Researchers recently studied the use of metformin for AMD and deemed it a potential preventive therapy for the disease.
Researchers found that metformin use was associated with a reduced odds of developing AMD and that this association was dose-dependent. Low to moderate doses of metformin had the greatest benefit.
The researchers concluded that metformin may reduce the odds of AMD development, with low to moderate doses having the largest effect. They cautioned, however, that metformin doesn’t appear to be protective in patients with diabetes and coexisting DR.
