彩色多普勒在脉络膜脱离型视网膜脱离的临床应用

目的 评价B型超声及彩色多谱勒血流成像(CDH)对脉络膜脱离型视网膜脱离的诊断价值.方法 16例脉络膜脱离型视网膜脱离患者,分别行常规B超并叠加CDH诊断,结合临床治疗及手术反馈信息,证实超声诊断准确性.结果 经手术验证,B超结合CDFI诊断脉络膜脱离型视网膜脱离符合率96.85%,B超及CDFI影像具有特征性表现.结论 应用B超结合CDFI,显著提高了对脉络膜脱离犁视网膜脱离的诊断准确性,并较精细的显示内眼情况.

The clinical application of Color Doppler flow Imaging in retinal detachment accompanied by choroidal detachment

Obiective To evaluate the diagnostic value of retinal detachment accompanied bychoroidal detachment using B-mode uitrasonographic and color doppler flow imaging (CDFI).Methods 16cases with retinal detachment accompanied by choroidai detachment were investgated by B-scan and add onCDFI.To prove the accuracy of diagnosis,the results of B-scan and CDFI was compared by clinical and surgeryinformation.Results The accuracy rate of diagnosis in retinal detachment accompanied by choroidaldetachment using B-scan and CDFI is 96.85 % which proved by surgery.The image of B-scan and CDFI havesome characteristics.such as:Displayed smooth hemispherical thick bands,CDFI showed the frequencyspectrum, some case shows retinal detachment and vitreous detachment between posterior polar and convexside of choroidal detachment band.Conelusians B-scan add on CDFI iS a good method which improved thediagnostic accuracy Of retinal detachment accompanied by choroidal detachment,and shows some detailsbefore surgery.
