Glaucoma is the leading cause of blindness in the U.S. However, if it is detected and treated early, blindness or severe loss of vision can be prevented. Glaucoma occurs when pressure in the eyeball increases. If not detected and treated early, pressure damages the delicate optic (eye) nerve. If one is fortunate, glaucoma can be detected and treated before there is a build-up of pressure in the eye or eyes.

For unknown reasons, in glaucoma the fluid which bathes the eye and nourishes nearby tissues, drains out of the eye too slowly. As the fluid builds up, the pressure in the eye rises. The greater the pressure that builds up in the eye, the greater the damage to the optic nerve. Unless the pressure is controlled, it may damage the optic (eye) nerve and other parts of the eye. This disorder is more common in African-Americans and Latinos than in the general population.

Key Risk Factors for Glaucoma:

above 40 years of age
family history
being African-American (significantly increased risk)
having diabetes
