二次可调整缝线在小梁切除术中的临床观察

Clinical observation on the quadratic adjustment suture in glaucoma trabeculectomy

目的:观察二次可调整缝线在小梁切除术中的疗效及安全性。方法:将173例(343眼)分为对照组和治疗组,观察两组术后眼压、前房及并发症的情况,并作统计学分析。结果:治疗组术后低眼压发生率12.4%,对照组术后低眼压发生率为25.5%,经统计学分析差异有显著性(P<0.01)。治疗组术后浅前房发生率2.2%,对照组术后浅前房发生率为8.5%,经统计学分析差异有显著性(P<0.05)。治疗组术后前房出血,脉络膜脱离,低眼压性黄斑病变发生率9.6%,对照组术后前房出血,脉络膜脱离,低眼压性黄斑病变发生率36.4%,差异有显著性(P<0.005),出院时两组间功能性滤过泡差异无显著性(P>0.01)。结论:二次可调整缝线在小梁切除术中可使术后前房迅速形成,减少术后早期并发症,疗效确切并可增加手术安全性。

AIM： To observe the efficiency and safety of quadratic adjustment suture in glaucoma trabeculectomy. HETHODS： One hundred and senventy-three cases （343 eyes） with primary glaucoma were divided into two groups randomly and the quadratic adjustment suture for sclera-flap combining with trabeculectomy was applied to treatment group of 88 cases （178 eyes）. The intraocular pressure （IOP）, anterior chamber depth, filtering action and complication of post-operation were observed. RESULTS： The low intraocular pressure for the treatment group was 12.4%. The contrasting group was 25.5%（P〈0.01）. The shallow anterior chamber for the treatment group was 2.2% and the contrasting group was 8.5%（P〈0.05）. The complication of hyphema, choroidal detachment, hypotony maculopathy for the treatment group was 9.6%. The contrasting group was 36.4%（P〈0.005）.The functional follicle type Ⅰ＋Ⅱ for the treatment group was 98.4%. The contrasting group was 96.4% （P〉0.01）. CONCLUSION： Applying the adjustment sutune for sclera-flap conbine with trabeculoctomy can prevent post-operation shallow anterior chamber and reduce the incidences of the complication of low intraocular pressure, etc.
