Abstract Details

Purpose:

To determine the differences in the diurnal blood pressure (BP) of patients with normotensive glaucoma (NTG), primary open angle glaucoma (POAG), and controls without glaucoma.

Setting:

Adnan Menderes University, Department of Ophthalmology and Department of Cardiology, Aydin, Turkey

Methods:

A total of 129 patients, including 43 NTG patients (Group 1), 44 POAG patients (Group 2), and 42 healthy subjects without glaucoma (Group 3), were included in this study. The day-night average systolic and diastolic BPs, the day-night average pulse pressures (PPs), the day-night average heart rates, and the percentage the BP declined at night was obtained from the Holter devices and compared.

Results:

The average day and night PP values of Group 1 were 49.17±9.90 and 46.07±10.84, respectively, their total average PP was 48.48±9.60, their total average systolic BP was 120.02±12.65, and their night average systolic BP was 111.93±15.87. In Group 2, the average day and night PP values were 54.83±10.35 and 51.73±9.10, respectively, their total average PP was 54.00±9.87, their total average systolic BP was 126.75±11.50, and their night average systolic BP was 119.21±12:38. These differences were statistically significant, and the corresponding P values were 0.040, 0.040, 0.037, 0.033, and 0.038, respectively.

Conclusions:

NTG patients have low diurnal BP parameters, which may reduce their optic nerve perfusion and may be responsible for their glaucomatous visual field damage.
