[Persistence and hyperplasia of the primary vitreous body].

Persistent hyperplastic primary vitreous is a disease whose spectrum has continued to widen throughout the years; in fact, it probably comprises a number of nosological entities considered as isolated symptoms until today. Our study has shown that the disease can be congenital and affect both eyes in the same individual. The possibility of an etiopathogenic connection with retrolental fibroplasia cannot be excluded.
