Persistent Vetal Vasculature-Vitreoretinal Surgery

Persistent fetal vasculature (PFV), previously known as persistent hyperplastic primary vitreous (PHPV), is a spectrum of congenital anomalies caused by complete or partial failure of the fetal hyaloid vasculature to regress. The severity of the disease may vary depending on the affected intraocular structures and anatomical variations. The outcomes of surgery depend on the type, location, extent, and severity of the disease. The aim of this review is to focus on surgical indications and techniques, and the prognosis of PFV in the current literature and our clinical experience.
