老年性白内障的B超诊断分析

目的分析老年性白内障患者B超声像图的特征性改变。方法对106例老年性白内障患者的B超声像图资料进行回顾性分析。结果106例（212眼）患者中，皮质型白内障145眼（68．4％），B超声像图表现为晶状体前后皮质区呈带状或环晕状强回声，核心区域呈梭型低回声；核型白内障48眼（22．6％），表现为晶状体核心区域呈强回声，自中心向皮质逐渐减弱；混合型白内障19眼（9．O％），表现为整个晶状体呈弥漫点团状强回声。结论B超检测对老年性白内障具有简单易行、无创、诊断符合率高、图像直观等特点，便于疾病的普查以及手术前后的对比观察，值得临床重视及推广应用。

The analysis of senile cataract diagnosis using B-scan

Objective To analyze characteristic ultrasonographic changes in senile cataract. Methods Ultrasonographic images of 106 senile cataract cases were analyzed by Retrospective analysis. Results The category of senile cataract in 106 cases, cortical cataract 145 eyes (68.4%)and the appearance in ultrasound was ring-halo like or girdle-shaped hyperechoic in lens cortex and spindle-shaped hypoechoic in lens nucleus.Nuclear type cataract 48 eyes(22.6%), B-scan showed hyperechoic in lens nucleus and echo waning from lens nucleus to cortex. Mixed type cataract 19 eyes(9.0%), B-scan showed diffused dotted or clot-like hyperechoic in entire lens. Conclusion B-scan is simple, noninvasive, high diagnostic, and has clear visual images. It is convenient to screen cataract and compare preoperation and post-operation, so it is worthy of attention and application in clinic.
