目的 了解不缝线巩膜隧道切口周边虹膜切除术的优缺点。方法 81例 (85眼 )原发性闭角型青光眼 ,以不缝线巩膜隧道切口行周边虹膜切除术。术后 1d、1mo观察术眼切口及眼前节、视力恢复情况和有无并发症。结果 术后 1d,全部术眼巩膜切口对合良好 ,无渗漏现象。虹膜周边孔清晰可见 ,全层切通 ,瞳孔圆形位正 ,视力保持在术前水平 ,无散光发生。仅 3眼 (3.5 % )术中出现少许前房出血 ,于术后 2 d吸收外 ,无其他术中、术后并发症。结论 采用不缝线巩膜隧道切口行周边虹膜切除术 ,具有手术安全性好 ,术后无线头刺激、不引起散光等优点。
Objective To understand the advantages and disadvantages of iridectomy without suture scleral tunnel incision. Methods Eighty-one eyes (81 eyes) with primary angle-closure glaucoma underwent circumferential iridectomy without suture scleral tunnel incision. Postoperative 1d, 1mo observed ocular incision and anterior segment, visual acuity and with or without complications. Results 1d after operation, all eyes scleral incision well, no leakage. Peripheral iris visible, full-thickness incision, pupil circular positive, visual acuity maintained at the preoperative level, no astigmatism. Only 3 eyes (3.5%) had a little intraoperative anterior chamber hemorrhage during 2 days postoperatively without any other intraoperative and postoperative complications. Conclusion The use of non-suture scleral tunnel incision peripheral iridectomy, with good surgical safety, postoperative wireless head stimulation, does not cause astigmatism and other advantages.
