玻璃体荧光光度测定(Vitreous fluorophotometry)是目前临床上发现血-视网膜屏障完整性为最早期改变的方法。血-视网膜屏障(从血-脑屏障-词派生而来)是由两组解剖结构组成的;(1)视网膜血管的内皮细胞和内皮细胞之间的紧密连接(tight junctipn);(2)视网膜色素上皮细胞彼此之间的紧密连接。在正常情况下,较大的非脂溶性分子,例 Vitreous fluorophotometry is the most clinically found blood-retinal barrier integrity of the earliest changes in the method. The blood-retinal barrier (derived from the blood-brain barrier- word) is composed of two groups of anatomical structures; (1) tight junctipn between endothelial cells and endothelial cells of the retinal blood vessels; (2) the retina Pigment epithelial cells in close contact with each other. Under normal circumstances, larger non-fat soluble molecules, for example
