The eye constantly maintains constant pressure inside of itself. This pressure is measured as part of an eye exam.If the pressure in the eye is too high, some nerves in the eye will die, and this progressive nerve death is known as glaucoma.

Increased pressure damages blood vessels and optic nerve.

In glaucoma, the nerves that die first are the ones that see around the edge or “periphery” of the vision.

Glaucoma can happen as its own primary disease, or as a result of other diseases such as uveitis

Treatment of glaucoma centers on lowering the pressure in the eye. This can be achieved with eyedrops, and if necessary with surgery.
