It may be easy to see that beauty is deeply rooted in your family tree. But some things that are passed down from generation to generation are not as easily seen—like glaucoma.
Glaucoma, an eye disease that runs in families and often has no warning signs, is actually a group of diseases that damages the eye’s optic nerve, which carries visual signals to the brain. It can lead to vision loss or blindness, if left untreated.
Primary open-angle glaucoma is the most common form of this disease. Quite often, by the time people are diagnosed with glaucoma they have already begun to notice changes in their side, or peripheral, vision. It’s important not to wait until you notice vision problems to see your eye care professional.
“Studies show that at least half of all persons with glaucoma don’t know they have this potentially blinding eye disease,” said National Eye Institute (NEI) director Dr. Paul Sieving. “The good news is that glaucoma can be detected in its early stages through a comprehensive dilated eye exam.”
People with a family history of glaucoma and everybody at higher risk—especially African Americans age 40 and older—should get a comprehensive dilated eye exam every 1 to 2 years.
A comprehensive dilated eye exam is a procedure in which an eye-care professional places drops in your eyes to dilate (or widen) the pupil to examine the back of your eyes and your optic nerve for signs of disease. This exam may help save your sight because when glaucoma is detected early, it can be controlled through medications or surgery.
