Statins may protect against diabetic retinopathy

And disease progression was slower in those taking the cholesterol drug, study shows

Patients with type 2 diabetes who take statins for high cholesterol may have a lower risk of developing diabetic retinopathy, a study suggests.

Such patients were 14% less likely to develop retinopathy than patients who were not taking statins, researchers said.

And among those who did develop retinopathy, statin therapy was associated with slower disease progression, according to study, which was led by Dr Eugene Yu-Chuan Kang, a researcher at Chang Gung Memorial Hospital in Taiwan.
