Diabetic Retinopathy
Diabetic retinopathy is an
eye problem that can cause
blindness. It occurs when
high blood sugar damages
small blood vessels in the
back of the eye, called the
retina. All people with
diabetes are at risk for this
problem. There are things
you can do to reduce your
risk and prevent or slow
vision loss.

Diabetic retinopathy can affect both eyes. You may not have any signs at
first. As it worsens, blood vessels weaken and leak blood and fluid. As
new blood vessels grow they also leak causing blocks in your vision.
Signs of Diabetic Retinopathy
• Floating spots in your vision
• Blurred vision
• Blocked or hazy vision
Your Care
To help reduce your risk of vision loss:
• Keep your blood sugar levels well controlled. This is one of the best
ways to protect your vision. Work with your doctor, nurse and
dietitian.
• Keep your blood pressure and blood cholesterol levels normal. You
may need to take medicine.
• Have an eye exam each year by an eye specialist that includes eye
dilation. An eye exam can detect early changes before you have any
signs.
• Call your doctor if you have any changes in your vision.
