眼内组织的营养是由视网膜血管、葡萄膜血管和房水完成的。在形态学和生理学上，视网膜血管与大脑中的血管相似。毛细血管的内皮细胞通过紧密连接彼此连接，阻力血管对大量药物的反应很差，并且通过视网膜的血流是自动调节的，并且很少受到交感神经系统的影响。虹膜的血管也具有类似于大脑中的血管的形态和渗透性特征，但它们受到交感神经的强烈影响，并对许多药物起反应。血液流动是自动调节的。脉络膜和睫状突的血管与小肠和肾脏中的血管相似。毛细血管的内皮细胞是有孔的;血管对交感神经刺激和大量血管活性药物有反应。血液流动的自动调节在睫状体中是中等的，并且在脉络膜中非常差或不存在。
The nutrition of the intraocular tissues is accomplished by the retinal vessels, the uveal vessels, and by the aqueous humor. Both morphologically and physiologically the retinal vessels are similar to those in the brain. The endothelial cells of the capillaries are attached to each other by tight junctions, the resistance vessels respond poorly to a large number of drugs, and the blood flow through the retina is autoregulated and very little affected by the sympathetic nervous system. The blood vessels of the iris also have morphological and permeability characteristics similar to those in the brain but they are under a strong influence from the sympathetic nerves and react to many drugs. The blood flow is autoregulated. The blood vessels of the choroid and the ciliary processes are similar to those in the small intestine and in the kidney. The endothelial cells of the capillaries are fenestrated; the vessels respond to sympathetic nervous stimulation and to a large number of vasoactive drugs. Autoregulation of the blood flow is intermediate in the ciliary body and very poor or absent in the choroid...
