"Glaucoma results from damage to the optic nerve. Usually the damage is from increased pressure in the eye. The damage to the eye is irreversible and glaucoma can lead to blindness. The most common form, open-angle glaucoma, generally appears in middle age and seems to have a genetic component. In this type of glaucoma, vision loss occurs very gradually. One eye is often worse than the other. Other types of glaucoma are closed-angle glaucoma (a medical emergency) and congenital glaucoma (present at birth). Secondary glaucoma is usually associated with another eye disease or disorder, such as a very mature cataract, uveitis, bleeding, eye tumor, or an eye injury.
