tunica vasculosa lentis

tunica vasculosa lentis
the vascular envelope that encloses and nourishes the developing lens of the fetus; it consists of the pupillary membrane in the region of the pupil, the capsulopupillary membrane around the edge of the lens, and the capsular membrane at the back of the lens. It normally degenerates during the late fetal period when the hyaloid artery degenerates.
