A comparison of 24-hour IOP patterns for the OHTN (open circles), healthy control (open triangles), and glaucoma (solid squares) groups in the habitual position (diurnal sitting, nocturnal supine). The OHTN group consisted of 15 untreated 41- to 77-year-old patients with IOP > 21 mm Hg on two consecutive visits and no evidence of glaucomatous changes. This group was compared with an age-matched control group with healthy eyes (n = 24) and an untreated glaucoma group (n = 24). Error bars denote SEM.
