Patients with RVO have an increased risk for cardiovascular disease and share multiple common risk factors. In this study, we investigated the endothelial function and arterial stiffness of patients with RVO compared to healthy-control (CL) subjects. We enrolled 40 consecutive patients with RVO and 40 CL subjects. RVO was diagnosed by an ophthalmologist, endothelial function was evaluated by flow mediated dilation (FMD) in the brachial artery, and carotid-femoral pulse wave velocity (PWV) and augmentation index (AIx) of the radial artery were measured to evaluate arterial stiffness and reflected waves, respectively. No significant differences were detected between the studied groups in sex, age, presence of hypertension or dyslipidemia, body mass index, systolic and diastolic blood pressure levels, total cholesterol levels, and smoking habits ( p &gt; 0.05 for all). However, patients with RVO had impaired FMD ( p = 0.002) and increased PWV ( p = 0.004), even after adjustment for several confounders. Both FMD and PWV were also significantly and independently associated with the development of RVO. Furthermore, a signi\ufb01cant and positive correlation between PWV and systolic blood pressure existed only in the CL group. Therefore, we have shown that RVO is associated with significant endothelial dysfunction and increased arterial stiffness. Our results strengthen the vascular theory, according to which, systemic endothelial dysfunction and arteriosclerosis play a significant role in the pathogenesis of RVO.<\/jats:p>","DOI":"10.1177\/1358863x20913609","type":"journal-article","created":{"date-parts":[[2020,4,20]],"date-time":"2020-04-20T07:25:33Z","timestamp":1587367533000},"page":"302-308","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":31,"title":["Endothelial
