Diabetic retinopathy is a disease that affects small blood vessels of the retina.
The retina is the inner envelope of the eye that helps to transform everything that we see into an impulse that passes along the visual path to the brain, where the final data processing is already taking place and the visual image is created. A healthy retina is necessary for good vision.
Diabetic retinopathy can lead to blockage of blood vessels in the retina, bleeding, and severe visual impairment.
Anyone with type 1 or type 2 diabetes is at risk of developing diabetic retinopathy.
Since diabetic retinopathy does not show any symptoms in its early stages, it can become quite advanced before a person living with diabetes begins to notice it. Regular eye examinations can help detect and treat diabetic retinopathy at an early stage, which should prevent it from progressing to a stage where it is more difficult to treat.
