Intraocular Pressure (IOP) was measured by Goldmann Applanation and Tono-Vera on 160 eyes of 160 subjects. Corneal Astigmatism and Central Corneal Thickness were also measured. A single investigator (CN) conducted all measurements. The average of two measurements from each tonometer was used in the analysis. Bland-Altman plots, total least squares regression analysis, and simple linear regression were used to evaluate agreement between the tonometers.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Average IOP values from Goldmann Applanation and Tono-Vera were not significantly different (19.17 and 19.03 respectively, p=0.40, paired t-test). The total least squares regression analysis indicated strong agreement between the two tonometers (slope +0.97, offset +0.49 mmHg, standard deviation 2.11 mmHg). There were 2 IOP measurement pairs that exceeded the \u00b1 5 mmHg limits of agreement required in ANSI Z80.10-2014 and ISO 8612-2009, which is within the range of acceptability specified in the standards.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>We evaluated IOP measurements by Tono-Vera Rebound Tonometer vs Goldmann Applanation Tonometry for eyes with a wide range of IOP values and found no statistically significant differences in the results. Tono-Vera meets the requirements of ANSI Z80.10-2014 and ISO 8612-2009, demonstrating accuracy comparable to Goldmann tonometry.<\/jats:p><\/jats:sec>","DOI":"10.3389\/fopht.2024.1441343","type":"journal-article","created":{"date-parts":[[2024,8,16]],"date-time":"2024-08-16T05:10:23Z","timestamp":1723785023000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":2,"title":["Evaluation of agreement of IOP measurements by Tono-Vera tonometer to Goldmann applanation tonometry"],"prefix":"10.3389","volume":"4","author":[{"given":"Charles R.","family":"Niles","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alexander R.","family":"Crinzi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Russell","family":"Bonaventura","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"David A.","family":"Taylor","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2024,8,16]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ophtha.2014.05.013","article-title":"Global prevalence of glaucoma and projections of glaucoma burden through 2040: a systematic review and meta-analysis","volume":"121","author":"Tham","year":"2014","journal-title":"Ophthalmology"},{"key":"B2","doi-asserted-by":"publisher","DOI":"10.1001\/archopht.120.6.701","article-title":"The Ocular Hypertension Treatment Study: a randomized trial determines that topical ocular hypotensive medication delays or prevents the onset of primary open-angle glaucoma","volume":"120","author":"Kass","year":"2002","journal-title":"Arch Ophthalmol"},{"key":"B3","doi-asserted-by":"publisher","first-page":"48","DOI":"10.1001\/archopht.121.1.48","article-title":"Factors for glaucoma progression and the effect of treatment: the early manifest glaucoma trial","volume":"121","author":"Leske","year":"2003","journal-title":"Arch Ophthalmol"},{"key":"B4","doi-asserted-by":"publisher","DOI":"10.1016\/S0002-9394(00)00538-9","article-title":"The Advanced Glaucoma Intervention Study (AGIS) 7.
