Effects of Oral Fenofibrate on Retinal Thickness and Macular Volume

Summary

Lipid levels in the blood are proposed to play a role in the progression of diabetic retinopathy. Lipid levels can be controlled with dyslipidemic drugs, such as fenofibrate. Fenofibrate is known to prevent diabetic microvascular complications by decreasing cholesterol and triglyceride levels. This study aims to investigate the effects of oral fenofibrate on central macular thickness (CMT) and macular volume, as well as on specific biomarkers of endothelial dysfunction (eNOS), inflammation (VCAM-1), and angiogenesis (VEGF) in DR individuals with dyslipidemia.
