Caption for page six: How can diabetic retinopathy cause vision loss? Description for page six: Illustrations comparing a healthy eye with an eye affected by diabetic retinopathy. The view with the affected eye is a blurred image with splotches blacked out, indicating how blood leaking across the line of sight is a sign of advanced diabetic retinopathy.

Diabetic retinopathy can damage your eyes before you notice any changes in the way you see. Left untreated, diabetic retinopathy can cause vision loss that cannot be restored.
