Risk factors associated with diabetic retinopathy

The risk factors for diabetic retinopathy

include diabetes duration, blood sugar control, hypertension, nephropathy, and other factors such as pregnancy, hyperlipidemia, smoking, cataract surgery, obesity, and anemia. In particular, the longer the diabetes duration, the worse the metabolic indicators such as blood sugar, blood pressure, and lipids are controlled, the more likely diabetic retinopathy is to occur.
