In The USA Scientists Have Found The New Causes Of Glaucoma.
Glucosamine supplements that millions of Americans subtract to servant scrutinize up on and knee osteoarthritis may have an unexpected side effect: They may enlarge risk for developing glaucoma, a small new study of older adults suggests in May 2013. Glaucoma occurs when there is an heighten of intraocular compel (IOP) or pressure inside the eye bonuses. Left untreated, glaucoma is one of the influential causes of blindness.

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

So "This study shows a reversible effectuate 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 plausibility that stable wreck can result from prolonged use of glucosamine supplementation is not eliminated. Monitoring IOP in patients choosing to augment with glucosamine may be indicated".

Exactly how glucosamine supplements could select pressure inside the eye is not fully understood, but several theories exist. For example, glucosamine is a harbinger for molecules called glycosaminoglycans, which may elevate look pressure. The findings are published online May 23 as a examine missive in JAMA Ophthalmology.

The study had some shortcomings. Researchers did not have tidings on the dose or brand of glucosamine used, and they did not know how long some participants were taking the supplements. Duffy MacKay, frailty president for scientific and regulatory affairs at the Council for Responsible Nutrition, a Washington, DC-based clientele society representing supplement manufacturers, said the findings don't far-out that people should stop taking the supplements.

And "This delve into letter raises questions and introduces a hypothesis that should be explored further, but the miniature number of cases investigated and the fact that researchers did not number capsules or control for dose or intake or duration of use of glucosamine specify extremely limited evidence of harm. This inspect should not change consumer habits; however, individuals with glaucoma or ocular hypertension who are taking glucosamine should let their treat know so that the appropriate monitoring of intraocular insist upon measurements can be done to identify any changes.

MacKay concluded: "The proficient news is that increased IOP was reversible. So if you select the product, and your IOP goes up, then you can stop taking the product to imagine if it returns to normal". However, previous studies have raised questions about whether glucosamine supplements yield any health benefit to consumers.

A bountiful recent study concluded it had no healing effect on arthritic pain. The developing relationship between glucosamine and glaucoma is restored to Dr Scott Fudemberg, a glaucoma surgeon at Wills Eye Institute, in Philadelphia. "The approach about how people can ripen glaucoma isn't completely understood, so how the supplements may conduct a role isn't completely understood either.

While the study found an linkage between taking glucosamine and increased eye pressure, it didn't establish a cause-and-effect relationship. The best fashion that anyone can do to preserve their vision is to get legitimate eye exams, Fudemberg advised. "Glaucoma can be treated with medications, lasers and/or surgery. These findings pretence a suspect about whether oral glucosamine can raise intraocular eye pressure, but it doesn't victual an answer weight loss. More research is now needed before any conclusions can be drawn.
