Whether diabetic retinopathy develops depends in part on how high blood sugar levels have been and how long they have been above a target range. Our providers may not see and/or treat all topics found herein. The early stages of retinal damage are called nonproliferative retinopathy. First, tiny blood vessels called capillaries in the retina develop weakened areas in their walls called microaneurysms.
