“…In the ophthalmic field, several studies have investigated the patterns of ABPM in patients with BRVO 17 – 19 . In a previous study, a higher prevalence of hypertension was observed in patients with BRVO, and approximately half of the patients with hypertension were non-dippers 19 . RVO studies in North America have suggested that 24-h ABPM is a useful tool for detecting uncontrolled nocturnal hypertension, and patients with RVO have a higher prevalence of non-dipping patterns 17 , 18 .…”

Branch retinal vein occlusion (BRVO) is ocular vascular disease affecting approximately 14 million people worldwide, and is closely associated with high blood pressure (BP). Although macular ischemia is a critical factor in the visual prognosis of BRVO, the relationship between macular ischemia and different patterns of nocturnal BP is unknown. Here, we investigated whether a dipping pattern of nocturnal BP is associated with the development of macular ischemia in patients with BRVO. A total of 273 patients were reviewed; of these, 86 (86 eyes) patients were included. All recruited patients had a macular thickness map by optical coherence tomography and underwent 24-h ambulatory BP monitoring. According to their dipping patterns, the participants were divided into dipper and non-dipper groups. The non-dipper group had worse visual outcomes at the initial and 6-month visits (P = 0.014 and P = 0.003, respectively). Five of 32 eyes (15.6%) in the dipper group and 32 of 54 (59.3%) in the non-dipper group had macular ischemia. In a multivariate analysis, the night-to-day systolic BP ratio was associated with the degree of macular ischemia (β = − 0.313, P = 0.004). Thus, a non-dipping pattern may be a risk factor for macular ischemia in patients with BRVO.

Purpose Failure of blood pressure (BP) to dip during sleep (non-dipper pattern) is associated with cardiovascular disease (CVD) and stroke. The prevalence and degree of non-dipping and masked hypertension in patients with retinal vein occlusion (RVO), which is associated with stroke, has not been previously examined. Methods We measured clinic and 24-hour ambulatory BPs in 22 patients with RVO and 20 control participants without known eye disease matched by age and sex. Mean BP dipping, defined as the ratio of difference in mean awake and sleep systolic BPs to mean awake systolic BP, and masked and nocturnal hypertension were compared between groups. Results Mean 24-hour ambulatory BP was 144/79 mmHg among those with RVO and 136/77 mmHg among controls. Patients with RVO had an almost two-fold higher prevalence of non-dipping pattern (80.8% (95% CI 52.8, 94.1) vs. 50.4% (95% CI 26.1, 74.5);p=0.008). Average sleep systolic BP dip in RVO patients was 6.1% vs. 11.9% in controls (p=0.004). More RVO patients had masked hypertension by ambulatory BPs than controls (71% vs. 50%), but this difference was not statistically significant. Conclusion Our data suggest an association between RVO and non-dipper BP pattern. Ambulatory BP monitoring may be useful in the evaluation of patients with RVO by identifying those who may benefit from more aggressive BP control.

Purpose: To evaluate the effect of a single intravitreal bevacizumab injection on visual acuity, contrast sensitivity and optical coherence tomographymea su red cen tral macular thickness in eyes with macular edema from branch re tinal vein occlusion. Methods: Seventeen eyes of 17 patients with macular edema from unilateral branch retinal vein occlusion were treated with a single bevacizumab injection. Patients were submitted to a complete evaluation including best corrected visual acuity, contrast sensitivity and optical coherence tomography measurements before treatment and one and three months after injection. Visual acuity, contrast sensitivity and optical coherence tomography measurements were compared to baseline values. Results: Mean visual acuity measurement improved from 0.77 logMAR at baseli ne to 0.613 logMAR one month after injection (P=0.0001) but worsened to 0.75 logMAR after three months. Contrast sensitivity test demonstrated significant improvement at spatial frequencies of 3, 6, 12 and 18 cycles/degree one month after injection and at the spatial frequency of 12 cycles/degree three months after treatment. Mean ± standard deviation baseline central macular thickness (552 ± 150 µm) reduced sig ni ficantly one month (322 ± 127 µm, P=0.0001) and three mo nths (439 ± 179 µm, P=0.01) after treatment. Conclusions: Bevacizumab injection improves visual acuity and contrast sensitiv i t y and reduces central macular thickness one month after treatment. Visual acuity returns to baseline levels at the 3month followup, but some beneficial effect of the treatment is still present at that time, as evidenced by optical coherence tomographymea sured central macular thickness and contrast sensitivity measurements.
