超声对玻璃体内膜样病变的鉴别诊断

Ultrasonography diagnosis of vitreous light membrane

目的 探讨高频超声对玻璃体内膜样病变的诊断价值。方法 应用高频超声对 6 4只眼球进行多切面扫查 ,清晰显示眼球内容物、视神经和视网膜中央动脉并进行脉冲多普勒取样。结果 6 4只眼球中有 6 1只眼球超声诊断与手术结果符合 ,正确率为 94 .5 %。结论 高频超声检查能够使 95 %左右的患者玻璃体内膜状物的性质得以明确 。

Objective To investigate the echographic features and to discuss the value in the diagnosis of vitreous light membrane.Methods Sixty four eyes with vitreous light membrane were performed preoperatively examinations by HI frequency B mode ultrasonography. Results We found the post operative results of 59/64 eyes accorded with the preoperative diagnosis. The coincidence rate of diagnosis was 95%.Conclution HI frequency B mode ultrasonography has special value to diagnose and distinguish vitreous light membrane.
