Diabetic Retinopathy is one of the most serious . Diabetic Retinopathy is caused from damage to the blood vessels of the retina, which is a layer of tissue located at the back of the inner eye. Its function is to change light and images entering the eye into nerve signals, which reaches the brain and allows us vision.  Damage to the retina occurs of a period of time as high blood pressure and/or high blood sugars which are not controlled cause the tiny blood vessels of the retina to swell and become weak. Over time, these blood vessels become blocked and blood flow to the eye is disturbed or completely cut off. The damage results in slowly progressing vision problem and eventually blindness in one or both eyes.

Studies show that on average 40% of patients with and 20% of patients with are likely to develop diabetic retinopathy.  Diabetic Retinopathy is the leading cause of blindness in working age Americans. Diabetics with uncontrolled diabetes have a significantly higher risk of developing this ocular complication. It should also be noted that nearly all patients of diabetes, who are suffering from the disease for more than 30 years, have signs of diabetic retinopathy.

There are two stages of diabetic retinopathy which are called Non Proliferative Stage and Proliferative Stage.

  • In Non Proliferative stage blood vessels in the eye become larger in certain spots. It is known as micro aneurysms. There may be a blockage in any of the blood vessels in the retina or any amounts of bleeding and fluid leaking into the retina. This bleeding may be caused due to retinal hemorrhages.
  • In proliferative stage of diabetic retinopathy new blood vessels start to grow in the eye that are fragile and can bleed. There may also be small scars on the retina and in other parts of the eye called the vitreous.
