By examining the cornea of the eye with a special microscope it may be possible within ten minutes to diagnose if a person with type 2 diabetes has nerve damage. This according to a study among diabetics in Skelleftea, north Sweden.
Type 2 diabetic can lead to impaired nerve function, half of those who have had type 2 diabetes for more than ten years have a decrease in nerve functions, which usually begins in their feet. The decrease may be expressed as reduced sensibility or pain and increases the risk of wounds. Sometimes the reduction can also cause the need for an amputation. There is currently no cure for this type of nerve damage, and the methods available so far at clinics to diagnose the condition are not entirely optimal.
