Overview

闭角型青光眼是一种眼疾,其中虹膜突出并阻塞虹膜角,导致房水积聚和眼内压增高。由于症状突然发作,需要立即就医。闭角型青光眼的治疗包括短期和长期方法。短期治疗包括使用像毛果芸香碱这样的眼药水,通过增加房水排出来降低眼内压力。然而,毛果芸香碱可能会引起视力模糊和夜盲等副作用。长期治疗选项包括激光虹膜切孔术,它在虹膜上打一个孔以引流房水,以及小梁切除术。这种手术会切除虹膜的一部分,并创建了一条新的引流路径。小梁切除术也称为滤过手术,因为排出的房水聚集在滤过泡中。

Transcript

在闭角型青光眼中,凸出的虹膜导致虹膜角膜角闭合,有效地阻塞了 Schlemm 管。

梗阻阻止房水流出,导致眼压突然升高。这会引发急性症状,如恶心、眼睛充血、呕吐和剧烈头痛。

闭角型青光眼的治疗包括短期药物治疗和长期手术途径。

短期紧急治疗旨在降低手术前的急性眼压。

例如,毛果芸香碱是一种胆碱模拟药物,通过打开小梁网有效增加房水引流。

但是,长时间使用可能会导致视力模糊和夜盲症等副作用。

闭角型青光眼的长期治疗包括激光和外科手术。

在激光虹膜切开术中,激光束用于在虹膜上打孔。这恢复了房水通过小梁网流出的常规路径。

在小梁切除术中,通过手术创建一条替代路径,以允许房水流出,绕过阻塞的虹膜角膜角。
