"Our study is the first to reveal the protective effect of metformin on the development of AMD," lead investigator Yu-Yen Chen said in a statement. "While more study is required to determine just how metformin protects against the development of AMD, this is an exciting development for patients at risk."
The scientists noted AMD is the one of the leading causes of blindness in Americans over age 50, and it affects about 2.1 million people worldwide. It occurs when part of the retina called the macula is damaged. While doctors do not yet fully understand how it develops, they believe smoking, diet and systemic diseases like heart disease can be factors.
The researchers now hope to continue their evaluations to better understand how metformin can be used to ward off the eye illness.
