Optical correction was single\u2010vision spectacles (SVS) or orthokeratology lenses (OKL). Three repeated 7\u2009\u00d7\u20097 mm 3\u2010dimensional SS\u2010OCT macula scans and three repeated 9\u2009mm SS\u2010OCT line scans\u2009were collected for each child using a DRI OCT\u2009Triton. Choroidal thickness was measured using three different methods: line scan method 1 (LM1), line scan method 2 (LM2) and 3D macula scan method (3DM). Segmentation was adjusted if needed. Coefficients of repeatability (CR) and limits of agreement (LoA) were calculated.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The CRs ranged from 13.4 to 23.9\u2009\u00b5m, 14.5 to 26.2\u2009\u00b5m and 5.2 to 10.7\u2009\u00b5m for LM1, LM2 and 3DM, respectively.\u2009The\u2009LoA\u2009ranged from \u221222.9 to +31.5\u2009\u00b5m, \u221223.3 to +32.2\u2009\u00b5m and \u221210.2 to +12.4\u2009\u00b5m for LM1, LM2 and 3DM, respectively.\u2009Segmentation was adjusted in most\u2009scans (63%\u201392%).\u2009Mean choroidal thickness ranged from 142.2\u2009\u00b1\u200947.2 to 253.8\u2009\u00b1\u200960.9\u2009\u00b5m and 190.1\u2009\u00b1\u200964.0 to 299.0\u2009\u00b1\u200955.8\u2009\u00b5m for the SVS and OKL groups, respectively, measured by 3DM.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>The 3DM was the most repeatable method in this paediatric population. It yielded a CR of 10.7\u2009\u00b5m, confidence interval 2.4\u2009\u00b5m, which makes the minimal detectable difference between two measurements 13.1\u2009\u00b5m. Most inter\u2010observer variation could be explained by the\u2009intramethod\u2009variation.\u2009Segmentation adjustment on 3D macula scans did not increase CR on a group level.<\/jats:p>\n
