视网膜静脉阻塞(RVO)分为中央静脉阻塞(CRVO)和分支静脉阻塞(BRVO),是一类造成严重视力损害的疾病。近年来,由于一些传统风险因素,如高血压、糖尿病、吸烟等,视网膜血管疾病引起了极大的关注。而这些风险因素都不足以解释脑卒中的发展。视网膜血管的独特之处在于可通过非侵入式间接眼底镜直接看到眼底血管。已有报道认为RVO是脑卒中的风险因素。但是,关于RVO与脑卒中的关系,研究结果不一。 Retinal vein occlusion (RVO) is divided into central venous occlusion (CRVO) and branch vein occlusion (BRVO), is a class of diseases that cause serious visual impairment. In recent years, due to some traditional risk factors such as hypertension, diabetes, smoking, retinal vascular disease has caused great concern. None of these risk factors explain the development of stroke. Retinal vessels are unique in that they can be seen directly through a non-invasive indirect ophthalmoscope. It has been reported that RVO is a risk factor for stroke. However, the relationship between RVO and stroke, the results of different studies.
