Statin therapy was shown to be associated with a decreased risk of diabetic retinopathy in patients with type 2 diabetes and dyslipidemia, according to a study published in JAMA Ophthalmology.
The population-based cohort study used the National Health Insurance Research Database to identify patients with type 2 diabetes and dyslipidemia.
A total of 219,359 Taiwanese patients were selected for the study. Of these patients, 199,760 were in the statin group and 19,599 were in the non-statin group and after propensity score matching, 18,947 patients were analyzed in each group.
Researchers evaluated the exposure period to measure the medication possession rate for the statin. A medication possession rate of 80% or higher was required for the statin group.
“Statin frequency and dosage were obtained, and the intensity for each statin was calculated as low, moderate or high intensity according to the 2013 American College of Cardiology/American Heart Association guideline,” Eugene Yu-Chuan Kang, MD, researcher at the Department of Ophthalmology, Chang Gung Memorial Hospital, Linkou Medical Center, and colleagues wrote.
