It is common to hear that diabetes may cause complication in the eye and could lead to blindness. This is known as diabetic retinopathy. The development of retinopathy is strongly related to the length of time diabetes has been present and the degree of blood glucose (sugar) control.

Diabetic retinopathy can hurt four parts of the eye:

  1. Retina (REH-it-nuh) – This is the lining at the back of the eye. Its job is to sense light coming into the eye.
  2. Vitreous (VIH-tree-us) – This the jelly-like fluid that fills that back of the eye.
  3. Lens – This is located at the front of the eye and it focuses light on the retina.
  4. Optic Nerve – This is main nerve of the eyes to the brain.

Diabetic Retinopathy is the deterioration of the small blood vessels that nourishes the retina. There are two forms of diabetic retinopathy:

Although the development of retinopathy can cause serious blindness, but only a small percentage of people with diabetic retinopathy lose their sight. So with regular checks and treatment retinopathy-caused blindness can be prevented.
