Glaucoma | Diagnosis & Tests


How do I know if I have glaucoma?

You won't know you have glaucoma until you notice vision loss. Since glaucoma usually causes no symptoms other than vision loss, it is important that you have a complete eye exam by an ophthalmologist regularly. An ophthalmologist is a doctor who is trained to provide care for the eyes, including the diagnosis and treatment of glaucoma. Your ophthalmologist can measure your eye pressure, examine your optic nerve and evaluate your central and peripheral vision. Early diagnosis and treatment of glaucoma can prevent damage to the eye's nerve cells and prevent severe vision loss.

How often should I have an eye exam?

People 18 to 60 years of age should have an eye exam every 2 years. After age 60, you should have an eye exam once a year.
