Persistent hyperplastic primary vitreous

Persistent hyperplastic primary vitreous (PHPV), also known as persistent fetal vasculature, is a rare congenital developmental malformation of the eye, caused by the failure of regression of the primary vitreous. PHPV typically presents unilaterally without association with systemic findings, but sometimes PHPV may be associated with rare systemic syndromes. Most cases of PHPV are sporadic, but it can be inherited as an autosomal dominant or recessive trait.
