Based on the national vision screening guideline, the screening outcome was identified as: sufficient/insufficient/non-cooperative VAM, repeat examination or referral. Data analysis consisted of determining (1) non-cooperative and insufficient VAM rates at 45 m, (2) 45 m referral policy after insufficient and non-cooperative VAM, (3) 45 m outcome for non-cooperative or insufficient VAMActa ophthalmologica799-811https://www.ebi.ac.uk/biostudies/studies/S-EPMC12531601biostudies-literatureComparison of the effectiveness of visual acuity measurements for amblyopia screening at the age of 36 and 45 months and difference in severity of amblyopia detected.PMC12531601Kroon AHoolsema-Greving TBos JBoon LWestra-Postma IPeeters MAsjes Wde Graaf-Helfensteijn MVisser ESimonsz HJGutter MLieverse EVerheij GTelleman MAJDijkers ELoudon SESlot XVisser KHeuveling-Rijswijk MBenjamins SJde Graaf Avan Aggelen ISloot FOrthoptic Research Groupvan Dijk MBos-Koelewijn CSchouten JWijkmans CBoer RSchram-Rienstra DKok JTde Vries JSultanali Nvan Ketwich-Godfroy FArentzen Jvan Andel HHoekstra MAlteveer TEvers HSchoonenberg ALokhorst Lvan den Berg WBennen ASpek BScholten CSteenbergen Lvan Dijk Jde Jongh-van den Tweel MfalseComparison of the effectiveness of visual acuity measurements for amblyopia screening at the age of 36 and 45 months and difference in severity of amblyopia detected.<h4>Purpose</h4>Efficiency of visual screening using visual acuity measurement (VAM) in children screened at 45 months of age (45 m) and screened at both 36 months of age (36 m) and 45 m was investigated by determining failure, repeat and referral rates and amblyopia detection.<h4>Methods</h4>Data from Dutch screening records and treating orthoptists of 10 811 children born July 2011-June 2012 were analysed.
