MetS is the main risk factor for diabetes mellitus, which is associated with vascular changes in the retina. However, the early consequences of MetS in the retina are not well described. We therefore aimed at characterizing the early effects of a high fructose and high fat diet HFHF on the function and structure of the rat retina, and evaluate the associations with metabolic changes. Brown Norway rats of 6 weeks of age were fed for 8 days, 5 weeks or 13 weeks with HFHF diet, or a standard chow. After only 4 weeks of this diet, rats exhibited a reduction in cone photoreceptor sensitivity to light. These retinal abnormalities were associated with deregulation of glucose metabolism but not lipid metabolism. Metabolic syndrome MetS appears to be a risk factor for the development of Diabetic Retinopathy DR 1 and Age-related Macular Degeneration AMD 2, which are the leading causes of visual impairment in western populations before and after the age of 50 years, respectively 3. Associated with lifestyle changes, i. Met is characterized by a cluster of abnormalities like dyslipidaemia, hyperglycaemia, insulin resistance, hypertriglyceridaemia, hypertension, and an excess of abdominal fat 4.
