复杂玻璃体视网膜疾病的彩色多普勒超声诊断特征

目的探讨彩色多普勒血流成像(CDFI)技术对复杂玻璃体视网膜疾病的超声诊断特征。方法对518例(678只眼)复杂玻璃体视网膜疾病包括玻璃体积血、玻璃体后脱离、玻璃体劈裂、视网膜脱离、脉络膜脱离、糖尿病视网膜病变等,应用眼科专用B超和CDFI诊断仪对同一患者进行检查,分别按照B超和CDFI的诊断标准予以诊断,再经手术证实,最终判断B超及CDFI检查结果的准确性。结果 CDFI检测复杂玻璃体视网膜疾病的阳性眼数高于B超诊断仪。视网膜脱离、玻璃体后脱离组的B超与CDFI检测结果比较、脉络膜脱离和玻璃体机化膜组的B超与CDFI检测结果比较,差异均有统计学意义(均P＜0.05)。结论综合应用CDFI的形态观察和血流特征两种分析方法,可显著提高诊断复杂玻璃体视网膜疾病的准确性,为临床提供可靠的诊断依据。

Color Doppler flow imaging in the diagnosis of complex vitreoretinal diseases

Objective To investigate the advantages of Color Doppler flow imaging (CDFI) in the diagnosis of complex vitreoretinal diseases Methods Both CDFI and B mode ultrasonographic studies were performed on 518 cases (678 eyes) vitreoretinal diseases, such as vitreous hemorrhage, posterior vitreous detachment, vitreoschisis, retinal detachment; choroidal detachment and diabetic vitreoretinopathy The accuracy of diagnosis by B mode and CDFI on the same case was compared with results of surgery Results Comparing between CDFI and B mode ultrasonographic, CDFI has more advantage in the diagnosis of the complicated vitreous retina disease than other simple retina diseases ( P <0 05) Conclusions CDFI is good diagnostic method for complicated vitreoretinal diseases Using CDFI sensitivity and veracity were obvious improved than using B mode CDFI can get more information for clinical diagnosis
