According to the International Diabetes Federation in 2013, approximately 382 million people currently suffer from diabetes across the world. Diabetic retinopathy is the most common complication of diabetic that affects eyes. People suffering from diabetes type I and II have risk of developing diabetic retinopathy.

Retina is thin layer of light sensitive tissue at the back of the eye. In initial stages diabetic retinopathy may not show any symptoms and later may lead to severe vision loss. Proliferated and non-proliferated are the major stages of diabetic retinopathy. Proliferated diabetic retinopathy is the most dangerous stage. Proliferated diabetic retinopathy has the risk of detachment or hemorrhage into the vitreous leading to severe vision loss. Diabetic retinopathy is treated by many ways depending upon the stage of diabetic retinopathy.

In the U.S., diabetic retinopathy affected around 4.1 million people, while vision-threatening retinopathy was estimated to have affected 899,000 people, in 2010. Diabetic retinopathy is treated with the help of medications and surgeries such as vitrectomy. In addition, control in levels of diabetes is also essential for the treatment of diabetic retinopathy.
North America dominates the global market for diabetic retinopathy due to large number of aging population.
