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.

• Floating spots in your vision
