Abstract: PURPOSE: To 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. METHODS: 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 < 10%, and dipper when this value was higher. RESULTS: 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. CONCLUSION: 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.
