In advanced cases of diabetic retinopathy, laser treatment has been shown to reduce the loss of vision. The surgery does not cure diabetic retinopathy, nor does it prevent future vision loss, especially if diabetes or blood pressure is not well controlled.
Diabetes can also affect your vision by causing cataracts and glaucoma. If you have diabetes, you may get cataracts at a younger age and your chances of developing glaucoma are doubled.
Early diagnosis of diabetes and effective control of blood sugar and hypertension through diet, exercise and medication can help to reduce your risk of developing eye diseases associated with diabetes.
