永存胚胎血管(persistent fetal vasculature，PFV)，也称永存原始玻璃体增生症( persistent hyperplastic primary vitreous，PHPV)，是一种先天性眼病，多发现于婴幼儿时期。因大多数患儿单眼发病、症状隐匿，且易被误诊为单纯的先天性白内障，常常延误手术治疗的最佳时机。因此，正确的诊断和适宜治疗方式的选择对于患儿视功能的预后尤为重要。本文报道了1例6岁6个月的男性患儿，诊断为混合型PFV，眼部特征表现为先天性白内障和黄斑区结构错位。

Persistent fetal vasculature (PFV), also known as persistent hyperplastic primary vitreous (PHPV), is a congenital ocular anomaly, which is common in infants and young children. Due to most children have unilateral occurrence, insidious symptoms and are easily misdiagnosed as simple congenital cataract, the optimum time for treatment is often delayed. Therefore, correct diagnosis and appropriate treatment are particularly significant for the prognosis of PFV children’s visual function. A male child aged 6 years and 6 months with a diagnosis of combined PFV is reported, whose ocular features were congenital cataract and structural dislocation of macula.
