Glaucoma Is Attacking The US Population.
The changing makeup of the US citizenry is expected to usher to an increase in cases of glaucoma, the leading cause of vision forfeiture in the country, experts say. A number of demographic and health trends have increased the covey of Americans who fall into the major risk groups for glaucoma. These trends include: the aging of America, tumour in the black and Hispanic populations, the ongoing obesity epidemic.
And as more people become at risk, standard eye exams become increasingly important, eye experts say. Early detection of glaucoma is elemental to preserving a person's sight, but eye exams are the only way to catch the contagion before serious damage is done to vision. "The big thing about glaucoma is that it doesn't have any signs or symptoms," said Dr Mildred Olivier of the Midwest Glaucoma Center in Hoffman Estates, Ill, and a meals colleague of Prevent Blindness America.
And "By the time someone says, 'Gosh, I have a problem,' they are in the end stages of glaucoma," Olivier said. "It's already charmed most of their sight away. That's why we convene glaucoma 'the sneak thief of sight.'"
Glaucoma currently affects more than 4 million Americans, although only half have been diagnosed, according to the Glaucoma Research Foundation. It's cited as the cause of 9 to 12 percent of all cases of blindness in the United States, with about 120000 subjects blinded by the disease.
Glaucoma is most often caused by an broaden in the rational fluid pressure inside the eye, according to the US National Eye Institute. The added urging damages the optic nerve, the bundle of more than a million nerve fibers that shoot signals from the eye to the brain. In most cases, people first notice that they have glaucoma when they begin to fritter their peripheral vision.
By then, it's too late to save much of their eyesight. "Glaucoma is the count one cause of irreversible but avoidable blindness," said Dr Louis B Cantor, chairman and professor of ophthalmology at the Indiana University School of Medicine and cicerone of the glaucoma service at the Eugene and Marilyn Glick Eye Institute in Indianapolis. "By the stretch it's noticeable, 70 to 90 percent of sight for sore eyes has been lost," he said. "Once it's gone, it's gone. There's no retrieving plan lost to glaucoma".
The most common risk factor for glaucoma is simply surviving. "Glaucoma is a malady of aging," Cantor said. "The risk of developing glaucoma goes up considerably with aging". As the citizens of the United States ages, the number of glaucoma cases will result increase. As Olivier said, "We're just going to have more people who are older and living longer, so we'll have more glaucoma".
