目的 分析彩色多普勒显像 (colordopplerinspection ,CDI)对小儿外伤性白内障术前的预测作用 ,为临床手术设计及预后判断提供依据。方法 将 2～ 1 2岁外伤性白内障儿童 (childrentrau maticcataract,CTC)分为钝性伤组 ,2 2例 2 2只眼 ;穿通伤组 ,2 8例 2 8只眼。将其术前CDI的诊断与术中确诊的符合率进行比较分析。结果 钝性伤组符合率为 82 1 4% ,穿通伤组符合率为 72 72 %。结论 两组CDI诊断存在一定的假阴性 ,且在穿通伤组更明显 (P <0 0 5 )。
Objective To analyze the predictive value of colordopplerinspection (CDI) on preoperative traumatic cataract in pediatric patients, and to provide evidence for the clinical design and prognosis. Methods Childhood traumatic cataract (CTC) aged from 2 to 12 years was divided into blunt trauma group, 22 cases with 22 eyes, penetrating injury group with 28 cases with 28 eyes. The preoperative CDI diagnosis and intraoperative diagnosis of compliance rates were compared. Results The coincidence rate of blunt injury group was 82 1 4%, and the coincidence rate of penetrating injury group was 72 72%. Conclusion The diagnosis of CDI in both groups has some false negatives, and it is more obvious in the penetrating injury group (P <0.05).
