What is corneal neovascularization?

Corneal neovascularization is the growing of avoidable blood vessels into the normally clear cornea. 
These blood vessels are a response to lack of oxygen or significant inflammation of the cornea.

When such vascularization of the cornea is observed, it is important to attempt to diminish and hopefully stop this vascular growth.

What caused corneal neovascularization?
A common cause of neovascularization is over-wear or sleeping with contact lenses, even with the best of lenses. The best treatment is to avoid contact lens wear for a period of time. When left untreated, progressive corneal neovascularization may lead to vision loss.

What are the symptoms of corneal neovascularization?
There is no pain involved initially. In some patients, there may be a feeling of dry eyes.
That’s why contact lens wearers are recommended to check their eyes yearly.
