100多年前,人们就发现,人体的许多部位存在各种屏障, 如血脑屏障、胎盘屏障等。其中,人类的眼睛之所以能够保持 眼内外环境的稳定性,保证视弼膜感光功能的安全,很大程度 上依赖于一种眼球的特殊屏障--血眼屏障。 现在,人类已经初步揭开了这层屏障的神秘面纱,发现血 眼屏障是眼部各种屏障构成的特殊代谢结构,可以选择性滤过 血液中的有用物质,从而维持眼内环境的稳定。当屏障受到有 害因素侵袭时就会影响其功能,造成代谢紊乱,导致眼部病变 的发生。
More than 100 years ago, people discovered that there are various barriers in many parts of the body, such as the blood-brain barrier and the placental barrier. Among them, the human eye has been able to maintain the stability of the eye inside and outside the environment, to ensure the safety of visual function as the Bismuth film, largely depends on a special eye barrier - blood-eye barrier. Now, human beings have already unveiled the mystery of this barrier, and found that the blood-eye barrier is a special metabolic structure formed by various barriers in the eye and selectively filters useful substances in the blood so as to maintain the stability of the eye environment. When the barrier is affected by harmful factors will affect its function, resulting in metabolic disorders, leading to the occurrence of ocular lesions.
