Diabetic retinopathy symptoms
It is not uncommon to suffer from diabetic retinopathy without being aware of it. Indeed, it is rare for people who have the condition to detect symptoms in the initial stages of diabetic retinopathy. Diabetic retinopathy, which usually damages both eyes, has a number of symptoms during its development. These include:
- Blurred or inconsistent vision
- Vision loss or incomplete eyesight
- Colour perception problems
- Darkness in vision
- Dark strings or spots in vision
- Difficulty with color perception
Causes of diabetic retinopathy
Diabetic retinopathy is not an uncommon complication for people with diabetes. The condition is caused by the high levels of blood glucose. This can damage the tiny blood vessels in the retina, the light sensitive cells at the back of the eye. The blood vessels can eventually become blocked, cutting off the blood supply to the retina.
As a result, the eye tries to grow new blood vessels but these don’t develop properly and may leak, causing a loss of vision. In some cases, scar tissue may form on the retina causing it to detach.
Treating and preventing diabetic retinopathy
People with diabetic retinopathy may not need treatment right away. When the condition is still in the initial stage, good control of blood glucose levels can slow down the progression of diabetic retinopathy. It’s important to visit an eye doctor frequently so he or she can closely monitor your eyes and determine if you need treatment.
When diabetic retinopathy is in an advanced stage, surgical treatment may be necessary. Surgery can slow down the progression of diabetic retinopathy but it is definitely not a cure. Diabetes is a lifelong condition, so people who have it should always pay close attention to their eyesight and have eye exams frequently.
