Diabetic Retinopathy known as common diabetic eye disorder occurs due to the change in retina blood vessels. Sometimes these vessels swell and leak fluid or even close off completely. Diabetic retinopathy may eventually cause blindness. Diabetic Retinopathy usually affects both the eyes.
Diabetic Retinopathy can be categorized into four main stages:
Pre- proliferative Proliferative
The tiny blood vessels can be damaged because of high quantity of sugar in the blood. These blood vessels nourish the retina. The blood supply to the retina is cutoff, as more and more blood vessels become blocked which may result in vision loss. Because of the shortage of blood supply, the body attempts to grow new blood vessels but as a result these new blood vessels don’t develop properly, which again becomes a reason for vision loss.
Diabetic retinopathy will not have symptoms during initially. When the symptoms become noticeable, the condition is often at an advanced stage. At times the only detectable symptom is an unexpected and complete loss of vision.
If the eye ailment progresses then diabetic retinopathy signs can include:
Dark strings or spots floating in vision
Dark portions due to vision
Loss of sight
Shadows or missing areas of vision
Difficulty due to color perception

The only way patients with diabetes can protect themselves by attending every eye examination their doctor tells them to do.
If diabetic retinopathy is detected at early stage then it becomes difficult to treat. However, advanced retinopathy needs eye medications, injections or the laser treatments.

Diabetic retinopathy should be diagnosed and treated at early stage to avoid or prevent blindness. It generally starts without any noticeable change in the vision. An eye doctor (ophthalmologist) can detect the signs or symptoms. Hence, it is important for diabetic patients to have an eye examination at least once annually. Also, to reduce the risk of developing retinopathy following steps should be followed:
Annual screening appointment Medication as prescribed
Do not smoke
Exercise regularly Inform the doctor immediately if any changes are noticeable in vision
The best way to avoid diabetic retinopathy is to keep good control over blood sugar and blood pressure. Vision loss can be reduced by treatments but it does not cure diabetic retinopathy or reverse the changes that have already occurred.
