We also made a comparison between each of the three techniques.<\/p><p><strong>Methods:&nbsp;<\/strong>We performed our study on 66 eyes (66 patients) with ONHD and 70 healthy control subjects (70 controls) with colour ocular fundus photography at 20\u00ba (Zeiss FF 450 IR plus), TD-OCT (Stratus OCT) with the Fast Optic Disc protocol and SD-OCT (Cirrus OCT) with the Optic Disc Cube 200 \u00d7 200 protocol for measurement of the optic disc area. The measurements were made by two observers and in each measurement a correction of the image magnification factor was performed. Measurement comparison using the Student&#8217;s t-test\/Mann-Whitney U test, the intraclass correlation coefficient, Pearson\/Spearman rank correlation coefficient and the Bland-Altman plot was performed in the statistical analysis.<\/p><p><strong>Results:&nbsp;<\/strong>Mean and standard deviation (SD) of the optic disc area in ONHD and in controls was 2.38 (0.54) mm(2) and 2.54 (0.42) mm(2), respectively with fundus photography; 2.01 (0.56) mm(2) and 1.66 (0.37) mm(2), respectively with TD-OCT, and 2.03 (0.49) mm(2) and 1.75 (0.38) mm(2), respectively with SD-OCT. In ONHD and controls, repeatability of optic disc area measurement was excellent with fundus photography and optical coherence tomography (TD-OCT and SD-OCT), but with a low degree of agreement between both techniques.<\/p><p><strong>Conclusions:&nbsp;<\/strong>Optic disc area measurement is smaller in ONHD compared to healthy subjects with fundus photography, unlike time-domain and spectral-domain optical coherence tomography in which the reverse is true. Both techniques offer good repeatability, but a low degree of correlation and agreement, which means that optic disc area measurement is not interchangeable or comparable between techniques.<\/p><p id=\"copyright\">Ophthalmic &amp; Physiological Optics \u00a9 2013 The College of Optometrists.<\/p>","protected":false},"excerpt":{"rendered":"<p>https:\/\/pubmed.ncbi.nlm.nih.gov\/23311663\/ Flores-Rodr\u00edguez P, Gili P, Mart\u00edn R\u00edos M, Grifol-Clar E Ophthalmic and Physiological Optics 2013; 33:164-71 Abstract Purpose:&nbsp;To compare optic [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":3407,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"om_disable_all_campaigns":false,"_monsterinsights_skip_tracking":false,"_monsterinsights_sitenote_active":false,"_monsterinsights_sitenote_note":"","_monsterinsights_sitenote_category":0,"footnotes":""},"categories":[20],"tags":[25,26],"class_list":["post-187","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-peerreview","tag-direction","tag-vision-goal-setting"],"aioseo_notices":[],"_links":{"self":[{"href":"https:\/\/cvpf.cl\/academy\/wp-json\/wp\/v2\/posts\/187","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/cvpf.cl\/academy\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/cvpf.cl\/academy\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/cvpf.cl\/academy\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/cvpf.cl\/academy\/wp-json\/wp\/v2\/comments?post=187"}],"version-history":[{"count":2,"href":"https:\/\/cvpf.cl\/academy\/wp-json\/wp\/v2\/posts\/187\/revisions"}],"predecessor-version":[{"id":3490,"href":"https:\/\/cvpf.cl\/academy\/wp-json\/wp\/v2\/posts\/187\/revisions\/3490"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/cvpf.cl\/academy\/wp-json\/wp\/v2\/media\/3407"}],"wp:attachment":[{"href":"https:\/\/cvpf.cl\/academy\/wp-json\/wp\/v2\/media?parent=187"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/cvpf.cl\/academy\/wp-json\/wp\/v2\/categories?post=187"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/cvpf.cl\/academy\/wp-json\/wp\/v2\/tags?post=187"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
