【摘要】：卒中作为继缺血性心血管疾病、癌症之后的人类第三大死亡病因,是成人获得性身体残障的最主要原因。然而,由于对颅内血管检查的困难,到目前为止,我们甚至不能清楚的解释临床各卒中的发病机制,这与其高发病率及高致死率的后果十分不相配。而后来彩色多普勒超声、磁共振等影像学的的发展得以让颅内血管的“庐山真面目”开始显现在我们眼前,但是由于其价格较贵、专业性及应用局限性等原因仍限制了我们对于颅内血管病变的研究。眼底中央动脉发自眼动脉,在其第一分支后被称为小动脉,这些小动脉的分层与颅内小动脉非常相似,且研究已经表明了视网膜微血管与颅内血管在胚胎学、组织学及病理学上的同源性。故眼底血管作为全身唯一能够直接观察且具无创检查的血管为我们研究颅内血管病变带来了曙光。本文将全面阐述视网膜改变与缺血性卒中的相关性。
[Abstract]:Stroke, the third leading cause of death after ischemic cardiovascular disease, is the leading cause of adult acquired physical disability. However, it is difficult to examine intracranial blood vessels so far. We do not even have a clear explanation of the pathogenesis of clinical stroke, which is incompatible with the consequences of high morbidity and mortality. The development of imaging, such as MRI, has allowed the "true face" of intracranial blood vessels to begin to appear in front of us, but it is more expensive. The study of intracranial vascular lesions is still limited by professional and limited application. The central ophthalmic artery originates from the ophthalmic artery and is called the arteriole after its first branch. The stratification of these arterioles is very similar to that of intracranial arterioles, and studies have shown that retinal microvessels and intracranial vessels are in embryology. Histologically and pathologically homologous. Therefore, the ocular fundus blood vessel, as the only direct and noninvasive blood vessel in the whole body, brings us the dawn for the study of intracranial vascular lesions. This article will comprehensively explain the retinal changes and deficiencies. The correlation of blood stroke.
