Diabetic Retinopathy
Descriptions
Overview
Diabetic retinopathy (die-uh-BET-ik ret-ih-NOP-uh-thee) is a diabetes complication that affects eyes. It’s caused by damage to the blood vessels of the light-sensitive tissue at the back of the eye (retina).
At first, diabetic retinopathy might cause no symptoms or only mild vision problems. But it can lead to blindness.
The condition can develop in anyone who has type 1 or type 2 diabetes. The longer you have diabetes and the less controlled your blood sugar is, the more likely you are to develop this eye complication.
Symptoms
You might not have symptoms in the early stages of diabetic retinopathy. As the condition progresses, you might develop:
- Spots or dark strings floating in your vision (floaters)
- Blurred vision
- Fluctuating vision
- Dark or empty areas in your vision
- Vision loss
When to see an eye doctor
Careful management of your diabetes is the best way to prevent vision loss. If you have diabetes, see your eye doctor for a yearly eye exam with dilation — even if your vision seems fine.
Developing diabetes when pregnant (gestational diabetes) or having diabetes before becoming pregnant can increase your risk of diabetic retinopathy. If you’re pregnant, your eye doctor might recommend additional eye exams throughout your pregnancy.
Contact your eye doctor right away if your vision changes suddenly or becomes blurry, spotty or hazy.
