Asmussen A, Smith BS, Møller F, et al. - Utilizing swept-source optical coherence tomography (SS-OCT), researchers estimated repeatability and inter-observer variation of choroidal thickness measurements in myopic Danish children aged 7–14 years. The sample consisted of 39 children. In this paediatric population, the 3D macula scan method was the most repeatable method. It produced a coefficients of repeatability (CR) of 10.7 µm, confidence interval 2.4 µm, resulting in a minimal detectable difference between two measurements 13.1 µm. The intramethod variation could explain the majority of the interobserver variation. On a group level, segmentation adjustment on 3D macula scans did not increase CR.
