One randomised eye of each participant was selected for this report\u2019s analysis. A Bland\u2013Altman plot was used to compare the values obtained with the two devices.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The correlation between rebound tonometer and Goldmann applanation tonometer was good: the intraclass correlation coefficient (r) between the two methods was 0.735 ( p\u2009&lt;\u20090.001). The mean difference (rebound tonometer\u2013Goldmann applanation tonometer) was 0.11\u2009\u00b1\u20092.3\u2009mmHg. The difference was not statistically significant (95% confidence interval: 0.11 to 0.13, p\u2009=\u20090.09). With increasing central corneal thickness, not only did intraocular pressure values with both devices increase, but the difference between them also increased. Refraction (spherical equivalent) did not influence intraocular pressure or the rebound tonometer\u2013Goldmann applanation tonometer difference. However, high astigmatism (\u22652D) exerted an influence on intraocular pressure values taken with Goldmann applanation tonometer.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Measurements with rebound tonometer and Goldmann applanation tonometer are relatively uniform although rebound tonometer slightly overestimated intraocular pressure. Both rebound tonometer and Goldmann applanation tonometer and the difference between these devices were affected by central corneal thickness but not by refraction. Higher astigmatism affected Goldmann applanation tonometer more than rebound tonometer. It is concluded that rebound tonometer is a reliable method for measuring intraocular pressure in a population-based screening study.<\/jats:p>\n
