Glaucoma is a group of conditions that damage the optic nerve, which is vital to good vision. The damage is often caused by an abnormally high pressure in your eye. This pressure can damage the millions of nerve fibers that carry visual information from your eye via the optic nerve to your brain. The optic disk is the point where the fibers from the retina meet before entering the optic nerve. As your optic nerve deteriorates, blind spots develop in your vision. Left untreated, glaucoma can lead to irreversible blindness.
