Macular edema is the leading cause of vision loss in the increasingly frequent occurrence of diabetes mellitus, a true epidemic in developed countries. Diabetic macular edema is closely related to lifestyle, obesity, smoking or high blood pressure. Macular oedema is the leading cause of vision loss in people with diabetes in developed countries, and its prevalence is directly related to the duration of diabetes. Its incidence varies from publication to publication, ranging between 7.5% and 15.2%, and is more common in patients with type 2 diabetes receiving insulin.The significance of the incidence of diabetic macular oedema is directly related to the patient's metabolic control and the presence of risk factors, as we will see below.
