120例老年性白内障患者眼生物结构测量参数分析

Analysis of Ocular Biological Structure Parameter of 120 Patients with Senile Cataract

目的：了解大理地区老年性白内障患者眼生物结构参数的正常值范围。方法：使用德国蔡司公司眼科专用 A／ B超超声诊断系统对 120例 (162只眼 )老年性白内障的眼生物结构参数进行测量。结果：老年性白内障其眼轴长度不随年龄增长而增大，晶体厚度随年龄增长而增厚，前房深度随年龄增加而逐渐变浅，玻璃体长度不随年龄增长而增大。结论：白内障患者眼生物结构参数测量结果，对临床有指导意义，亦可作为大理地区白内障患者眼生物结构参数的正常参考值。

Objective:To investigate the normal range of ocular biological structure parameter of patients with senile cataract in Dali. Methods: The ocular biological structure parameter of 120 cases (162 eyes) of senile cataract were measured by A／ B ultrasonic diagnostic system made in Deiss Company in Germany specially for eyes. Results: With the increase of age, the length of optic axis was unchanged, and the thickness of lens was increased, and the depth of anterior chambers became shallower, and the length of vitreous was stable. Conclusions: The ultrasonic parameters of ocular biological structure of patients with senile cataract are significantly important for clinical guide.In addition,they are also as the normal range of ocular biological structure parameters of patients with senile cataract in Dali.
