Combined Antioxidant Therapy on Oxidative Stress, Mitochondrial Dysfunction Markers in Diabetic Retinopathy

Summary

The present study aims to support previous research on antioxidant therapy effects in diabetic retinopathy outcome. The investigators intend to assess 180 patients with diabetic retinopathy in different stages (moderate, severe and proliferative), whom either will be assigned to placebo group or combined antioxidant therapy. Each group will receive the intervention for 12 months. Such intervention consists in taking one tablet (placebo or antioxidant therapy) orally, a day. At baseline, blood and urine samples will be collected in order to assess metabolic and oxidative stress status, mitochondrial function or dysfunction, liver and kidney function. In addition, fluorescein angiography will be done for the categorization of diabetic retinopathy. After six months and at the end of the intervention, blood and urine measurements as well as angiographies will be done for comparing the outcomes between both groups and correlate oxidative stress status, mitochondrial dysfunction with grade of retinopathy.
