ResumoTo identify in patients with branch retinal vein occlusion using ambulatory blood pressure monitoring and clinical blood pressure measures: hypertension prevalence, and nocturnal profile of blood pressure.Prospectively, 93 eyes of 83 patients with branch retinal vein occlusion were submitted to ophthalmological examination. Afterwards the patients were submitted to clinical evaluation and blood pressure monitoring. Non-dipper was defined as a fall in systolic blood pressure <or= 10%, and dipper when this value was higher.Disease affected one eye in 73 (88%) patients. The temporal superior branch was the site of occlusion in 61 (65.6%) eyes, while in the others the infero-temporal branch was affected. Seventy six (92%) patients were diagnosed as hypertensive after clinical evaluation. Ambulatory blood pressure monitoring identified 76 hipertensives, 5 normotensives, 1 white-coat hypertensive and one masked hypertensive subjects. The two latter were excluded from the analysis. Of the 81 analyzed patients, forty (49%) were dippers and 41 (51%) were non-dippers. Among the HT (n=76), 36 (47%) were dippers and 40 (53%) were non-dippers.Prevalence of hypertension in our series was extremely high (92%) which suggests that physiopathology of the disease has a close relationship with changes promoted by hypertension. A little more than half of the hypertensives were non-dippers (n=40; 52,6%). These evidences suggest that a 24-hour sustained level of blood pressure may be an additional risk factor for branch retinal vein occlusion.
