Evaluation of the New Digital Goldmann Applanation Tonometer for Measuring Intraocular Pressure
Figure 3
Bland-Altman plot of mean intraocular pressure (IOP) based on standard Goldmann applanation tonometry (sGAT) and digital Goldmann applanation tonometry (dGAT). The mean difference (sGAT-dGAT) was –0.09 mmHg. The 95% confidence interval (mean difference ± 1.96 SD) ranged from –0.95 mmHg to +0.77 mmHg () as shown by broad lines in the graph.
