眼前节分析系统对青光眼LT手术前后房角宽度检查分析

Analyses of the chamber width before and after LT by the anterior eye segment analystem

目的使用眼前节分析系统(AnteriorEyeSegmentAnalystem)对青光眼LT手术房角宽度进行测量,初步报告其手术前方法后前房角宽度的改变,并对该系统的临床应用价值进行评价。使用眼前节分析系统对10例(12只眼)LT手术患者,手术结前后的房角宽度进行测量,记录测量值利用SPSS10.0统计分析软件对房角宽度的改变值进行T检验,进行统计学分析。果青光眼LT手术前房角宽度平均分别为14.06度。手术后房角宽度23.38,手术前后的房角宽度差异有显著(t=-12.9.<005),有统计学意义.结论手术以后房角宽度变宽,肯定手术效果。通过眼前节分析系统EAS-1000可明显明显观察房角宽度的变化。眼前节分析系统能在自然状态下进行活体、定时、定量的检测。该系统检查结果客观,操作方法简便,可作为判断LT手术效果、筛选原发性闭角型青光眼的手段之一。

Objective To analysis the changes of anterior chamber width perioperatively in glaucoma operation （LT） by the anterior eye segment analystem （EAS-1000）, and to evaluate the value of clinical application of EAS-1000.Methods Twelve eyes of ten eases＇ antcsior chamber widths were measured perinpdr＇thvdly at the laser hole of iris. All data were analyzed by SPSS12.0 statistics software. Pvalue, which was less than 0.05, was eonsidered significant. Results The average preoperative width was 14.06 degree. The postoparation width was 23.38 degree. The deviation was significant （t=-12.9. P〈0.05）. Conclusion The anterior chamber width was broaden after glaucoma operation. Those changes could be. ohserved by EAS-1000. It could detect the anterior chamber width in raw state timely and quantitatively. This system can be used objectively and conveniently. It can be a method of screening close angle glancoma as same as evaluating the operation effect.
