Neovascularization of the Cornea

New (neo) blood vessel growth (vascularization) on the cornea. One of the most common cause of corneal neovascularization is contact lens wear, especially those made with older hydrogel contact lens materials such as HEMA (2-hydroxyethyl methacrylate) for both daily and extended wear.

Such older hydrogel materials have a relatively low oxygen transmissibility so the cornea ends up being starved of oxygen hence the response of the ingress of blood capillaries into the clear cornea to satisfy that oxygen demand.

There has been multiple causes proved to be involved with corneal neovascularization, including herpes simplex and corneal ulcers
