Pentacam眼前节成像分析系统在晶状体半脱位中的应用研究

目的 评估Pentacam眼前节成像分析系统在晶状体半脱位诊断和疗效评估中的应用价值.方法 通过测量50名(100只眼)正常人眼前房的深度,获得角膜直径4mm范围内6个对称点相对应的前房深度差异范围.对7例(9只眼)晶状体半脱位患者的Scheimpflug图像及6个对称点前房深度值和正常值范围进行对比分析.结果 Scheimpflug图像能直观显示晶状体脱位的方向,定量显示脱位的范围,通过三维前房分析系统对术后6个对称点前房深度值和正常值范围进行对比分析,可判断患者手术后的视觉效果.结论 Pentacam眼前节成像分析系统为晶状体半脱位临床诊断提供有效的证据,对术后疗效的评估具有一定的指导意义.

The clinical study on semiluation with pentacam Pentacam assessment of lens dislocation

Objective To diagnose eenssepn eaxaifian and evaluate the curative effect using Pentacam-Scheimflug System.Methods This clinical study comprised 50 (100eyes) healthy volunteers whose anterior chamber depth (ACD) ,central and 6 symmetry points in 4ram area were evaluated. The ACD of 7(9 eyes) patients with lens semiluxa were measured before and after surgery.Results Seheimpflug image can intuitive show the orientation and measure the range of lens dislocation . Evaluating the curative effect by comparing the differences of ACD before and after surgery.Conclusions Pentacam-Scheimflug System may supply effective proof for diagnosing lens seamilanafioy and also be a good way to evaluate the curative effect.
