What is diabetic retinopathy?

People with diabetes can have eye problems which are known as diabetic retinopathy. The problem occurs when the blood sugar levels are extremely high which damages the retina blood vessels. The blood vessels will leak and swell. Blood flow may be stopped which makes the situation worse. In some cases, abnormal new blood vessels grow on the retina. All such changes which occur in the eye can affect your vision.

What are the stages of diabetic eye disease?

There are 2 main stages of diabetic eye diseases which are mentioned below:

NPDR (non-proliferative diabetic retinopathy)

NPDR is the early stage of diabetic eye disease. Most of the people with diabetes will have this issue. This problem can make the blood vessels leak and the retina will swell. If the macula swells it is referred to as macular edema. This is the most common type in diabetic people who have lost their vision.

Additionally, the blood vessels in the retina can close off and it is referred to as muscular ischemia. If this happens the blood is not able to reach the macula. Tiny particles can form in the retina which is known as exudates and these can affect the vision greatly. If you have NPDR, then your vision can be blurry.

PDR (proliferative diabetic retinopathy)

PDR is the advanced stage of people with diabetes. The problem happens when the retina has new blood vessels growing in it. It is known as neovascularization. The new blood vessels which are formed can easily bleed in the vitreous.

If the bleeding is less, then you will have a few dark floaters. If the bleeding gets in excess then your vision is blocked greatly.

Additionally, new blood vessels can form scar tissue. In some cases, the scar tissues will lead to problems in the detached retina and even there is a problem with the macula. This issue is extremely serious and it can affect your side and central vision greatly.

What are the symptoms of diabetic retinopathy?

If the vision is affected, you are going to notice the following symptoms which include:

  • Seeing an increasing number of floaters,
  • Having poor night vision
  • Noticing colors appear faded or washed out
  • Having a blurry vision
