What Causes Diabetic Retinopathy?

Chronic high blood glucose caused by Type 1 and Type 2 diabetes is the primary cause of diabetic retinopathy. Constant high blood sugar levels damage the tiny vessels of the retina, causing an inappropriate supply of blood and nutrition to this sensitive area. 

Other risk factors of diabetic retinopathy include:

• High blood pressure (hypertension) 

• Cholesterol 

• Smoking

• Sedentary lifestyle

• Poor dietary choices
