (p < 0.0001) male gender = 0.0008). The proportion achieving 20/40 better was associated 0.0001), but not ethnicity gender, 81, 94, 99, virtually 100% 35, 36 47, 48 59, 60 age, respectively. most stringent threshold that excluded <5% normal 20/63, 20/50, 20/32, 20/32 months, Children attending preschool daycare achieved more often than those attending, adjustment 0.01), as did from higher-income families 0.04). There no association between mean absolute IOD 0.45), 0.12), 0.19). an 0 1 lines higher males females 0.02); it vary by 0.06) 0.17).
