摘要
Schlemm管是围绕在前房角一周的房水流出管道,由若干小腔隙相互吻合而成,内壁仅有一层内皮细胞与小梁网相隔,外壁发出25~35条集液管与巩膜内静脉丛、睫状前静脉相通。由于Schlemm管是房水流出的必经通道,其房水排出通畅可维持正常的眼内压。若Schlemm管出现狭窄、塌陷、闭合等结构或功能的异常,房水流出受阻,可致眼压升高、青光眼发生。Schlemm管手术是指一类经Schlemm管增加房水引流通畅性的手术方式总称。随着临床对青光眼机制认识的不断加深,Schlemm管手术在不断创新,从传统到微创、从外路到内路。
Schlemm’s canal is an important channel for outflow of aqueous humor and one of the important tissues for maintaining intraocular pressure.Schlemm’s canal can lead to abnormal intraocular pressure and even glaucoma due to physiological and pathological changes.Schlemm’s canal sugery refers to a type of operation that increases the patency of aqueous drainage through Schlemm’s canal.With the deepening understanding of the mechanism of glaucoma in clinic and the progress of technology,Schlemm’s canal sugery is constantly innovating and developing.
