Glaucoma is a leading cause of blindness in the U.S. It occurs when the pressure inside the eye rises, damaging the optic nerve and causing vision loss. The condition often develops over many years without causing pain or other noticeable symptoms – so you may not experience vision progressed.
Sometimes symptoms may occur including:

|
Glaucoma (Primary Open Angle) |
Glaucoma (Narrow Angle) |
Why is it important to raise awareness about glaucoma?
People often are unaware that glaucoma has no symptoms in its early stages. The prevalence data is staggering, and its numbers are on the rise.
If detected early, before noticeable vision loss occurs, glaucoma can usually be controlled. Vision lost from glaucoma cannot be restored.
Anyone can get glaucoma, but those at higher risk include:
How is glaucoma detected?
Glaucoma is detected through a comprehensive dilated eye exam that includes the following:
Can glaucoma be cured?
No. There is no cure for glaucoma. Vision lost from the disease cannot be restored.
Glaucoma Treatments
Immediate treatment for early-stage, open-angle glaucoma can delay progression of the disease. That’s why early diagnosis is very important.
Glaucoma treatments include medicines, laser trabeculoplasty, conventional surgery, or a combination of any of these. While these treatments may save remaining vision, they do not improve sight already lost from glaucoma.
Loss of Vision
If you have lost some sight from glaucoma, ask your eye care professional about low vision services and devices that may help you make the most of your remaining vision. Ask for a referral to a specialist in low vision. Many community organizations and agencies offer information about low vision counseling, training, and other special services for people with visual impairments.

Anyone can get glaucoma, but those at higher risk include:
- African Americans age 40 and over
- Everyone over age 60, especially Hispanics/Latinos
- People with a family history of the disease
How is glaucoma detected?
Glaucoma is detected through a comprehensive dilated eye exam that includes the following:
- Visual acuity test. This eye chart test measures how well you see at various distances.
- Visual field test. This test measures your peripheral (side vision). It helps your eye care professional tell if you have lost peripheral vision, a sign of glaucoma.
- Dilated eye exam. In this exam, drops are placed in your eyes to widen, or dilate, the pupils. Your eye care professional uses a special magnifying lens to examine your retina and optic nerve for signs of damage and other eye problems. After the exam, your close-up vision may remain blurred for several hours.
- Tonometry is the measurement of pressure inside the eye by using an instrument called a tonometer. Numbing drops may be applied to your eye for this test. A tonometer measures pressure inside the eye to detect glaucoma.
- Pachymetry is the measurement of the thickness of your cornea. Your eye care professional applies a numbing drop to your eye and uses an ultrasonic wave instrument to measure the thickness of your cornea.
Can glaucoma be cured?
No. There is no cure for glaucoma. Vision lost from the disease cannot be restored.
