目的对87例原发性青光眼实施巩膜内湖成形小梁切除术并进行疗效观察。方法在浅层巩膜瓣下将边长1mm的等腰三角形中层巩膜片切除,形成巩膜内湖,结膜瓣作连续缝合。术毕即出现浅前房,术后1d达术前水平。结果随访1～3年,对视力、眼压、滤过泡及手术并发症等情况进行观察,远期降压成功率98.1%,功能滤过泡形成91.6%,8.4%无明显滤过泡形成着仍能长期维持正常眼压。结论巩膜内湖成形小梁切除术疗效肯定,可能兼具内引流作用,是一种较理想的抗青光眼手术。 Objective To conduct 87 cases of primary glaucoma labyrinthine trabeculectomy and observe the curative effect. Methods Under the superficial scleral flap, an isosceles triangle middle sclera was excised to form a scleral labyrinth and conjunctival flap for continuous suture. Shallow anterior chamber appeared surgery, 1d postoperative preoperative level. Results The patients were followed up for 1 to 3 years. Visual acuity, intraocular pressure, filtration bleb and surgical complications were observed. The success rate of long-term blood pressure reduction was 98.1%, functional filtration bleb formation 91.6%, and 8.4% Still can maintain long-term normal pressure. Conclusions The scleral labyrinthine laminectomy is effective and may be both an internal drainage and an ideal anti-glaucoma surgery.
