术前B超检查在外伤性白内障中的应用价值

The Application Value of B-Ultrasound Scan on Traumatic Cataract

目的：探讨术前 B超检查对外伤性白内障后囊损伤的判定及应用价值。方法：外伤性白内障 60只眼术前采用 B超检查以判定晶体后囊情况，显微镜下行外伤性白内障摘除，直接观察术中后囊情况并记录。结果： 36只眼术前 B超检查后囊完整，其中 33只眼术中证实后囊完整，符合率 91. 7％， 24只眼术前 B超检查后囊不完整，术中证实 23只眼后囊存在大小不等的破损，符合率 95. 8％。结论：外伤性白内障术前 B超检查为非侵入性无痛性检查，操作简便，准确率高，对术前晶体后囊状态可提供重要的参考，可作为术前了解外伤性白内障后囊破损情况的常规检查方法，对手术操作和选择术式有指导意义。

Objective:To evaluate the diagnostic value of B-Ultrasound Scan on Traumatic Cataract.Methods:60 eyes of traumatic cataract underwent preoperative B-ultrasonograph and intraoperative microscopic examination to evaluate the situation of posterior lens capsule.Results:95.8％ cases has been confirmed the evaluation of B-Ultrasound Scan after the operations.Conclusions:For traumatic cataract,B-Ultrasound Scan is a harmless and accurate diagnostic method.
