视网膜脉络膜的血流调控特点

Circulation control characteristics of retina and choroid

视网膜脉络膜的血流调节(包括自身调节、神经调节、体液调节以及神经血管调节等)机制不同,与视网膜脉络膜缺血性疾病的发生机制密切相关。视网膜脉络膜的血流特点也不同,临床上常会认为视网膜的血液供应主要来自视网膜动脉系统,事实上脉络膜才是视网膜血液供应的主要来源。本文阐述视网膜脉络膜的血流调控及血液循环特点,为深入探讨视网膜脉络膜血管性疾病的发病机制奠定基础。

The circulation mechanisms of retina and choroid are different in various aspects including autoregulation,neuro-regulation,humor regulation and neurovascular regulation,which is closely associated with the development of retinochoroidal ischemic diseases.The circulation characteristics of retina and choroid also have many imparities.It is usually considered that central retina artery predominantly contributes the blood supply of retina but in fact choroid does.This article details above topics so as to be able to explore the pathogeneses of retinochoroid vasculopathies in depth.
