To evaluate contrast-enhanced ultrasonography (CEU) and colour Doppler imaging (CDI) for detection of persistent vascularisation in retinal detachment.
In 22 eyes, retinal detachment (n=13) and vitreous membranes (n=9) were confirmed by ophthalmological examination, during cataract surgery, by histopathology or after vitreoretinal surgery. Tentative diagnosis of retinal detachment or vitreous membrane was made using grey-scale B-mode ultrasonography. Assessment of retinal detachment was based on the presence or absence of vascularisation in the membranous structure using CDI and CEU.
Sensitivity, specificity, positive-predictive value and negative-predictive value of grey-scale ultrasonography in differentiating retinal detachment from vitreous membrane were 92·3%, 66·6%, 80% and 85·7%. In 91% of eyes, colour Doppler assessment was unsuccessful due to the movement of the eye. Persistent vascularisation was demonstrated in all cases of retinal detachments with CEU. CEU was 100% accurate for detection and differentiation between retinal detachment and vitreous membrane.
CEU is a useful clinical tool for the diagnosis of retinal detachment and vitreous membrane in dogs and cats.
评估超声造影(CEU)和彩色多普勒成像(CDI)在检测视网膜脱离中持续性血管化方面的作用。
22只眼睛中,视网膜脱离(n = 13)和玻璃体膜(n = 9)通过眼科检查、白内障手术期间、组织病理学检查或玻璃体视网膜手术后得以确诊。视网膜脱离或玻璃体膜的初步诊断采用灰阶B型超声检查。使用CDI和CEU根据膜状结构中血管化的有无对视网膜脱离进行评估。
灰阶超声在区分视网膜脱离与玻璃体膜方面的敏感性、特异性、阳性预测值和阴性预测值分别为92.3%、66.6%、80%和85.7%。在91%的眼睛中,由于眼球运动,彩色多普勒评估未成功。所有视网膜脱离病例经CEU检查均显示有持续性血管化。CEU在检测和区分视网膜脱离与玻璃体膜方面的准确率为100%。
CEU是诊断犬猫视网膜脱离和玻璃体膜的一种有用的临床工具。
