Density histograms showing intraocular pressure (IOP) distributions in (A, B, C) control and (D, E, F) glaucoma groups. The mean IOP was significantly higher in the OAG group (14.4 ± 2.9 mmHg, range 7–22 mmHg) compared to the control group (13.9 ± 2.7 mmHg, range 6–21 mmHg, P = 0.022). However, no significant difference was found in separate analyses of men and women. SD = standard deviation; CI = confidence interval.
