A common diabetes medication may do more than lower blood sugar levels, the Atlanta Journal Constitution reports.
Researchers in Taiwan recently presented a study at an American Academy of Ophthalmology conference to determine the relationship between metformin, a common diabetes medication, and age-related macular degeneration (AMD).
Using the Taiwan National health Insurance Research Database, they examined more than 62,000 patients with type 2 diabetes. About 45,000 of them took metformin, while about 22,000 did not. The analysts followed the groups for 13 years.
They found that people on metformin had a significantly lower risk of developing AMD. In fact, twice as many patients who did not take metformin had the eye condition, compared to those did.
