Corneal Neovascularization

Corneal Neovascularization (NV) is an abnormal condition that occurs as a result of some form pathology. New blood vessels grow from the edge of the cornea (the limbus) into both superficial or deep areas of the cornea. This disrupts the normal transparent nature of the cornea. The growth of new, immature blood vessels may lead to lipid exudation, persistent inflammation, and scarring, thus threatening corneal transparency and good vision. In advanced stages, ingrown blood vessels reach the visual axis, and can become permanently threaten vision. In patients with a history of corneal transplants, it may contribute to graft rejection.
