If you have glaucoma, the intraocular pressure in the eye is elevated beyond a safe level.

If glaucoma is left untreated, patients can permanently lose their vision.

People don't experience glaucoma symptoms until the disease is quite advanced. Once a patient begins to get vision loss, it's already too late to reverse the damage.

Glaucoma is typically painless.

People who are most likely to develop glaucoma have a family history of it, have a short eye with a narrow anterior chamber, or have a genetic condition.
