Glucosamine Supplements Tied to Eye Risk
Seniors taking them had side effect that has been linked to glaucoma, small study finds
The potential relationship between glucosamine and glaucoma is new to Dr. Scott Fudemberg, a glaucoma surgeon at Wills Eye Institute, in Philadelphia. "The mechanism about how people can develop glaucoma isn't completely understood, so how the supplements may play a role isn't completely understood either," he said.
While the study found an association between taking glucosamine and increased eye pressure, it didn't establish a cause-and-effect relationship.
The best thing that anyone can do to preserve their vision is to get regular eye exams, Fudemberg advised. "Glaucoma can be treated with medications, lasers and/or surgery," he said. "These findings pose a question about whether oral glucosamine can raise intraocular eye pressure, but it doesn't provide an answer. More research is now needed before any conclusions can be drawn."
