What is Glaucoma?

Glaucoma results when the pressure (IOP) inside the eye is elevated. This high pressure pinches and kills part of the optic nerve. When the optic nerve fibers die, permenant vision loss results. Three things are needed to diagnose glaucoma: high IOP, optic nerve loss, and visual field loss.
