观察小梁切除术联合玻璃体抽液术治疗术中有恶性青光眼倾向患者的疗效。 方法：青光眼患者19例 20眼术中从角膜穿刺口注水恢复前房检查巩膜瓣渗漏情况时，表现为前房浅眼压高的患者，予以玻璃体穿刺抽液、前房注黏弹剂的方法治疗。 结果：患者19例术后无1例浅前房，出院眼压为5~22.5（平均10.4）mmHg，视力较术前提高者5例6眼，下降者9例9眼，3例3眼有玻璃体出血。 结论：小梁切除术中出现恶性青光眼倾向患者常为伴有睫状体前位晶状体前移的闭角型青光眼，术中联合玻璃体抽液术，可有效预防术后恶性青光眼的发生。

To investigate the effect of trabeculectomy combined with vitreous aspiration in treating malignant glaucoma. METHODS:Nineteen patients (20 eyes) with shallowing of the anterior chamber and high intraocular pressure following trabeculectomy were treated with viscoelastics injected to the anterior chamber combined with vitreous aspiration. RESULTS:The intraocular pressure of 19 patients ranged from 5 to 22.5 mmHg, the average was 10.4 mmHg .The visual acuity of 5 patients (6 eyes) increased, and the visual acuity of 9 patients(9 eyes) declined. Vitreous hemorrhage occurred in 3 patients (3 eyes). CONCLUSION:The pathogenesis of malignant glaucoma includes forward displacement of the ciliary body and lens. Trabeculectomy combined with vitreous aspiration can prevent malignant glaucoma effectively.
