Newswise — Did you know that diabetes is the number one cause of preventable vision loss and blindness? Did you also know that an annual eye exam can lead to early detection of diabetic retinopathy and other eye disease, a frequent complication of diabetes?

On Diabetes Alert Day, March 27 -- a day set aside by the American Diabetes Association to raise public awareness of the rampant incidence of diabetes in our nation -- the care team at the world renowned Joslin Diabetes Center's Beetham Eye Institute reminds the 20.8 million Americans with diabetes to schedule an annual eye exam. Joslin's Beetham Eye Institute clinicians have shown that an annual exam can provide early detection and help prevent or delay 90 percent of cases of vision loss due to diabetic retinopathy. According to the Centers for Disease Control and Prevention, diabetic retinopathy is a leading cause of blindness in adults, resulting in 12,000 to 24,000 new cases of blindness each year.

Diabetic retinopathy, the most common eye disease in people with diabetes, occurs when the small blood vessels in the eye are damaged by high levels of glucose in the blood. Because diabetic retinopathy can progress to advanced stages without the patient knowing it, it is crucial to have annual eye exams to help preserve vision.

Joslin clinicians recommend a three-prong approach to preserving vision:

Maintain excellent A1C levels. (The A1C is a test that measures average blood glucose levels over the 2 to 3 month period before the test.) Keep blood pressure, blood lipids and other health factors in check. Have an annual eye exam.

About DiabetesThe World Health Organization reports that approximately 150 million people worldwide have diabetes, and the number is projected to double by the year 2025. In the United States, diabetes affects an estimated 20.8 million children and adults -- 7 percent of the population. An estimated 14.6 million Americans have been diagnosed, leaving 6.2 million Americans unaware that they have the disease. In addition, 54 million Americans are thought to have pre-diabetes, or elevated blood glucose levels that put them at risk for developing type 2 diabetes. If untreated or poorly treated, diabetes can lead to blindness, kidney disease, stroke, nerve damage and circulation problems that can result in limb amputations.
