先天性青光眼是由于房角发育障碍所致。在滤帘的前面有被单层细胞薄膜所覆盖的中胚叶残留组织。它表面的单层细胞薄膜是由狄氏膜和角膜内皮层延续而来,为 Barkan 所发现,故名 Barkan 氏膜。这层膜无渗透性,阻止房水排出,是眼压升高的主要原因; Congenital glaucoma is due to dyskinesia. In the filter in front of the monolayer cell membrane covered by the mesoderm residual tissue. Its surface monolayer of cell membrane is from the Dystrophy membrane and corneal endothelium continued from Barkan found, hence the name Barkan’s membrane. This layer of membrane permeability, prevent aqueous humor discharge is the main reason for increased intraocular pressure;
