Diabetic retinopathy is one of the most common complications of type 1 diabetes and types 2 diabetes. A recent study by the American diabetes association has found that fifty percent of people with elevated sugar levels at the pre-diabetes stage are at risk.
What is diabetic retinopathy?
Diabetic retinopathy occurs when high sugar levels damage small blood vessels in the retina. You can also go for the best diabetic eye exam online.
The retina is a part of the eye that is sensitive to light and is very important for healthy vision, which is why blindness occurs when the retina is damaged.
Unfortunately, there are few warnings or symptoms before the onset of diabetic retinopathy. That is why all diabetics must undergo eye examinations at least once a year.

Because diabetic retinopathy has four stages, if detected early enough there is a treatment to stop the progression of the disease so that it does not cause blindness.
If you see blood spots or spots floating in your vision, even if it only happens once to go and do an eye test, don't wait for further damage to occur.
Sometimes these spots will disappear without any treatment, but bleeding can occur at night and blurred vision is a possible outcome.
Diabetic retinopathy has four stages:
1. Mild Nonproliferative Retinopathy.
The retina has many small blood vessels and microaneurysms or small swelling occurs.
2. Moderate nonproliferative retinopathy.
This swelling gets worse until they block blood vessels to the retina.
3. Severe Nonproliferative Retinopathy.
Clogged vessels become more swollen which rob some of the retinal areas from their vital blood supply, to compensate for the retina asking the brain to grow more blood vessels
