Glaucoma is actually a group of related eye disorders
They all cause damage to the optic nerve, vitally carrying information from the eye to the brain. Glaucoma is typically associated with high intraocular pressure (IOP), but can also occur when pressure is normal.
Glaucoma usually has few (or no) symptoms — at first
If undiagnosed or untreated, over time, glaucoma eventually causes peripheral vision loss, and can lead to blindness.
Millions have glaucoma
The American Academy of Ophthalmology (AAO), reports that well over two million people in the U.S. have the most common type of glaucoma, primary open-angle (POAG), and about half don’t even realize it. By the year 2020, as the population continues to age, that number is predicted to increase to 3.3 million.
Glaucoma is the second-leading cause of blindness in the U.S.
And it’s the second-leading cause of blindness globally. (Macular degeneration in number one in the U.S.; cataracts are number one worldwide.)
POAG is also called the “silent thief of sight”
That’s because in its early stages, there are no warning signs. People with the disease experience no pain or other symptoms that would indicate a problem. And vision loss occurs once the disease in its later, most serious stages.
Regular eye exams are key
Over time, the pressure on the eye can cause irreversible nerve damage and vision loss, which usually begins with peripheral vision. But routine eye exams can catch the disease in its most early stages, when it’s most treatable.
How an eye examination identifies glaucoma
The doctor checks your IOP and evaluates the optic nerve. If eye pressure is elevated or the optic nerve looks irregular, he or she can perform visual field tests plus scans of the retina and optic nerve, which can help determine the presence of glaucoma.
