NEI Glaucoma Quiz – save sight

True: In a study funded by the National Eye Institute, researchers at The Johns Hopkins University reported that glaucoma is three to four times more likely to occur in Blacks than in Whites. In addition, glaucoma is six times more likely to cause blindness in Blacks than in Whites.

True: Although glaucoma tends to run in families, a hereditary basis has not been established. If someone in your immediate family has glaucoma, you should have your eyes examined through dilated pupils at least every two years.

True: The early stages of open-angle glaucoma, the most common form, usually have no warning signs. However, as the disease progresses, a person with glaucoma may notice his or her side vision gradually failing.

True: Everyone over age 60 has an increased risk for glaucoma. Other groups at increased risk include Blacks over age 40 and people with a family history of the disease.

True: Although glaucoma cannot be cured, it usually can be controlled by eyedrops or pills, conventional surgery, or laser surgery. Sometimes eye care professionals will recommend a combination of surgery and medication.

True: In glaucoma, for reasons still not completely understood, fluid drains too slowly out of the eye. As the fluid builds up, the pressure inside the eye rises. Unless this pressure is controlled, it may cause damage to the optic nerve and other parts of the eye and loss of vision.

True: An eye examination through dilated pupils is the best way to diagnose glaucoma.
Individuals at increased risk for the disease should have their eyes examined through dilated pupils at least every two years by an eye care professional.

False: People with glaucoma usually do not experience pain from the disease.

False: Vision loss from glaucoma is permanent. However, with early detection and treatment, the progression of visual loss can be slowed, or halted, and the risk of blindness reduced.

False: A measurement of eye pressure by tonometry, though an important part of a comprehensive eye exam, is by itself not sufficient for the detection of glaucoma. Glaucoma is detected most often during an eye examination through dilated pupils. This means drops are put into the eyes during the exam to enlarge the pupils, which allows the eye care professional to see more of the inside of the eye to check for signs of glaucoma. When indicated, a visual field test should also be performed.
