World Diabetes Day
World Diabetes Day (WDD) was created in 1991 by IDF and the World Health Organization in response to growing concerns about the escalating health threat posed by diabetes. World Diabetes Day became an official United Nations Day in 2006 with the passage of United Nation Resolution 61/225. It is marked every year on 14 November, the birthday of Sir Frederick Banting, who co-discovered insulin along with Charles Best in 1922.
WDD is the world’s largest diabetes awareness campaign reaching a global audience of over 1 billion people in more than 160 countries. The campaign draws attention to issues of paramount importance to the diabetes world and keeps diabetes firmly in the public and political spotlight.
The World Diabetes Day campaign aims to:
- Be the platform to promote IDF advocacy efforts throughout the year.
- Be the global driver to promote the importance of taking coordinated and concerted actions to confront diabetes as a critical global health issue.
The campaign is represented by a blue circle logo that was adopted in 2007 after the passage of the UN Resolution on diabetes. The blue circle is the global symbol for diabetes awareness. It signifies the unity of the global diabetes community in response to the diabetes epidemic.
Every year, the World Diabetes Day campaign focuses on a dedicated theme that runs for one or more years. The theme for World Diabetes Day 2018-19 is Family and Diabetes.
What is diabetic eye disease?
Diabetic eye disease is a group of eye problems that can affect people with diabetes. These conditions include diabetic retinopathy, diabetic macular oedema, cataracts, and glaucoma.
Over time, diabetes can cause damage to your eyes that can lead to poor vision or even blindness. But you can take steps to prevent diabetic eye disease, or keep it from getting worse, by taking care of your diabetes.
The best ways to manage your diabetes and keep your eyes healthy are to
- manage your blood glucose, blood pressure, and cholesterol sometimes called the diabetes ABCs
- If you smoke, get help to quit smoking
- have a dilated eye exam once a year
- Often, there are no warning signs of diabetic eye disease or vision loss when damage first develops. A full, dilated eye exam helps your doctor find and treat eye problems early—often before much vision loss can occur.
How does diabetes affect my eyes?
Diabetes affects your eyes when your blood glucose, also called blood sugar, is too high.
In the short term,
you are not likely to have vision loss from high blood glucose. People sometimes have blurry vision for a few days or weeks when they’re changing their diabetes care plan or medicines. High glucose can change fluid levels or cause swelling in the tissues of your eyes that help you to focus, causing blurred vision. This type of blurry vision is temporary and goes away when your glucose level gets closer to normal.
If your blood glucose stays high over time,
It can damage the tiny blood vessels in the back of your eyes. This damage can begin during prediabetes when blood glucose is higher than normal, but not high enough for you to be diagnosed with diabetes. Damaged blood vessels may leak fluid and cause swelling. New, weak blood vessels may also begin to grow. These blood vessels can bleed into the middle part of the eye, lead to scarring, or cause dangerously high pressure inside your eye.
Most serious diabetic eye diseases begin with blood vessel problems. The four eye diseases that can threaten your sight are
- Diabetic retinopathy
- Diabetic macular edema
