Glaucoma is the general name for a group of common diseases that affect the eyes and can result in blindness if not diagnosed and treated promptly.
Chronic open-angle glaucoma is the most common form of glaucoma and is due to gradually increasing pressure inside the eye (intraocular pressure). Increased intraocular pressure inside the eye results from a malfunctioning canal that does not allow the clear fluid inside the eye to drain properly. The high pressure inside the eye can eventually damage the optic nerve leading to permanent vision loss and eventually blindness. There may be no symptoms in early stages of chronic open-angle glaucoma, but without treatment, the damage to the optic nerve result in blind spots, which progressively become bigger until blindness occurs.
Acute closed-angle glaucoma is less common than chronic open-angle glaucoma and is a medical emergency. Acute closed-angle glaucoma is the result of a sudden and severe increase in intraocular pressure due to a blockage by the iris, the colored part of the eye. Symptoms of acute closed-angle glaucoma occur suddenly and can rapidly lead to blindness if not treated emergently. Symptoms include blurred vision and severe eye pain. For more information on symptoms and complications, refer to symptoms of glaucoma.
Glaucoma can affect anyone, but some factors contribute to the risk of developing the condition. These include a family history of diabetes or glaucoma or being nearsighted or being over age 60. People of African ancestry who are over the age of 40 years are also at risk for developing glaucoma.
Glaucoma is diagnosed through a combination of taking a medical history, including symptoms, and eye examination by an ophthalmologist, a physician who specializes in eye care. The eye examination can include a variety of tests. These include a visual acuity test to check the sharpness of vision. A visual acuity test involves reading an eye chart located at a specific distance across the room.
A visual field test checks sight on the peripheral (side) areas of vision. A tonometry test that measures pressure inside the eye is performed using an instrument called a tonometer. The ophthalmologist will also use eye drops to enlarge the pupil of the eye so that he and she can look directly into the eye with an instrument called an ophthalmoscope and see the retina and optic nerve.
A gonioscopy test may also be done. In this test a special lens is placed on the eye to examine the channel in the eye that drains eye fluid to see if it has become blocked or has other abnormal changes.
Because there are often no symptoms in early stages of glaucoma, a diagnosis can be delayed or missed. In addition, symptoms of glaucoma can be similar to symptoms of other diseases or conditions. For more information on misdiagnosis and diseases and conditions that can mimic glaucoma, refer to misdiagnosis of glaucoma.

The first step in the treatment of glaucoma is the prevention of progression of the disease and permanent serious complications, such as blindness. This includes seeking regular eye care throughout the lifetime. This can help detect chronic open-angle glaucoma in early stages before symptoms appear. In addition, it is vital to seek immediate emergency medical care if ...Glaucoma Treatments

Glaucoma (glaw-KOH-muh) starts from pressure building up in the eye. Over time, this pressure damages your eye's main nerve--the optic nerve. The damage first causes you to lose sight from the sides of your eyes. (Source: excerpt from Keep your eyes healthy: NIDDK)
Glaucoma is another common eye disease. This is the result of too much fluid pressure inside the eye. It can lead to vision loss and blindness. The cause of glaucoma is unknown. African-American women over the age of forty are at particular risk for glaucoma, as are all women over 60. If treated early, glaucoma often can be controlled and blindness prevented. To find glaucoma, the eye doctor will look at your eyes through dilated pupils. Treatment may be prescription eye drops, oral medications, or surgery. Most people with glaucoma have no early symptoms or pain from increased pressure. (Source: excerpt from Aging -- Women Getting Older: NWHIC)
