To determine the repeatability and reliability, we applied intragrader agreement using the intraclass correlation coefficient (ICC). &lt;b&gt;&lt;i&gt;Results:&lt;\/i&gt;&lt;\/b&gt; Significant diurnal variation in CT was observed. The highest mean CT was found at 9 a.m. The lowest mean CT occurred at 1 p.m. There was excellent intragrader agreement, with the ICC ranging from 0.961 to 0.997. There was no significant diurnal variation in RT. &lt;b&gt;&lt;i&gt;Conclusion:&lt;\/i&gt;&lt;\/b&gt; There was significant diurnal variation in CT. The choroid was thinner at 1 p.m. than at 9 a.m. and 6 p.m.<\/jats:p>","DOI":"10.1159\/000375538","type":"journal-article","created":{"date-parts":[[2015,3,12]],"date-time":"2015-03-12T07:16:57Z","timestamp":1426144617000},"page":"192-197","source":"Crossref","is-referenced-by-count":21,"title":["Diurnal Variation in Choroidal and Retinal Thickness of the Early Treatment of Diabetic Retinopathy Study Macular Subfields Determined Using Swept-Source Optical Coherence Tomography"],"prefix":"10.1159","volume":"233","author":[{"given":"Yong-Seop","family":"Han","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hyung-Bin","family":"Lim","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Soo-Hyun","family":"Lee","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jung-Yeul","family":"Kim","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2015,3,12]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ophtha.2010.09.012"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ajo.2011.03.008"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1167\/iovs.08-3325"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1167\/iovs.10-6875"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1016\/j.ajo.2011.05.037"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.1097\/IAE.0b013e3181be0a83"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.1097\/IAE.0b013e3182083beb"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.1016\/j.ajo.2008.05.032"},{"key":"ref9","doi-asserted-by":"publisher","DOI":"10.1016\/j.ajo.2010.04.018"},{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.1016\/j.ophtha.2011.07.002"},{"key":"ref11","doi-asserted-by":"publisher","DOI":"10.3928\/23258160-20131101-08"},{"key":"ref12","doi-asserted-by":"publisher","DOI":"10.1016\/j.ophtha.2012.07.048"},{"key":"ref13","doi-asserted-by":"publisher","DOI":"10.1167\/iovs.11-8782"},{"key":"ref14","doi-asserted-by":"publisher","DOI":"10.1167\/iovs.11-8383"},{"key":"ref15","doi-asserted-by":"publisher","DOI":"10.1097\/IAE.0b013e3182993f29"},{"key":"ref16","doi-asserted-by":"publisher","DOI":"10.1167\/iovs.13-12350"},{"key":"ref17","doi-asserted-by":"publisher","DOI":"10.1016\/j.ophtha.2013.07.040"},{"key":"ref18","doi-asserted-by":"publisher","DOI":"10.1364\/OE.18.020029"},{"key":"ref19","doi-asserted-by":"publisher","DOI":"10.1364\/OE.15.006121"},{"key":"ref20","doi-asserted-by":"publisher","DOI":"10.1016\/j.ajo.2013.11.008"},{"key":"ref21","doi-asserted-by":"publisher","DOI":"10.1167\/iovs.10-6024"},{"key":"ref22","doi-asserted-by":"publisher","DOI":"10.1167\/iovs.11-8076"},{"key":"ref23","doi-asserted-by":"publisher","DOI":"10.1167\/iovs.11-8771"},{"key":"ref24","doi-asserted-by":"publisher","DOI":"10.1167\/iovs.11-8836"},{"key":"ref25","doi-asserted-by":"publisher","DOI":"10.1167\/iovs.10-6811"},{"key":"ref26","doi-asserted-by":"publisher","DOI":"10.1167\/iovs.13-13135"},{"key":"ref27","doi-asserted-by":"publisher","DOI":"10.1167\/iovs.11-7729"},{"key":"ref28","doi-asserted-by":"publisher","DOI":"10.1016\/j.ophtha.2011.10.029"},{"key":"ref29","doi-asserted-by":"publisher","DOI":"10.1167\/iovs.12-9435"},{"key":"ref30","doi-asserted-by":"publisher","DOI":"10.1167\/iovs.11-7403"}],"container-title":["Ophthalmologica"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/375538","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/375538","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,23]],"date-time":"2025-04-23T17:43:46Z","timestamp":1745430226000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000375538"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2015]]},"references-count":30,"journal-issue":{"issue":"3-4","published-online":{"date-parts":[[2015,6,1]]},"published-print":{"date-parts":[[2015,6,11]]}},"URL":"https:\/\/doi.org\/10.1159\/000375538","archive":["Portico"],"relation":{},"ISSN":["0030-3755","1423-0267"],"issn-type":[{"value":"0030-3755","type":"print"},{"value":"1423-0267","type":"electronic"}],"subject":[],"published":{"date-parts":[[2015]]}}}
