New Method Of Treatment Glaucoma.
Contact lenses that announce glaucoma medication over dream of periods are getting closer to reality, say researchers working with laboratory animals. In their study, the lenses delivered the glaucoma upper latanoprost (brand name Xalatan) continuously to animals for a month purchase. It's hoped that some broad daylight such lenses will replace eye drops now hand-me-down to treat the eye disease, the researchers said Dec 2013.

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 deduct to helper treat informed and knee osteoarthritis may have an unexpected side effect: They may increase risk for developing glaucoma, a unimportant new study of older adults suggests in May 2013. Glaucoma occurs when there is an development of intraocular pressure (IOP) or pressure inside the eye vimax. Left untreated, glaucoma is one of the peerless causes of blindness.
In the new study of 17 people, whose average age was 76 years, 11 participants had their discrimination pressure measured before, during and after taking glucosamine supplements. The other six had their knowledge pressure measured while and after they took the supplements keppra common side effects. Overall, pressure inside the visual acuity was higher when participants were taking glucosamine, but did return to normal after they stopped taking these supplements, the study showed.
So "This reading 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 prospect that immutable damage can result from prolonged use of glucosamine supplementation is not eliminated. Monitoring IOP in patients choosing to postscript with glucosamine may be indicated".
Exactly how glucosamine supplements could affect make inside the eye is not fully understood, but several theories exist. For example, glucosamine is a herald for molecules called glycosaminoglycans, which may elevate eye pressure. The findings are published online May 23 as a examination 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 yard of discern in his left eye. That was in 1992. "I over 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 groove on 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 ascertained there was an issue with that eye, and that I had normal pressure glaucoma".
His response was unsentimental and pragmatic: His subdivision has a history of glaucoma, so the news wasn't a total surprise. "I stony that we needed to take the most proactive methods we could. I would go to the best people I could find and woo 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 somewhat 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 fashion to restore the sight he'd lost, and the answer was no. "They unbelievably much said that gray area in my left eye was going to stay there, and there was no occasion to do any procedures to effectively change that. It had something to do with the optic nerve".

Glaucoma Is Attacking The US Population
Glaucoma Is Attacking The US Population.
The changing makeup of the US populace is expected to actress to an increase in cases of glaucoma, the leading cause of vision ruin in the country, experts say. A number of demographic and health trends have increased the numeral of Americans who fall into the major risk groups for glaucoma. These trends include: the aging of America, increase in the black and Hispanic populations, the ongoing obesity epidemic.
And as more people become at risk, steady eye exams become increasingly important, eye experts say. Early detection of glaucoma is leading to preserving a person's sight, but eye exams are the only way to catch the complaint 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 embark on fellow 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 captivated most of their sight away. That's why we title 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 forebears blinded by the disease.
Glaucoma is most often caused by an broaden in the routine fluid pressure inside the eye, according to the US National Eye Institute. The added lean on 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 mislay their peripheral vision.
By then, it's too late to save much of their eyesight. "Glaucoma is the calculate 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 foreman of the glaucoma service at the Eugene and Marilyn Glick Eye Institute in Indianapolis. "By the fix it's noticeable, 70 to 90 percent of dream has been lost," he said. "Once it's gone, it's gone. There's no retrieving scheme lost to glaucoma".
The most common risk factor for glaucoma is simply surviving. "Glaucoma is a c murrain of aging," Cantor said. "The risk of developing glaucoma goes up considerably with aging". As the natives of the United States ages, the number of glaucoma cases will logically increase. As Olivier said, "We're just going to have more people who are older and living longer, so we'll have more glaucoma".
