Diabetic retinopathy refers to the vision problems that sometimes occurs with diabetes. It is the result of the overgrowth of capillaries in the retinas that precludes light and images from reaching the optic nerves. The symptoms in a patient’s vision include seeing dark spots, dark strings, impaired color, blurry objects, fluctuating images, empty areas, and eventually developing blindness. The risk factors include suffering from diabetes for a long time, hypertension, high cholesterol, pregnancy, and smoking. Treatments include managing blood sugar levels, laser treatment, surgery, and injectable medication.
