Persistent Hyperplastic Tunica Vasculosa Lentis (PHTVL) is best described as:

• A. Persistent Hyperplastic Tunica Vasculosa Lentis (PHTVL)
• B. Persistent Pupillary Membranes
• C. PHPV
• D. Persistent Hyaloid Artery

Answer: (A)

Persistent hyperplastic tunica vasculosa lentis refers to the vascular network that normally surrounds the developing lens failing to regress and remaining on the posterior surface of the lens. This creates a vascularized tissue or membrane behind the lens (retrolental membrane) and can be associated with lens opacities. It is distinct from persistent pupillary membranes, which cross the pupil, and from residual hyaloid/primary vitreous vessels that involve the vitreous and can extend to other posterior structures. So the description centers on tissue around the lens—the tunica vasculosa lentis—that persists and becomes hyperplastic.
