Doctor's Notes on Glaucoma FAQs

Glaucoma is an eye disease in which an increase in eye pressure causes damage to the optic nerve that may result in peripheral or central visual loss. Most types of glaucoma are due to elevated pressure inside the eye, called intraocular pressure (IOP). Angle-closure glaucoma, in which the normal drainage canals within the eye are physically blocked and open-angle glaucoma, in which the drainage system remains open are the two main types of glaucoma. Glaucoma tends to run in families and is more prevalent as people get older. People with diabetes, uncontrolled high blood pressure (hypertension), those who are nearsighted or farsighted or who have a history of certain eye conditions are at higher risk of developing glaucoma.

Most people with glaucoma do not experience symptoms until they have lost a significant amount of vision. Vision loss is permanent. When symptoms of acute angle-closure glaucoma occur include pain, redness, haloes, and blurred vision.
