Diabetic Retinopathy: Protecting Your Sight with Early Detection and Management
By the Diabetic Retinopathy Team at World Diabetes Centre
Diabetic retinopathy (DR) is a serious eye condition that can lead to vision loss and blindness for people with diabetes. It affects the retina, the light-sensitive tissue at the back of the eye that transmits visual signals to the brain. High blood sugar levels can damage the blood vessels in the retina, causing them to leak fluid or bleed. This damage can also lead to the growth of abnormal new blood vessels, which are fragile and can easily bleed.
Early detection is crucial for preventing vision loss from DR. In the early stages, DR often has no symptoms. This is why regular dilated eye exams are essential for everyone with diabetes. Early detection and treatment can help slow the progression of DR and prevent vision loss.
This blog post will cover:

How can I prevent DR?
By understanding DR and taking steps to manage it, you can help protect your vision and maintain a healthy quality of life.
Understanding the Stages of Diabetic Retinopathy
There are two main stages of DR:
Non-proliferative diabetic retinopathy (NPDR): This is the early stage of DR. In NPDR, the blood vessels in the retina leak fluid or blood. However, there is no growth of new blood vessels.
Proliferative diabetic retinopathy (PDR): This is the more advanced stage of DR. In PDR, new blood vessels grow on the surface of the retina. These new blood vessels are fragile and can bleed into the vitreous, the jelly-like substance that fills the center of the eye.
Diabetic Retinopathy Symptoms
In the early stages, DR often has no symptoms. However, as DR progresses, you may experience some of the following symptoms:
Blurred vision
Seeing floaters (dark spots or squiggly lines that float in your vision)
Poor night vision
Loss of central vision
If you experience any of these symptoms, it is important to see an eye doctor right away.
Diagnosing Diabetic Retinopathy
A dilated eye exam is the only way to diagnose DR. During a dilated eye exam, your eye doctor will put drops in your eyes to widen (dilate) your pupils. This allows them to see the back of your eye more clearly. They will then look for signs of DR, such as leaking blood vessels, new blood vessel growth, or swelling in the retina.
Treatment for Diabetic Retinopathy
There is no cure for DR, but there are treatments that can help slow its progression and prevent vision loss. Treatment options for DR may include:
Blood sugar control: The most important thing you can do to manage DR is to control your blood sugar levels.
Laser treatment: Laser treatment can be used to destroy abnormal new blood vessels or to prevent them from growing.
Eye injections: Anti-VEGF injections can be used to reduce swelling in the retina and to slow the growth of new blood vessels.
Vitrectomy: In some cases, surgery called a vitrectomy may be necessary to remove blood from the vitreous cavity.
Preventing Diabetic Retinopathy
The best way to prevent DR is to control your blood sugar levels. You can also help reduce your risk of DR by:
Getting regular dilated eye exams
Maintaining a healthy weight
Eating a healthy diet
Exercising regularly
Not smoking
If you have diabetes, it is important to be aware of DR and to take steps to protect your vision. By working with your doctor and eye care professional, you can manage your diabetes and prevent vision loss.
