Metformin, a common Type 2 diabetes medication, may offer protection against a subtype of age-related macular degeneration (AMD), according to a study published in Investigative Ophthalmology & Vision Science.
This is the latest among other studies suggesting that the medication may have several uses beyond diabetes, such as promoting longevity and weight loss and protecting against neurological disorders, cancer, and cardiovascular disease. Most of the proposed uses are off-label, which means the U.S. Food and Drug Administration (FDA) has not approved the medication to treat those conditions.
