Popis: Purpose: Patients with retinal vein occlusions (RVOs) are at increased risk of cardiovascular disease. Arterial stiffness is an independent risk factor for cardiovascular events. Our aim is to evaluate the arterial stiffness in patients with acute branch retinal vein occlusion (BRVO) by using cardio-ankle vascular index (CAVI). Methods: This prospective study included 42 patients (18 male, mean age 57.5 ± 11.3) with acute BRVO and a matched control group (by age, sex, and presence of hypertension) with 70 (26 male, mean age 54.4 ± 9.4) patients. All patients and control subjects underwent complete ocular examination and CAVI measurement. BRVO was diagnosed based on clinical examination. Results: There were no significant differences between baseline clinical and demographic characteristics, echocardiographic measurements of left ventricular ejection fraction, systolic and diastolic blood pressure, and body mass index of the BRVO and control group. Both right and left CAVI values were found significantly higher in BRVO group (7.94 ± 1.53 vs 7.28 ± 1.25, P < 0.05 and 8.06 ± 1.41 vs 7.30 ± 1.26, P < 0.05, respectively). There were no significant difference in right and left ankle-brachial index values between the groups (1.05 ± 0.10 vs 1.06 ± 0.08, P = 0.46 and 1.04 ± 0.12 vs 1.05 ± 0.08, P = 0.46, respectively). Conclusion: Arterial stiffness is an important mediator of cardiovascular diseases. We found that CAVI which is a novel marker of the arterial stiffness is increased in patients with acute BRVO compared to controls.
