Eyes with persistent fetal vasculature (PFV) may be mistaken for retinoblastoma and provide a diagnostic challenge.
This study aimed to evaluate the role of color Doppler imaging (CDI) in children with persistent fetal vasculature.
Eyes with a diagnosis of PFV were evaluated by CDI.
Twenty eyes of 17 children were included. All had a confirmed diagnosis of PFV based on one or more of the following: clinical findings on funduscopy, characteristic findings on imaging modalities (ophthalmic gray-scale US, CT and/or MRI), typical findings observed intraoperatively, and histopathological analysis (after enucleation in one case). Blood flow within the PFV was demonstrated in 19 eyes in this series.
CDI is a noninvasive diagnostic tool that may add useful information on the presence of blood flow within the PFV and may substantiate the diagnosis of PFV in cases of uncertainty.
持续性胎儿血管（PFV）的眼睛可能被误诊为视网膜母细胞瘤，这给诊断带来了挑战。
本研究旨在评估彩色多普勒成像（CDI）在持续性胎儿血管患儿中的作用。
对诊断为 PFV 的眼睛进行 CDI 评估。
本研究纳入了 17 名儿童的 20 只眼。所有患儿均基于以下一项或多项检查确诊为 PFV：眼底镜检查的临床发现、影像学检查（眼部灰阶超声、CT 和/或 MRI）的特征性发现、术中的典型发现，以及组织病理学分析（1 例眼球摘除后）。本研究中，PFV 内血流在 19 只眼中得到了证实。
CDI 是一种非侵入性的诊断工具，它可以提供关于 PFV 内血流存在的有用信息，并在存在疑虑的情况下支持 PFV 的诊断。
