In The USA Scientists Have Found The New Causes Of Glaucoma

In The USA Scientists Have Found The New Causes Of Glaucoma.
Glucosamine supplements that millions of Americans grab to relieve treat informed and knee osteoarthritis may have an unexpected side effect: They may increase risk for developing glaucoma, a tight-fisted new study of older adults suggests in May 2013. Glaucoma occurs when there is an expand of intraocular pressure (IOP) or pressure inside the eye. Left untreated, glaucoma is one of the unrivalled causes of blindness.

In the new study of 17 people, whose average age was 76 years, 11 participants had their lustfulness pressure measured before, during and after taking glucosamine supplements. The other six had their percipience pressure measured while and after they took the supplements. Overall, pressure inside the perspicacity was higher when participants were taking glucosamine, but did return to normal after they stopped taking these supplements, the study showed.

So "This swotting shows a reversible effect of these changes, which is reassuring," wrote researchers led by Dr Ryan Murphy at the University of New England College of Osteopathic Medicine in Biddeford, Maine. "However, the feasibility that perennial damage can result from prolonged use of glucosamine supplementation is not eliminated. Monitoring IOP in patients choosing to codicil with glucosamine may be indicated".

Exactly how glucosamine supplements could affect squeezing inside the eye is not fully understood, but several theories exist. For example, glucosamine is a vanguard for molecules called glycosaminoglycans, which may elevate eye pressure. The findings are published online May 23 as a experiment with letter in JAMA Ophthalmology.

Treat Glaucoma Before It Is Too Late

Treat Glaucoma Before It Is Too Late.
Alan Leighton discovered he had glaucoma when he noticed a gray square footage of eyesight in his left eye. That was in 1992. "I think about I had it a long time before that, but I didn't know until then," said Leighton, 68, a corporate treasurer who lives in Indianapolis. "Glaucoma is as if that. It's sneaky".

Leighton made an nomination with his ophthalmologist to see what was wrong. "We went for a bunch of tests, and he predetermined there was an issue with that eye, and that I had normal pressure glaucoma".

His response was unsentimental and pragmatic: His forefathers has a history of glaucoma, so the news wasn't a total surprise. "I firm that we needed to take the most proactive methods we could. I would go to the best people I could find and consult what methods they had to address it and keep it from getting worse. I wanted to keep it from affecting my right eye, which was extent clear. I didn't know what the process was going to be to actually stop the glaucoma or trouble it, if it was even possible. I don't know if there was a lot of emotion involved. It was more like, 'Hey, what can we do about this?'".

He asked if there was any means to restore the sight he'd lost, and the answer was no. "They fairly much said that gray area in my left eye was going to stay there, and there was no opening to do any procedures to effectively change that. It had something to do with the optic nerve".

New Method Of Treatment Glaucoma

New Method Of Treatment Glaucoma.
Contact lenses that transport glaucoma medication over hanker periods are getting closer to reality, say researchers working with laboratory animals. In their study, the lenses delivered the glaucoma soporific latanoprost (brand name Xalatan) continuously to animals for a month. It's hoped that some heyday such lenses will replace eye drops now worn to treat the eye disease, the researchers said Dec 2013.

Glaucoma Is Attacking The US Population

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".
