复杂玻璃体视网膜疾病的彩色多普勒超声诊断特征

Color Doppler flow imaging in the diagnosis of complex vitreoretinal diseases

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。

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
