B超对外伤性白内障后囊损伤的判定

目的 应用Ｂ超术前检查外伤性白内障后囊的状态并与手术所见晶体后囊损伤进行临床对比。方法 穿通伤所致外伤性白内障４４只眼,术前Ｂ超判定晶体后囊是否完整。显微镜下行外伤性白内障摘除,目测判断晶体后囊是否破损。结果 后囊完整组２１只眼,术中证实后囊完整者１９只眼,符合率为９０．５％;后囊不完整者２３只眼,术中证实后囊均存有破损,符合率为１００．０％。结论 Ｂ超对术前晶体后囊状态可提供重要的参考,对手术操

Determination of posterior lens capsule status in traumatic cataract with B-ultrasonography

Objective To determine the status of posterior lens capsule in traumatic cataract with B ultrasonography.Methods 44 eyes of traumatic cataract were studied. The integrity of posterior lens capsule was evaluated with B ultrasonography before surgery. Cataract extraction was performed under microscope and the status of posterior lens capsule was recorded.Results 21 eyes showed complete posterior lens capsule in B ultrasonography. Of them, 19 eyes (90.5%) were confirmed by surgery. Other 23 eyes with posterior lens rupture determined before operation were all confirmed by surgery (100.0%).Conclusion B ultrasonography is helpful in evaluating the integrity of posterior lens capsule and choosing the strategy of surgery.
