A class of cholesterol-lowering drugs known as statins have demonstrated usefulness in a complication of diabetes called diabetic macular edema (DME). A study conducted of over one hundred individuals with type 2 diabetes with eye complications revealed a lower incidence of the disorder in people who were on a statin compared to those who were not. Statins did not seem to help with the progression of the eye condition, but may help prevent it from occurring.
DME is a complication of poorly controlled blood sugar resulting in the weakening of the blood vessels in the eyes. The vessels can become leaky and result in fluid collection. The fluid interferes with the macula, the part of the eye that allows for sharp vision. DME is a serious condition but can be prevented if caught early.
