How can we help?
Glaucoma [glaw-KOH-muh] is the name for a group of diseases that can cause vision loss and blindness due to a damaged optic nerve. Having high eye pressure or high blood pressure can both lead to glaucoma. Some people can tolerate high eye pressure better than others, so it may or may not cause glaucoma in your eyes.
Glaucoma can also occur without increased eye pressure. The disease is more common for some groups of people, such as:
The best way to find glaucoma is to visit an eye doctor and have a comprehensive eye exam. Eyedrops and other treatments can help prevent the onset of the condition. Regular eye visits are important because glaucoma may not initially have any symptoms. There may be no pain or loss of vision if the condition stays untreated. After more time passes, tunnel vision or a complete loss of vision may occur.
Glaucoma is different than other eye conditions like cataracts or macular degeneration. If you have cataracts, a thin film will develop over your cornea and make it harder to see. Macular degeneration is vision loss that occurs as you age, and your sharp central vision grows weaker. These conditions can all be diagnosed after an eye exam.

Treatment is very successful at keeping glaucoma from getting worse. However, about 15 out of 100 people treated with the condition will become blind in at least one eye during the next 20 years.
Go to an emergency department if you experience the symptoms of acute-angle glaucoma. See a doctor as soon as possible if you notice the symptoms of open-angle glaucoma.
Since glaucoma has so few symptoms, you should have regular check-ups with your eye doctor to ensure that you aren’t developing the condition. See an eye doctor at least once every 4 years if you are over the age of 40. Go every 2 years if you know you have a family history of the condition or are older than 65 years.
