恶性青光眼的手术疗效观察

Mechanism and treatment of malignant glaucoma

目的探讨引起青光眼的可能机制及恶性青光眼的治疗方案。方法分析２３例（３４只眼）恶性青光眼发病情况，并分别采取了药物治疗、晶体摘除、玻璃体切除、前房成形术或几种手术联合治疗的方法。结果药物治疗有效率为３５．３％，晶体摘除联合玻璃体切割、前房成形术全部获得成功。结论恶性青光眼发病机理可能与玻璃体前界面、睫状体和虹膜后面之间膜状物形成有关，对保守治疗失败者采用联合手术方法可取得良好效果。

Objective To investigate the possible mechanism and the treatment of malignant glaucoma.Methods The onsets of 34 eyes in 23 cases of malignant glaucoma were analyzed and the patients were treated with medicine, lens extraction, vitrectomy, anterior chamber plastic operation or combined procedures. Results The effective rate in medical treatment was 35.3%. Combined procedures (lens extraction associated with vitrectomy and anterior chamber plastic operation) were all successful. Conclusions The possible mechanism of malignant glaucoma may be concerned with the formation of membranoid substance among vitreous face, ciliary body and posterior iris. Those who failured to medical therapy and were treated with combined operations may have good effect.
