[Ambulatory 24-h blood pressure measurement in patients with glaucoma]

The arterial blood pressure is an important determinant for the development and progression of glaucoma. Some relevant information can be obtained only by ambulatory 24-h blood pressure measurement (ABPM). White-coat hypertension can be excluded by ABDM and the variability of blood pressure during 24 hours can be assessed. 24-h mean blood pressure should be < 130/80 mmHg. In contrast, diastolic blood pressure values below 60 mmHg during the night have been identified as a progression factor in glaucoma, as well as reductions of night-time systolic blood pressure of less than 10 % (non-dipper) and of more than 20 % (extreme dipper). The significance of the 24-h blood pressure profile for the cooperation of ophthalmology and internal medicine is discussed.
