摘要
目的评价UBM在晶状体微小脱位诊断中的应用。方法眼球钝挫伤后临床可疑晶状体脱位患者73例，分别由两位技师行UBM直接检查法和UBM间接检查法，探测晶状体悬韧带断裂位点的点钟位，计算检查所需时间。结果73例临床可疑晶状体脱位患者配合完成UBM直接检查法49例，完成率为67．12％；所有患者均可配合完成UBM间接检查法，完成率为100％；完成率差异具有统计学意义（P〈0．01）。49例可配合完成UBM直接检查法患者中确诊晶状体脱位37例，UBM间接检查法提示晶状体脱位38例，UBM间接检查法灵敏度97．29％，特异度90．91％，假阳性率16．67％，假阴性率2．70％，正确指数88．21％，阳性预测值94．74％，阴性预测值90．91％。49例可配合完成UBM直接检查法检查所需时间为（30．9±8．7）min；UBM间接检查法检查所需时间为（9．2±1．1）min，组间差异具有统计学意义（t=20．034，P〈0．01）。UBM直接检查法与UBM间接检查法检查晶状体脱位点钟位相近，差异无统计学意义（t=0．495；P=0．624）。结论联合应用UBM直接检查法和间接检查法可快速确诊晶状体微小脱位。
Objective To evaluate the application of ultrasound biomicroscopy （UBM） in the diagnose of slight lens dislocation. Methods Seventy-three patients with ocular contusion and clinical suspicion of lens dislocation were performed UBM direct examination and UBM indirect examination by two technicians for detecting the rupture o＇clock position of suspensory ligament of lens. The time required for examination was calculated. Results Among 73 cases with clinical suspicion of lens dislocation, 49 cases could cooperate with UBM direct examination. The completion rate was 67.35%. All cases could cooperate with UBM indirect examination. The completion rate was 100%. The difference was statistical significance （P 〈0.01）. Thirty-seven cases were final diagnosis of lens dislocation by UBM direct examination. Thirty-eight cases were prompted diagnosis of lens dislocation by UBM indirect examination. UBM indirect examination sensitivity was 97.29%, specificity 90.91%, false positive rate 16.67%, false negative rate 2.70%, the correct index 88.21%, positive predictive value 94.74%, negative predictive value 90.91%. The time required for UBM direct examination was 30.9min＋ 8.7min. The time required for UBM indirect examination was 9.2min＋ 1.1min. The differ- ence was statistical significance （t =20.034, P 〈0.01）. The rupture o＇clock positions of suspensory ligament of lens detected by UBM direct examination were close to the position detected by UBM indi- rect examination. The difference was no statistical significance （t =0.495, P =0.624）. Conclusions UBM direct and UBM indirect Combined examination is a fast, effective way for the final diagnosis of slight lens dislocation.
