复合式小梁切除术治疗原发性慢性闭角性青光眼观察

目的:观察复合式小梁切除术治疗原发性慢性闭角性青光眼的临床效果.方法:将68例88眼原发性慢性闭角性青光眼病例随机分为2组,观察组36例47眼实行复合式小梁切除术,对照组32例41眼采用传统小梁切除术.比较2组术后前房深度、眼压、睫状环阻滞性青光眼发生率及滤过泡情况.结果:术后早期浅前房发生率观察组为8.51%,对照组34.15%,观察组明显低于对照组(P＜0.05).术后睫状环阻滞性青光眼发生率观察组为0眼,对照组3眼(7.31%),观察组明显低于对照组.术后1年观察组42眼(89.36%)、对照组28眼(68.29%)眼压控制在21 mmHg(1 mmHg=0.133 kPa)以下,2组比较有显著性差异(P＜0.05).术后1年发生功能性滤过泡观察组43眼(91.49%)、对照组29眼(70.72%),2组比较有显著性差异(P＜0.05).结论:复合式小梁切除术最大限度地减少了原发性慢性闭角性青光眼术后早期浅前房及睫状环阻滞性青光眼的发生率及术后滤过道疤痕化的发生,提高了原发性慢性闭角型青光眼的手术成功率.

The Observation of Clinical Effects of Composite Trabeculectomy in Treating Primary Chronic Angle-Closure Glaucoma

Objective:To observe the clinical effects of composite trabeculectomy in treating primary chronic angle-closure glaucoma(PCACG).Methods:By randomly selecting,41 eyes of 32 PCACG patients were performed traditional trabeculectomy(control group),47 eyes of 36 PCACG patients were treated with composite trabeculectomy(observe group).There were comparative analysis of chamber depth、intraocular、the incidence of ciliary ring block glaucoma and filtering bubles between the two groups after operation.Results:After operation,the incidence of early postoperative shallow anterior chamber in observing group and control group were 8.3% and 34.15% respectively(P<0.05);The incidence of postoperative ciliary ring block glaucoma in observing group and control group were 0 and 7.31% respectively after operation;One year later,42 eyes(89.36%)were controlled below 21 mmHg in observing group,compared with 28eyes(68.29%)in control group,there was a statistically significant difference(P<0.05).One year later,functional filtering bubles in observing group and control group were 43 eyes(91.49%) and 29 eyes(70.72%) respectively,there was a statistically significant difference(P<0.05).Conclusion:Composite trabeculectomy reduces the incidence of early postoperative shallow anterior chamber、ciliary ring block glaucoma and occurrence of the filter corridor scar after operation on PCACG patients,improve the success rate of operation on PCACG patients.
