Abstract:

Persistent fetal vasculature (PFV) is a spectrum of disorders resulted from abnormal regression of ocular fetal vessels, which is classified into three types of anterior, posterior as well as combined. PFV presents sporadic with 95% of which is unilateral. The clinical manifestations of PFV are diverse with so many perplexed complications and is easily confused with other common eye diseases in infants and young children, made clinical diagnosis more difficult. There are no authoritative guidelines to guide treatment of PFV, and controversies exist in the treatment attitude of posterior pole lesions and the selection of surgical incisions. Moreover, clinicians do not know enough about PFV, resulting in a high rate of missed diagnosis and misdiagnosis, and the overall prognosis is poor. Therefore, the relevant literature on its embryonic origin and etiology, clinical manifestations, diagnosis and differential diagnosis, treatment, prognosis and basic research progress were reviewed.

Key words: Persistent fetal vasculature, Persistent hyperplastic primary vitreous, Hyaloid vessels, Surgery treatment
