A yearly eye examination with dilated pupils makes it possible for an ophthalmologist, an eye doctor, to notice changes before the illness becomes harder to treat. Scientists are testing new means of treating diabetic retinopathy. For more information on eye complications of diabetes and the treatment of these conditions, see the resource list at the end of this hypertext document. Legs and Feet Leg and foot problems can arise in people with diabetes due to changes in blood vessels and nerves in these areas. Peripheral vascular disease is a condition in which blood vessels become narrowed by fatty deposits, reducing blood supply to the legs and feet.
Diabetes also can dull the sensitivity of nerves.
Someone with this condition, called peripheral neuropathy, might not notice a sore spot caused by tight shoes or pressure from walking. If ignored, the sore can become infected, and because blood circulation is poor, the area may take longer to heal. Proper foot care and regular visits to a doctor can prevent foot and leg sores and ensure that any that do appear don't become infected and painful. Helpful measures include inspecting the feet daily for cuts or sore spots. Blisters and sore spots are not as likely when shoes fit well and socks or stockings aren't tight.
