Figure 2: Modified Bland-Altman plots of the mean difference of intraocular pressure measurement (mmHg) between Goldmann Applanation Tonometry and rebound tonometry.

Mean IOP differences on the three examination days were 0.15 mmHg; 95% confidence interval (CI): −0.50–0.80 mmHg; 95% limit of agreement (LoA): −6.83–7.12 mmHg (p = 0.682).
