Glaucoma is a group of diseases that can damage the optic nerve in the eye and result in blindness. One type of glaucoma, called open-angle glaucoma, is often associated with increased pressure inside your eye. This type of glaucoma can lead to vision loss or even blindness. This fact sheet focuses on open-angle glaucoma, the most common form of the disease.

At the front of the eye, there is a small space called the anterior chamber. The anterior chamber lies between the lens and the cornea. Clear fluid flows in and out of the chamber to bathe and nourish nearby tissues and to keep the eye properly formed. In glaucoma, for unknown reasons, the fluid can drain too slowly out of the eye. As the fluid builds up, the pressure inside the eye rises. Unless this pressure is controlled, it may cause damage to the optic nerve and other parts of the eye, leading to vision loss.
