年龄相关性黄斑变性(AMD)是引起老年人群不可逆性视力损害的常见眼病。视网膜色素上皮细胞(RPECs)间紧密连接(TJ)是血-视网膜外屏障(oBRB)的重要结构单元。紧密连接在AMD的发病过程中有所缺陷，进而促进oBRB的破坏，加速AMD的发生和进展。本文将对紧密连接与紧密连接蛋白在维持oBRB功能、紧密连接蛋白异常与oBRB破坏在AMD发病过程中的作用研究进行综述，以期为AMD治疗的研究提供新的思路。

[Abstract]
Age-related macular degeneration(AMD)is a common eye disease causing irreversible visual impairment in the elderly. The tight junction(TJ)between retinal pigment epithelium cells(RPECs)is an important structural unit of the outer blood retinal barrier(oBRB). The TJ is defective in the pathogenesis of AMD, which in turn promotes the destruction of oBRB and accelerates the occurrence and progression of AMD. In this paper, the roles of TJ and TJ protein in maintaining oBRB function, TJ protein abnormality and oBRB destruction in the pathogenesis of AMD were reviewed, aiming to provide new ideas for the treatment of AMD.
