Diabetic retinopathy is a disease that affects the retina, can be considered a complication in disease evolution and, if it is not detected, can cause serious vision problems. It occurs as a result of damage that high levels of sugar exert on the blood vessels, these can dilate and increase their permeability, producing fumes of their content or they can be partially or totally narrowed, preventing the blood from circulating normally. At first, diabetic retinopathy may have no symptoms or only mild vision problems, but in its evolution, if not properly controlled, it can lead to irreversible vision loss and blindness.
