目的讨论小梁切除术、巩膜咬切术和虹膜嵌顿术后浅前房的原因和发生情况。方法回顾性总结１９８６～１９９６年在我院眼科进行３种抗青光眼手术的３９０只各种青光眼病例。结果（１）术前眼压≤２１ｍｍＨｇ（１ｍｍＨｇ＝０．１３３ｋＰａ）者１０９只眼，小梁切除术６４只眼，术后浅前房９只眼，占１４．１％，巩膜咬切术３１只眼，术后浅前房７只眼，占２０．６％，虹膜嵌顿术１１只眼，术后无浅前房发生；（２）术前眼压２２～３５ｍｍＨｇ者１７５只眼，小梁切除术１０３只眼，术后浅前房２６只眼，占２５．２％，巩膜咬切术４６只眼，术后浅前房１５只眼，占３２．６％，虹膜嵌顿术２６只眼，术后浅前房５只眼，占１９．２％；（３）术前眼压＞３５ｍｍＨｇ者１０６只眼，小梁切除术４２只眼，术后浅前房１３只眼，占３１％，巩膜咬切术２３只眼，术后浅前房５只眼，占２１．７％，虹膜嵌顿术４１只眼，术后浅前房５只眼，占１２．２％．结论３种抗青光眼手术中，虹膜嵌顿术后浅前房发生率低；术前眼压控制正常后，术后浅前房发生率低。
Objective To discuss the causes and occurrence of shallow anterior chamber after trabeculectomy, sclera bite resection and iris incarceration. Methods A total of 390 cases of glaucoma were retrospectively reviewed in our department from 1986 to 1996. Results (1) 109 eyes with preoperative IOP ≤21mmHg (1mmHg = 0.133kPa), 64 eyes with trabeculectomy, 9 eyes with shallow anterior chamber after operation (14.1%), sclerectomy 31 Only 7 eyes of shallow anterior chamber, 20.6%, 11 eyes of iris incarceration, no postoperative shallow anterior chamber occur; (2) Preoperative intraocular pressure of 22 ~ 35mmHg 175 eyes, small 103 eyes underwent beam resection, 26 eyes underwent shallow anterior chamber, accounting for 25.2%, scleral buckling 46 eyes, postoperative shallow anterior chamber 15 eyes, accounting for 32.6%, iris incarceration 26 Only 5 eyes (19.2%) had shallow anterior chamber postoperatively, (3) 106 eyes had preoperative intraocular pressure> 35mmHg, 42 eyes had trabeculectomy, 13 eyes had shallow anterior chamber, accounting for 31%, scleral incision 23 eyes, postoperative shallow anterior chamber 5 eyes, accounting for 21.7%, iris incarceration 41 eyes, postoperative shallow anterior chamber 5 eyes, accounting for 12.2%. Conclusions In the three kinds of anti-glaucoma surgery, the incidence of shallow anterior chamber after iris incarceration is low. After the control of intraocular pressure is normal, the incidence of postoperative shallow anterior chamber is low.
