超声检测视网膜脱离与玻璃体增殖机化

Detached Retina and Vitreous Membrane Detected with Color Flow Doppler Imaging

目的 探讨彩色多普勒血流显像 (CDFI)技术对视网膜脱离与玻璃体增殖机化的诊断价值。方法 用 CDFI及二维超声对 80例 96眼各种类型视网膜脱离 (RD)和玻璃体增殖机化引起异常膜状回声进行二维结构及系统检测血流信号。结果 RD和玻璃体增殖机化各有其特征性二维超声图像 ,脱离的网膜上可检测到血流信号。结论 CDFI对 RD及玻璃体增殖机化患者的诊断、手术方式选择及预后估计有重要价值。

Objective To evaluate the diagnostic value of C olor Flow Doppler Imagi ng (CDFI)on retinal detachment (RD) and vitreous menbranes.Methods 96 eyes in 8 0 cases with RD and vitreous membranes were measured by using 2-dimensional ult r asound and CDFI for image and blood flow iamging.Results RD had a characteristi c appearance clearly different from vitreous membranes.Areas of RD had detectabl e blood flow.Conclusion CDFI is worth to determine differentiat ion of RD and vitreous membranes.CDFI is useful to choose surgical method and to predict the progression of RD and vitreous membranes.
