白内障的彩超诊断

The Diagnosis of Ultrasonography for Cataract

目的 :应用彩色多普勒诊断仪对白内障患者眼球进行检查 ,旨在探讨彩超在白内障的应用价值。方法 :选取经临床确诊的本院住院或门诊白内障患者 6 3例 1 0 8只眼。仔细观察晶状体前后缘及内部回声 ,观察玻璃体、视网膜等的形态、结构和内部回声 ,测量晶状体大小、后缘长度 ,用彩色多普勒观察患者眼球内部及视网膜中央动脉的血流情况 ,并记录结果。结果 :年龄相关性白内障分为皮质性白内障、核性白内障、后囊下白内障 ,超声表现为晶状体增厚或正常 ,后囊膜增长 ,回声增强、增厚 ,依晶状体混浊部位不同呈分布不一的稍强回声。外伤性白内障 ,由于损伤的程度不同导致晶状体声像图表现各异。先天性白内障 ,患眼晶状体回声明显增高 ,呈光团型 ,前后囊膜回声增强 ,毛糙。结论 :彩超诊断白内障简便、迅速、无创、可反复进行 ,弥补了眼科裂隙灯和检眼镜的不足 ,能全面了解眼球内的情况 ,在眼科临床诊疗及手术方式的拟定有不可替代的作用。

Objective:To evaluate the application value in Diagnosis for cataract with Color Dopple Flow Imaging(CDFI).Method:63 cataracts cases (108 eyes) were selected.observed the echos in superficial and posterior edges of the lens,the stractural and internal echo of vitreous and retina,measured the lens size and posterior capsule length,obsered the interior color flow of eye-ball and relina central artery,and recoreed the results.Result:age correlated cataract was divided into cortex cataract?nuclearness cataract and posterior capsule cataract.The main ultrasonic features were diffuse thickening or normal in lens,grew longer in posterior capsule membrane and became enhanced and thicker,The echos were differently distributed and more enhamced by turid in different part of lens.wound cataract,the ultrasonic images of lens were various by the various level of damage.Congenital cataract,the echos were enhamced and unsmooth in supericial and posterior capsule membrane of the lens.Itshows mass.Conclusion:The diagnosis of ultrasonography for cataract is a simple?quick and unharmful technique,and can do repeatly,remedy ophthalmology slit-lamp and eye-exame mirror.It cannot be replaced in clinical diagnosis,in the treatment of opthamology and selecting method of operation.
