Diabetic Retinopathy

Individuals with diabetes can have an eye ailment called diabetic retinopathy. This is when high glucose levels cause damage to the veins in the retina leading to swelling and leaky veins. These veins can thereby close, preventing blood from passing through them. This phenomenon is termed as “Macular ischemia” which is a form of non-proliferative diabetic retinopathy. Sometimes, the retina has growth of new exudates on it which can cause visual damage. If new blood vessels grow in retina, the condition is called proliferative diabetic retinopathy. This type of retinopathy is serious and can cause visual impairment both on the CNS and PNS.
