Persistent Fetal Vasculature (PFV), previously known as persistent hyperplastic primary vitreous (PHPV), is a congenital eye anomaly. This condition arises due to the failure of the fetal hyaloid vascular system to regress properly. Normally, this vascular network is present during fetal development to supply nutrients to the developing lens but regresses before birth. When it persists, it can lead to various ocular complications.
