In people with diabetes, out-of-control blood sugar can spell trouble. High blood sugar can lead to a number of problems, including eye damage.

From your head to your toes, diabetes can cause problems throughout the body. Even your eyes can be affected by diabetes.

Over 2.7 million people over 40 years old in the U.S. are affected by glaucoma. New research findings may offer a way those predisposed to the disease can reduce their risk. 

The eyes may be sensitive at times, but they are tough. And new research shows that parts of them may be able to combat diseases.

For the blind, learning the layouts of new places just got a little easier.

Celiac disease (a condition that damages the small intestine) may boost the risk of type 1 diabetes. But that may not be where the damage ends. Celiac disease could lead to problems down the road for diabetes patients.

If you have diabetes, you could end up having problems in many parts of the body, including the heart, kidneys or eyes. If you want to protect yourself against these problems, you may need to keep a closer eye on your cholesterol.

U.S. Food and Drug Administration officials have approved Lucentis ( ranibizumab injection) as the first drug capable of treating a severe eye disease that develops in individuals with diabetes.

Delivering injected medication to the back of the eye for conditions such as age-related macular degeneration (AMD), the leading cause of blindness among older adults, can be challenging for doctors.

Just 25 years ago, nearly a quarter of older adults had difficulty reading a newspaper because of poor eyesight. That number has dropped substantially in recent years.
