In the preterm group, 29 children had had retinopathy of prematurity (ROP) and nine children had neurological complications. The optic nerve head was assessed with HRT. Three measurements were performed, and the different topographic parameters were noted.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Rim area of the optic nerve was significantly smaller in prematurely born children than in children born at term. The mean difference was 0.146\u00a0mm<jats:sup>2<\/jats:sup> (p\u00a0=\u00a00.02). No difference between the groups was found regarding disc area or cup area. In the preterm group, both disc and rim areas were reduced with increasing GA. No correlations with birthweight, ROP or neurological complications were found.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Reduced rim area of the optic nerve head was found in preterm children of school age. Previous ROP or neurological complication did not influence the result, suggesting the preterm birth per se was the reason for the reduction. Establishing whether this finding was caused by disturbed maturation of the optic nerve or by injury of the axons, or a combination of the two, will require further research.<\/jats:p><\/jats:sec>","DOI":"10.1111\/aos.13785","type":"journal-article","created":{"date-parts":[[2018,9,16]],"date-time":"2018-09-16T12:57:04Z","timestamp":1537102624000},"page":"699-704","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["The rim area of the optic nerve head, assessed with Heidelberg retina tomography, is smaller in prematurely born children than in children born at term"],"prefix":"10.1111","volume":"96","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4041-8482","authenticated-orcid":false,"given":"Hanna","family":"\u00c5kerblom","sequence":"first","affiliation":[{"name":"Department of Neuroscience\/Ophthalmology Uppsala University Uppsala Sweden"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5600-7186","authenticated-orcid":false,"given":"Gerd","family":"Holmstr\u00f6m","sequence":"additional","affiliation":[{"name":"Department of Neuroscience\/Ophthalmology Uppsala University Uppsala Sweden"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9674-0094","authenticated-orcid":false,"given":"Eva","family":"Larsson","sequence":"additional","affiliation":[{"name":"Department of Neuroscience\/Ophthalmology Uppsala University Uppsala Sweden"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2018,9,14]]},"reference":[{"key":"e_1_2_5_2_1","doi-asserted-by":"publisher","DOI":"10.1136\/bjo.2010.184747"},{"key":"e_1_2_5_3_1","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0088056"},{"key":"e_1_2_5_4_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1651-2227.2010.01846.x"},{"key":"e_1_2_5_5_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1755-3768.1978.tb01369.x"},{"key":"e_1_2_5_6_1","doi-asserted-by":"publisher","DOI":"10.1136\/bjophthalmol-2012-302066"},{"key":"e_1_2_5_7_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1755-3768.2008.01365.x"},{"key":"e_1_2_5_8_1","first-page":"1184","article-title":"Ocular fundus morphology in preterm children.
