To identify in patients with branch retinal vein occlusion using ambulatory blood pressure monitoring and clinical blood pressure measures: hypertension prevalence, and diurnal pattern of blood pressure.Design and Method:
Retrospectively, 47 patients with branch retinal vein occlusion were submitted to clinical evaluation and ambulatory blood pressure monitoring. Non-dipper was defined as a fall in systolic blood pressure ≤ 10%, and dipper when this value was higher.Results:
Fifteen (31.9 %) patients were diagnosed as hypertensive after office blood pressure measurement. Ambulatory blood pressure monitoring identified 13 hypertensives, 15 normotensives, 2 white-coat hypertensive and 17 masked hypertensive subjects.Results:
Among 13 hypertensive and 17 masked hypertensive subjects, 7 (23.3 %) were dippers and 23 (76.6 %) were non-dippers.Conclusions:
Prevalence of masked hypertension in patients with branch retinal vein occlusion was high (64%) and more than two-thirds of hypertensive patients were non-dippers.Conclusions:
These evidences suggest that ambulatory blood pressure monitor may be essential examination for patient with branch retinal vein occlusion.
