Methods: This retrospective\ncross-sectional study included 353 eyes from healthy individuals, glaucoma suspects, ocular hypertensive\npatients, and patients with glaucoma. Optic nerve head parameters\u2014including disc area, vertical and\narea cup-to-disc ratios, and rim volume\u2014were measured using swept-source optical coherence tomography\nand Laguna ONhE. Agreement between methods was assessed using Bland\u2013Altman analysis. A\nregression-based calibration model was developed for disc area measurements. Results: Laguna ONhE\nsystematically underestimated disc area (p &lt; 0.001) and cup-to-disc ratios (p&lt;0.001) and overestimated\nrim volume (p=0.0002) compared with swept-source optical coherence tomography. After applying the\ncalibration equation for disc area, agreement improved substantially, with no statistically significant bias\n(p=0.3). Conclusion: Laguna ONhE provides structural estimates comparable with those obtained with\nswept-source optical coherence tomography after calibration, suggesting it may serve as a practical and\ncost-effective alternative for glaucoma evaluation.<\/jats:p>","DOI":"10.5935\/0004-2749.2025-0377","type":"journal-article","created":{"date-parts":[[2026,8,14]],"date-time":"2026-08-14T20:25:10Z","timestamp":1786739110000},"page":"1-9","source":"Crossref","is-referenced-by-count":0,"title":["Agreement between structural parameters provided by the swept-source OCT and Laguna ONhE"],"prefix":"10.5935","volume":"89","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4982-8859","authenticated-orcid":false,"given":"Gilvan Vilarinho","family":"da Silva Filho","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4281-366X","authenticated-orcid":false,"given":"Gustavo Coelho","family":"Caiado","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0152-4231","authenticated-orcid":false,"given":"Ol\u00edvia Moura de Paula","family":"Ricardo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0000-6512-829X","authenticated-orcid":false,"given":"Sergio Henrique","family":"Teixeira","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1830-3766","authenticated-orcid":false,"given":"Tiago dos Santos","family":"Prata","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5086-9060","authenticated-orcid":false,"given":"Carolina Pelegrini Barbosa","family":"Gracitelli","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6266-6922","authenticated-orcid":false,"given":"Augusto","family":"Paranhos Jr","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"3948","published-online":{"date-parts":[[2026]]},"container-title":["Arquivos Brasileiros de Oftalmologia"],"original-title":[],"link":[{"URL":"https:\/\/www.scielo.br\/j\/abo\/a\/NBx3KsDqW7rJnxbD6xgJ6yy\/?lang=en&ilang=en","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,8,14]],"date-time":"2026-08-14T20:25:10Z","timestamp":1786739110000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.scielo.br\/j\/abo\/a\/NBx3KsDqW7rJnxbD6xgJ6yy\/?lang=en&ilang=en"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026]]},"references-count":0,"journal-issue":{"issue":"5","published-online":{"date-parts":[[2026]]},"published-print":{"date-parts":[[2026]]}},"URL":"https:\/\/doi.org\/10.5935\/0004-2749.2025-0377","relation":{},"ISSN":["0004-2749"],"issn-type":[{"value":"0004-2749","type":"print"}],"subject":[],"published":{"date-parts":[[2026]]}}}
