摘要
目的分析20MHz B超观察眼外伤晶状体改变中的应用价值.方法回顾性调查分析住院眼外伤患者晶状体外伤手术资料完整者15例(15眼),将术中所见晶状体情况与术前20MHz B超检查结果进行比较,分析20MHz B超的检查价值.结果经手术证实晶体状后囊完整者13例,2例手术中可见后囊破裂;经手术证实晶状体内异物2例,均与20MHz B超术前检查结果相符.手术后视力低于0.01者1眼,0.01～0.1者2眼,0.12～0.3者8眼,0.5或以上4眼,较术前明显提高.结论20MHz超声对于晶状体外伤诊断有较高的诊断意义,可以运用于外伤性白内障晶状体囊检查,对于晶状体内异物有比较明确的诊断,同时观察晶状体内异物位置和后囊情况有助于设计手术方式.
Objective To discuss the application of 20MHz Bultrasonography in observing the features of lens in ocular trauma. Methods 15 cases of traumatic eye were examined by 20 MHz B-ultrasonography before operation and evaluated the status of the lens in operation. Results B-uhrasonography showed： posterior lens capsular unbroken in 13 eyes, posterior lens capsular rapture in 2 eyes, intralenticular foreign body in 2 eyes, all of them coincided with the founding of surgery. Visual acuity of all eyes were increased after surgery.The visual acuity was less than 0.01 in 1 eye,0.01 -0.1 in 2 eyes,0.12-0.3 in8 eyes,and ~0.5 in4 eyes. Conclusion 20MHz B-uhrasonography has the diagnostic value in the disease of lens,which can be used in the examination of lens capsule in ocular trauma, and can diagnose the intralenticular foreign body and the feature of posterior lens capsule.
