Diabetic Glaucoma
Unexpected sight loss is more common than you may think. Blindness often happens without prior warning signs and in people unaware they are at risk.
The two most common culprits of unexpected sight loss are diabetes and glaucoma.
These diseases are known as the “sneak thieves of sight” because symptoms may not occur in the early stages.
By the time a person realizes something is wrong, irreversible vision loss often occurs.
Diabetic eye disease is the leading cause of blindness in adults. An average of 55 Americans go blind from the disease each day.
The numbers threaten to rise sharply as diabetes becomes increasingly common due to poor eating habits, infrequent exercise, and an aging population.
One in three children born in the United States five years ago is expected to become diabetic during their lives.
Diabetes causes a partial or complete loss of vision in as many as 70 percent of those who have it. Yet 30 percent of all people who have diabetes don’t even know they have it.
Even people who know they have diabetes downplay the risks they face.
In reality, diabetics will develop serious complications that could lead to loss of sight or a limb, or kidney failure.
Glaucoma, on the other hand, is a group of eye diseases that slowly damage the fine nerves that connect the eye to the brain.
For most people, this damage occurs when the pressure in the eye is too high. When these nerves are damaged, vision loss may result.
Glaucoma is the second-leading cause of blindness in the United States. But like diabetes, not enough people know about it. An estimated 4.2 million Americans have glaucoma, but half are not aware of it.
Diabetes and glaucoma are especially prevalent among blacks and Hispanics.
These groups are believed to have a genetic predisposition to the diseases and are much more at risk than Caucasians.
Others, particularly at risk for glaucoma, are people over 60, those with a family history of glaucoma, diabetics, and the very near-sighted.
The good news for those at risk is that a dilated eye exam can detect the two diseases, and early treatment can prevent vision loss. Vision experts urge at-risk people to have regular eye exams.
Raising awareness of diabetic eye disease and glaucoma is key to preventing unnecessary blindness.
