Abstract AIMThe aim of the present study was to characterize the rhythm of 24-h intraocular pressure (IOP) and ocular perfusion pressure (OPP) in patients with ocular hypertension (OHTN), in order to provide a reference for the clinical diagnosis and treatment of OHTN. METHODSAccording to the diagnostic criteria, 107 patients with OHTN were included, and an age- and sex-matched healthy control group (71 patients) was selected. The IOP and blood pressure (BP) of the OHTN and the healthy control groups were recorded every 2 h over a 24-h period. BP was measured using a digital automatic BP monitor, and IOP was measured using a non-contact tonometer. RESULTSThe maximum, minimum and mean IOP were significantly higher in subjects with OHTN than in the healthy control group (P<0.05), and the maximum, minimum and mean MOPP were significantly lower in the OHTN group than in the healthy control group (P<0.05). The minimum and mean SOPP and DOPP values of the OHTN group were lower than those of the healthy control group (P<0.05), and the IOP, MOPP, SOPP and DOPP diurnal and nocturnal fluctuation values were significantly greater in the OHTN group than in the healthy control group (P<0.05). The peak and trough IOP times of the two groups coincided, which tended to be low during the day and higher at night. The peak and trough MOPP and SOPP times of the two groups also coincided, and were primarily higher during the day and lower at night. The 24-h DOPP in the healthy control group was generally higher during the daytime and lower at night, with peak values between 19:00-23:00 h, and trough values between 3:00-7:00 h. No obvious day-to-night fluctuations were observed in the OHTN group. CONCLUSIONThe OPP of patients with OHTN is lower, and the 24-h OPP fluctuates more than that of healthy control subjects. This may be an important blood flow factor for the progression to primary open angle glaucoma in patients with OHTN.

Pseudoexfoliation syndrome (PEX) is a relatively widespread generalized age-related disease, in which abnormal fibrillar extracellular material is produced and accumulates in many tissues. It seems reasonable to evaluate ocular pulse amplitude in patients with PEX. Purpose. To evaluate ocular pulse amplitude in patients with PEX. Methods. 460 eyes of 230 patients were enrolled in the prospective study. We evaluated ocular pulse amplitude and perfusion pressure. Results. Difference in perfusion pressure between groups was not significant. Ocular pulse amplitude was significantly lower in patients with PEX. Conclusion. Ocular pulse amplitude decrease indicates damage of ocular blood flow.
