9. Neovascular Glaucoma

A form of secondary open-angle glaucoma, this type is caused when an unusual new formation of blood vessels occurs on the iris and takes over the drainage canals.

Research has shown it is typically affiliated with another condition and does not stand alone. Treatment is minimal because it is difficult to manage.
