Referral criteria for further ophthalmological examination included a VA of \u22650.2 logMAR on the worse\u2010seeing eye or an interocular VA difference of \u22652 lines.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Initial screening identified amblyopia (defined as VA of \u22650.3 logMAR) in 7% (unilateral) and 3% (bilateral) of children. However, subsequent ophthalmological examinations confirmed amblyopia in under 40% of referrals. Significant interocular VA differences were found in 9%. The prevalence of refractive errors at the screening was 3% for myopia (\u2264\u22120.5 dioptres), 10% for hyperopia (&gt;+2.0 dioptres) and 14% for astigmatism (\u2264\u22121.00 dioptres), while the corresponding prevalences at the ophthalmological examination were 4% for myopia, 8% for hyperopia and 6% for astigmatism. Combining screening measurements increased the positive predictive values, thereby enhancing screening accuracy. Specifically, the incorporation of autorefraction or stereoacuity with distance VA demonstrated to be the most effective combination. Six percent of the children were prescribed glasses after the screening procedure.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>This study provides the first visual profile of Greenlandic schoolchildren. Incorporating autorefraction, stereoacuity and near visual acuity in vision screenings enhanced the efficacy of detection of vision anomalies. Although this may lead to more false positives, accurate screening is crucial in regions with limited ophthalmological resources.<\/jats:p><\/jats:sec>","DOI":"10.1111\/aos.16740","type":"journal-article","created":{"date-parts":[[2024,7,15]],"date-time":"2024-07-15T04:43:47Z","timestamp":1721018627000},"page":"162-170","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Vision screening and refraction of Greenlandic schoolchildren"],"prefix":"10.1111","volume":"103","author":[{"ORCID":"https:\/\/orcid.org\/0009-0004-7218-2111","authenticated-orcid":false,"given":"Nick","family":"Duelund","sequence":"first","affiliation":[{"name":"Queen Ingrids Healthcare Center  Nuuk Greenland"},{"name":"Greenland Center of Health Research, Institute of Health and Nature Ilisimatusarfik University of Greenland  Nuuk Greenland"},{"name":"Department of Ophthalmology Rigshospitalet  Copenhagen Denmark"},{"name":"University of Copenhagen  Copenhagen Denmark"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1680-4949","authenticated-orcid":false,"given":"Ivan","family":"Nisted","sequence":"additional","affiliation":[{"name":"Danish College of Optometry and Vision Science Dania Academy  Randers Denmark"},{"name":"Department of Clinical Medicine Aarhus University  Aarhus Denmark"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marit Eika","family":"J\u00f8rgensen","sequence":"additional","affiliation":[{"name":"Greenland Center of Health Research, Institute of Health and Nature Ilisimatusarfik University of Greenland  Nuuk Greenland"},{"name":"Steno Diabetes Center Greenland  Nuuk Greenland"},{"name":"University of Southern Denmark  Odense Denmark"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5906-7670","authenticated-orcid":false,"given":"Steffen","family":"Heegaard","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology Rigshospitalet  Copenhagen Denmark"},{"name":"University of Copenhagen  Copenhagen Denmark"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hanne","family":"Jensen","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology Rigshospitalet  Copenhagen Denmark"},{"name":"University of Copenhagen  Copenhagen Denmark"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2024,7,14]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.1080\/22423982.2020.1721983"},{"key":"e_1_2_9_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jaapos.2022.10.006"},{"key":"e_1_2_9_4_1","doi-asserted-by":"publisher","DOI":"10.3389\/fnins.2022.993826"},{"key":"e_1_2_9_5_1","doi-asserted-by":"publisher","DOI":"10.1097\/OPX.0000000000001972"},{"key":"e_1_2_9_6_1","unstructured":"Danish Health Authority.
