关于新生血管的发生,半个世纪以来,诸家的研究从假说到实验,实验中又从异体到同体,从远隔到临近间的组织培养,积累了丰富的资料。按新生血管是病理组织由于营养代谢需要所诱起的本能的补偿机制(再生过程)。眼底各类血管床对其周围环境和刺激反应不尽相同。视网膜血管床对缺氧状态比较敏感,而脉络膜血管床由于解剖上与玻璃膜和色素上皮的关系密切,受复杂的生理功能的
About the occurrence of neovascularization, for half a century, various studies from hypotheses to experiments, experiments from allogene to the same body, from far to near the tissue culture, accumulated a wealth of information. Neovascularization is the instinctive compensation mechanism (regeneration process) induced by pathological tissue due to the need of nutrition and metabolism. Fundus of all types of vascular bed on the surrounding environment and stimulus response varies. Retinal vascular bed is more sensitive to hypoxia, and the choroidal vascular bed as anatomical and vitreous membrane and pigment epithelial closely related by complex physiological functions
