彩色多普勒超声对视网膜脱离的诊断价值

目的 评价彩色多普勒超声(CDFI)对视网膜脱离的诊断价值.方法 回顾31例患者35只眼视网膜脱离的超声图特征性表现,与手术结果进行对照分析视网膜脱离的诊断百分率.结果 35只眼视网膜脱离的诊断符合率97.1%(34/35),其中33只眼在玻璃体的膜样带状回声上检测出与视网膜中央动脉相延续的彩色血流信号.结论 CDFI检测出脱离的膜样带状回声上与视网膜中央动脉相延续的血流信号对视网膜脱离有特异性的诊断价值.

Color Doppler ultrasound in the assessment of the retinal detachment

Objective The aim of the study was to determine the diagnostic value of color Doppler ultrasound in the assessment of the retinal detachment. Methods The changes of ultrasonograph of the retinal detachment were retrospectively observed in 35 cases of 31 opei-ation proven retinal detachment patients. Results Color Doppler ultrasound had an accuracy of 97.1% (34/35) for diagnosing retinal detachment. In 33 cases of retinal detachment, the results of color Doppler flow imaging(CDFI) showed the color blood-flow signal in the vitreous membrane echo,extending with central retinal artery and vein. Conclusion For the color blood-flow signal in the vitreous membrane echo by CDFI ,extending with central retinal artery and vein, has a specificity of diagnostic value for retinal detachment, and the color Doppler ultrasound has a high accuracy for diagnosing retinal detachment.
