Glaucoma FAQs

What Is Glaucoma?

Glaucoma is an eye disease in which the optic nerve is damaged, usually from elevated pressure within the eye. The optic nerve damage may cause peripheral or central visual loss. High pressure within the eye, optic nerve damage, and vision loss are not all required to diagnose glaucoma. However, a diagnosis of glaucoma is almost certain when all three of these criteria are present.
