Persistent fetal vasculature - Clinical spectrum.

Persistent fetal vasculature (PFV) is a congenital anomaly caused due to incomplete regression of the hyaloidal fetal vasculature.[123] Fig. 1a shows a Mitterndorf dot – a circular opacity on the posterior lens capsule, nasal to the center, which represents the anterior attachment of the hyaloid artery. Fig. 1b shows limited anterior PFV obscuring the visual axis with a classical stalk. Fig. 1c demonstrates PFV presenting with a vascularized membrane and prominent ciliary processes. Fig. 1d images the remnant posterior end of the stalk, the Bergmeister papilla. Identification of these clinical signs enables correct diagnosis and management of PFV.
