Diabetic Retinopathy

What is Diabetic Retinopathy?

Diabetic retinopathy, the most common diabetic eye disease, occurs when blood vessels in the retina change. Sometimes these vessels swell and leak fluid or even close off completely. In other cases, abnormal new blood vessels grow on the surface of the retina.

It is the most common cause of blindness in western nations between age group of 20-40 years and very important evolving cause of blindness in India.It is associated with the growing incidence of diabetes in India.

What are causes of diabetic retinopathy?

When blood sugar levels are too high for extended periods of time, it can damage capillaries (tiny blood vessels) that supply blood to the retina. Over time, these blood vessels begin to leak fluids and fats, causing swelling. Eventually, these vessels can close off.

Symptoms of diabetic retinopathy

You can have diabetic retinopathy and not be aware of it, since the early stages of diabetic retinopathy often don't have symptoms.As the disease progresses, diabetic retinopathy symptoms may include:

  • Blurred vision.
  • Vision that changes periodically from blurry to clear.
  • Blank or dark areas in your field of vision.
  • Poor night vision.
  • Colors appear washed out or different.
  • Vision loss.

Diabetes can cause vision in both eyes to change, even if you do not have retinopathy. Rapid changes in your blood sugar alter the shape of your eye's lens, and the image on the retina will become out of focus. After your blood sugar stabilizes, the image will be back in focus. You can reduce episodes of blurred vision by maintaining good control of your blood sugar.
