小梁切除术中可调节缝线应用疗效的观察

摘要

目的观察可调节缝线在青光眼小梁切除术中的疗效。方法39例(45只眼)闭角型青光眼患者随机分为研究组23例(23只眼)和对照组16例(22只眼)，研究组行可调节缝线小梁切除术，对照组行常规小梁切除术，观察并比较两组患者术后眼压、前房及滤过泡情况。结果术后两组眼压较术前均明显下降。术后6个月时研究组眼压显著低于对照组，组间比较差异有统计学意义(约0.05)。研究组术后浅前房发生率为8.7%，显著低于对照组，组间比较差异有统计学意义(约0.05)。研究组术后功能性滤过泡形成率为86.9%，显著高于对照组，组间比较差异有统计学意义(约0.05)。结论青光眼小梁切除术中应用可调节缝线可使术后前房迅速形成，减少浅前房发生率，还可促进功能性滤过泡形成，从而提高青光眼手术的成功率。%Objective To observe the ef ect of adjustablesutures in trabeculectomy.Methods 39 cases (45 eyes)of angle-closed glaucomawere randomly divided into 2 groups:23cases (23 eyes) in study group wereperformed conventional trabeculectomy combined with the application of adjustablesutures and 16 cases (22 eyes) in control group were performed conventional trabeculectomy.Fol ow-upvisits were done to observe the intraocular pressure,anterior chamber depth andfiltering bleb.Results The intraocularpressure of both groupsdecreased obviously after surgery,in the 6th month postoperation,the ocularpressure of the study group was significantly lower than the control group,the dif erence was statistical ysignificant ( <0.05).The occurrence rate of flat anteriorchamber in study group was 8.7% which was significantly lower than that in thecontrol group,the dif erencewas statistical y significant ( <0.05),the formation ratioof functional filtering bleb in study group was 86.9% which was significantlyhigher than that in control group,thedif erence was statistical y significant ( <0.05).Conclusion Trabeculectomy with adjustablesutures can be ef ective in controlling intraocular pressure,avoiding fromshal ow anterior chamber,promoting the formation of filtering bleb and improvingthe success rate of operation.
