青光眼小梁切除术后滤道阻滞的早期手术治疗

Early operation treatment of filter channel obstruction after trabeculectomy of glaucoma

目的：探讨小梁切除术后滤道阻滞的处理方法。方法回顾分析25眼术后1个月内发生滤道阻滞患者临床资料，根据小梁切除术后滤道阻滞不同部位，在术后1个月内切口粘连不紧密时，内部阻滞的患者通过缩瞳、角膜侧切口将前粘连的虹膜周切口分离，必要时扩大虹膜周切口，恢复周边前后房的交通；中部阻滞的患者重建小梁切口，确保其通畅；外部阻滞的患者术后1个月内结膜瓣、巩膜瓣剥离。结果眼压下降与术前眼压比较，差异显著。观察6-12个月，眼压稳定在13-21 mmHg。结论小梁切除术术后1个月内，切口粘连并不十分紧密，采取适当的措施是可以恢复滤过功能的。

Objective To probe into the treatment method of filter channel obstruction after trabeculectomy. Methods Filter channel obstruction occurred in 25 eyes within one month after trabeculectomy,and they were retrospectively analyzed. According to different parts of obstruction,they were divided into three types namely inner obstruction, middle obstruction and outer obstruction. Patients with inner ob-struction were given miosis, separation of the anterior synechia, and expansion of peripheral iris incision when necessary. Patienrts with mid-dle obstruction were given reconstruction of the trabecular incision. Patienrts with outer obstruction were given conjunctiva or sclera flap dis-section within 1 month afer trabeculectomy. Results Postoperative IOP （ intraocular pressure） decreased significantly compared with preop-erative IOP. The IOP stabilized at 13-21 mmHg in the fallowing 6-12 months after operation. Conclusion Taking appropriate measures could restore the filtration function within one month after trabeculectomy when the incision adhesion was not very close.
