Diabetic Retinopathy is one of the most common diabetic eye diseases, which is currently the leading cause of blindness in most adults in the western hemisphere. The condition is brought about by changes in the blood vessels in the retina. In a majority of the reported cases, the blood vessels may swell and start to leak fluids. In other cases, there may be an abnormal growth of new blood vessels on the surface of the retina (the light-sensitive layer at the back of the eye) which may bring about an unhealthy retina, causing poor vision. Patients suffering from diabetic retinopathy will at first notice changes in their vision. However, the condition will get worse in the course of time and lead to loss of vision. The condition usually affects both eyes.
