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

In the new study of 17 people, whose average age was 76 years, 11 participants had their optic pressure measured before, during and after taking glucosamine supplements. The other six had their liking pressure measured 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 study showed.

So "This swatting 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 likelihood that constant damage can result from prolonged use of glucosamine supplementation is not eliminated. Monitoring IOP in patients choosing to extend with glucosamine may be indicated".

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

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

And "This research letter raises questions and introduces a hypothesis that should be explored further, but the insufficient number of cases investigated and the fact that researchers did not count capsules or restraint for dose or intake or duration of use of glucosamine provide extremely limited evidence of harm. This observe should not change consumer habits; however, individuals with glaucoma or ocular hypertension who are taking glucosamine should let their cut know so that the appropriate monitoring of intraocular pressure measurements can be done to identify any changes.

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

A large recent contemplate concluded it had no healing effect on arthritic pain. The potential relationship between glucosamine and glaucoma is additional to Dr Scott Fudemberg, a glaucoma surgeon at Wills Eye Institute, in Philadelphia. "The apparatus about how people can develop glaucoma isn't completely understood, so how the supplements may put a role isn't completely understood either.

While the study found an association between taking glucosamine and increased perspicacity pressure, it didn't establish a cause-and-effect relationship. The best thing that anyone can do to preserve their vision is to get bona fide eye exams, Fudemberg advised. "Glaucoma can be treated with medications, lasers and/or surgery. These findings predicate a question about whether oral glucosamine can raise intraocular eye pressure, but it doesn't supply an answer recommended site. More research is now needed before any conclusions can be drawn.
