The offset index was calculated as the distance of the CRVT from the BMO center relative to that of the BMO margin. The angular deviation of CRVT was measured with the horizontal nasal midline as 0\u00b0 and the superior location as a positive value. The offset index and angular deviation were compared between glaucoma and fellow control eyes within individuals.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"sec003\">\n<jats:title>Results<\/jats:title>\n<jats:p>NTG eyes had higher baseline intraocular pressure (<jats:italic>P<\/jats:italic> = 0.001), a larger \u03b2-zone parapapillary atrophy area (<jats:italic>P<\/jats:italic> = 0.013), and a larger offset index (<jats:italic>P<\/jats:italic>&lt;0.001). In a generalized linear mixed-effects model, larger offset index was the only risk factor of NTG diagnosis (OR = 31.625, <jats:italic>P<\/jats:italic>&lt;0.001). A generalized estimating equation regression model revealed that the offset index was larger in the NTG eyes than in the control eyes for all ranges of axial length, while it was the smallest for the axial length of 23.4 mm (all <jats:italic>P<\/jats:italic>&lt;0.001).<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"sec004\">\n<jats:title>Conclusions<\/jats:title>\n<jats:p>The offset index was larger in the unilateral NTG eyes, which fact is suggestive of the potential role of LC\/BMO offset as a loco-regional susceptibility factor.<\/jats:p>\n<\/jats:sec>","DOI":"10.1371\/journal.pone.0254889","type":"journal-article","created":{"date-parts":[[2021,7,20]],"date-time":"2021-07-20T17:22:21Z","timestamp":1626801741000},"page":"e0254889","update-policy":"https:\/\/doi.org\/10.1371\/journal.pone.corrections_policy","source":"Crossref","is-referenced-by-count":8,"title":["Central retinal vascular trunk deviation in unilateral normal-tension glaucoma"],"prefix":"10.1371","volume":"16","author":[{"given":"Ho-Kyung","family":"Choung","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Martha","family":"Kim","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3010-448X","authenticated-orcid":true,"given":"Sohee","family":"Oh","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4692-3164","authenticated-orcid":true,"given":"Kyoung Min","family":"Lee","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Seok Hwan","family":"Kim","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"340","published-online":{"date-parts":[[2021,7,20]]},"reference":[{"issue":"18","key":"pone.0254889.ref001","doi-asserted-by":"crossref","first-page":"1901","DOI":"10.1001\/jama.2014.3192","article-title":"The pathophysiology and treatment of glaucoma: a review","volume":"311","author":"RN Weinreb","year":"2014","journal-title":"Jama"},{"issue":"2","key":"pone.0254889.ref002","doi-asserted-by":"crossref","first-page":"120","DOI":"10.1016\/j.exer.2010.09.005","article-title":"A biomechanical paradigm for axonal insult within the optic nerve head in aging and glaucoma","volume":"93","author":"CF Burgoyne","year":"2011","journal-title":"Exp Eye Res"},{"issue":"9774","key":"pone.0254889.ref003","doi-asserted-by":"crossref","first-page":"1367","DOI":"10.1016\/S0140-6736(10)61423-7","article-title":"Glaucoma","volume":"377","author":"HA Quigley","year":"2011","journal-title":"Lancet"},{"issue":"4","key":"pone.0254889.ref004","doi-asserted-by":"crossref","first-page":"635","DOI":"10.1001\/archopht.1981.03930010635009","article-title":"Optic nerve damage in human glaucoma.
