目的：研究青光眼的新术式──中层巩膜切除联合深层巩膜咬切术对青光眼的治疗效果。方法：新术式组３３例（４０眼）行中层１／３厚，三边边长均为３ｍｍ的三角形巩膜瓣切除联合深层巩膜咬切。对照组２６例（３０眼）行常规式滤过术。两组病例均观察近期（６个月以内）和远期（７个月以后）的控压效果。结果：近期疗效，新术式组眼压被控制３７眼，成功率 ９２． ５％；对照组眼压被控制２８眼，成功率 ９３．３％，两组近期疗效接近。远期疗效，新术式组眼压被控制３５眼，成功率８７．５％；对照组眼压被控制２０眼，成功率６６．７％。两组病例远期疗效相比有显著差异（Ｐ＜０．０１）。结论：新术式近远期疗效可靠，是一种理想的抗青光眼术式。
OBJECTIVE: To study a new type of glaucoma surgery - the treatment of glaucoma by sclerectomy combined with deep sclerectomy. Methods: Thirty - three cases (40 eyes) in the new surgical group were treated with triangular scleral flap resection and deep scleral bite resection with a middle third of the thickness and a trilateral side length of 3 mm. Control group, 26 cases (30 eyes) underwent routine filtration. Both groups were observed in the recent (6 months) and long-term (7 months later) control effect. Results: In the short term, intraocular pressure was controlled in 37 eyes in the new surgical group with a success rate of 92. 5%; control group intraocular pressure was controlled 28 eyes, the success rate of 93.3%, the two groups near effect. Long-term curative effect, the new type of intraocular pressure was controlled 35 eyes, the success rate was 87.5%; control group intraocular pressure was controlled 20 eyes, the success rate of 66.7%. There was significant difference between the two groups in long-term efficacy (P <0.01). Conclusion: The new surgical approach is reliable in the short and long term and is an ideal anti-glaucoma procedure.
