Diabetes-related retinopathy
What is Diabetic Retinopathy?
It’s an eye condition that can lead to vision loss and blindness in people with diabetes.
It affects the blood vessels in the retina and the light-sensitive tissue at the back of the eye. High blood sugar levels due to diabetes can damage the retina's blood vessels, causing them to leak fluid or bleed. This can lead to the growth of abnormal blood vessels, which can further contribute to vision problems.
Types of Diabetic Retinopathy
There are two main types of diabetic retinopathy: Non-proliferative diabetic retinopathy (NPDR) and Proliferative diabetic retinopathy (PDR).
NPDR is the early stage of the disease, while PDR is more advanced and can lead to severe vision problems.
Symptoms
In the early stages, diabetic retinopathy often has no symptoms.
As the condition progresses, symptoms may include:
Spots or dark strings floating in your vision (floaters)
Blurred vision
Fluctuating vision
Dark or empty areas in your vision
Vision loss
How is Diabetic Retinopathy Diagnosed?
Dilated fundus exam: Eye doctors check for diabetic retinopathy during a special eye exam. They put drops in your eyes to make your pupils bigger, giving them a better view of the retina.
Optical coherence tomography (OCT): This imaging test uses light to create detailed cross-sections of the retina, helping to detect early signs of diabetic retinopathy, such as swelling or fluid buildup.
Fluorescein angiography: This test involves injecting a dye into your arm and taking pictures of your eye's blood vessels. It can help identify leaking blood vessels and other abnormalities.
Other tests: In some cases, additional tests, such as a visual field test or an electroretinogram, may be needed to assess the extent of vision loss or damage to the retina.
How is Diabetic Retinopathy Treated?
Controlling blood sugar and blood pressure is crucial for preventing the progression of diabetic retinopathy.
Your doctor might prescribe special eye drops to lower eye pressure or treat other eye problems.
Special eye injections can help stop abnormal blood vessels from growing and reduce fluid buildup.
Laser treatment can seal leaking blood vessels and reduce swelling in the retina.
Regular eye exams (annually) are essential for early detection and treatment of diabetic retinopathy.
In advanced cases, surgery may be needed to remove blood or scar tissue from the eye.
Additional Considerations
Lifestyle changes: Maintaining a healthy diet, exercising regularly, and quitting smoking can help prevent or slow the progression of diabetic retinopathy.
Genetic factors: Certain genetic factors may increase the risk of developing diabetic retinopathy.
Trend
In the United States, about 8 million people have diabetic retinopathy, and it's estimated that around 1 million people have had it in the last five years.
Over the next five years, the number of people with diabetic retinopathy is projected to increase due to the rising prevalence of diabetes.
History of Diabetic Retinopathy
Diabetic retinopathy has been a significant concern for individuals with diabetes for many years.
As the number of people with diabetes has increased, so has the prevalence of diabetic retinopathy.
Advances in medical understanding and technology have improved the diagnosis and treatment of this condition, helping to reduce the risk of vision loss for many individuals.
