超声对三硝基甲苯白内障的诊断价值

摘要

Objective To evaluate the diagnostic value of ultrasonography on trinitrotoluene (TNT)cataract.Methods Power ultrasound diagnostic apparatus and slit-lamp were used to check and analyze the features of 30 TNT cataract cases(60 eyes).Results The sensitivity and specificity and confirmed rate were 90.00％ ,70.00％ and 87.14 ％.Conclusions The ultrasonography sensitivity of TNT cataract was similar to slit-lamp.It can provide reliable information for diagnosis and treatment of TNT cataract.%目的 探讨超声对三硝基甲苯(TNT)白内障的诊断价值.方法 应用超声诊断仪对疑为TNT白内障30例60只眼进行超声检查,并同时行裂隙灯显微镜检查,以裂隙灯显微镜检查结果为诊断标准,计算超声对TNT白内障诊断的敏感性、特异性、诊断符合率.结果 超声检出TNT白内障的敏感性90.00%、特异性为70.00%、诊断符合率为87.14%.结论 超声对TNT白内障晶状体病变诊断的敏感性与裂隙灯检查相近,对眼球内部结构了解优于裂隙灯检查.超声可作为诊断TNT白内障及其合并症的常规及术前检查的一种重要手段.
