Overall, pressure inside the eye was higher when participants were taking glucosamine, but did return to normal after they stopped taking these supplements, the study showed.

"This study 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 possibility that permanent damage can result from prolonged use of glucosamine supplementation is not eliminated.

U.S. News and World Report noted that while this was the first time this link has been made, the study was limited in terms of brand and duration of the supplement.
