In the same time, high refractive errors, a common complication in ROP cases and especially in ROP treated infants, have become the main cause of visual and often severe visual impairment.\r\nAIM: The purpose of our study was to analyse the long-term refractive status in children at 3.5 years after laser-treatment for type 1 prethreshold ROP.\r\nPATIENTS AND METHODS: A retrospective, one centre study of refractive status of 18 children with laser-treated type 1 prethreshold ROP was conducted. The refraction after cycloplegia with 1% cyclopentolate was measured at a mean age of 3.56 years (SD \u00b1 0.34). Hyperopia was subdivided into two groups \u2013 low hyperopia (SE &lt; +5.0 D) and high hyperopia (SE \u2265 +5.0 D). Myopia was classified as myopia (SE \u2265 \u20130.25D) and high myopia (SE \u2265 -5.0 D). Astigmatism was divided into low astigmatism (plus CD \u2265 +1.0 D) and high astigmatism (plus CD \u2265 +2.0 D).\r\nRESULTS: Thirty-three eyes of 18 children were recruited in the study. Three eyes were excluded because of unfavourable anatomical results. The mean gestational age at birth was 27.3 weeks (24-31 weeks, SD \u00b1 1.78), and the mean birth weight \u2013 928.9 g (550-1500 g, SD \u00b1 252.8). The mean spherical equivalent for the whole group was -1.82 D and ranged from -9.00 D to +4.50 D (SD \u00b1 3.48). Hyperopia was observed in 12 (36.4%) eyes. Myopic refraction had 21 (63.6%) eyes. Astigmatism was detected in 18 (54.5%) eyes. Anisometropia had 3 (16.7%) children. Six children (33.4%) had strabismus (4 esotropia; 2 exotropia).\r\nCONCLUSION: High per cent of treated infants for vision-threatening ROP have visual significant refractive errors and strabismus that can cause serious visual impairment if not treated properly and on time.<\/jats:p>","DOI":"10.3889\/oamjms.2019.309","type":"journal-article","created":{"date-parts":[[2019,5,6]],"date-time":"2019-05-06T17:27:35Z","timestamp":1557163655000},"page":"1320-1323","source":"Crossref","is-referenced-by-count":1,"title":["Refractive Status in Children with Laser-Treated Retinopathy of Prematurity: Our Experience in Bulgaria"],"prefix":"10.3889","volume":"7","author":[{"given":"Nevyana","family":"Veleva","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Violeta","family":"Chernodrinska","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"52292","published-online":{"date-parts":[[2019,4,30]]},"container-title":["Open Access Macedonian Journal of Medical Sciences"],"original-title":[],"link":[{"URL":"https:\/\/spiroski.migration.publicknowledgeproject.org\/index.php\/mjms\/article\/download\/oamjms.2019.309\/3277","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/oamjms.eu\/index.php\/mjms\/article\/download\/oamjms.2019.309\/3255","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,4,19]],"date-time":"2023-04-19T21:30:20Z","timestamp":1681939820000},"score":1,"resource":{"primary":{"URL":"https:\/\/spiroski.migration.publicknowledgeproject.org\/index.php\/mjms\/article\/view\/oamjms.2019.309"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2019,4,30]]},"references-count":0,"journal-issue":{"issue":"8","published-online":{"date-parts":[[2019,4,30]]}},"URL":"https:\/\/doi.org\/10.3889\/oamjms.2019.309","relation":{},"ISSN":["1857-9655"],"issn-type":[{"type":"electronic","value":"1857-9655"}],"subject":[],"published":{"date-parts":[[2019,4,30]]}}}
