本世纪七十年代初,由于村上(1971年)和松尾(1973年)先后开始采用近代先进方法,着手研究眼内血管系统,从而开创了一个探索视网膜脉络膜循环的新纪元。迄今,尽管有关视网膜循环的许多问题基本上尚未得到解决,但已启发人们努力从解剖、生理、生化、组织化学,电镜等领域进行更深入广泛的研究。本文着重对视网膜毛细血管的分布、超微结构和循环的若干方面作一简要综述。 In the early 1970s, Murakami (1971) and Matsuo (1973) began to adopt modern and advanced methods to study the intraocular vasculature, thus opening up a new era for exploring the retinal choroidal circulation. To date, although many of the problems associated with retinal circulation have largely remained unresolved, they have inspired people to work more intensively and broadly on the anatomy, physiology, biochemistry, histochemistry, and electron microscopy. This article focuses on a brief overview of retinal capillary distribution, ultrastructure and circulation aspects.
