Take a closer look at DR
Diabetic retinopathy (DR) and diabetic macular edema (DME) negatively
affect the health of blood vessels and cells in the eye that help you
see. They develop because of diabetes, uncontrolled high blood sugar,
and other factors.
How do DR and DME affect the eyes?
In DR and DME, high blood sugar blocks blood vessels in the eye and damages the retina, leading to problems with vision
New blood vessels grow when blockages occur, but are unhealthy and weak
Blood and fluid leak from the blood vessels into the retina, causing problems with vision
What are the different stages of diabetic retinopathy?
DR can be “early” or “late” stage. DR begins in the early stage called NPDR. Without treatment or controlled blood sugar, DR can advance to the late stage called PDR.
Early stage: Non‐proliferative diabetic retinopathy (NPDR)
- In NPDR, high blood sugar causes damage to small or large blood vessels in the eye. This damages eye cells and leads to problems with vision
- This early stage is called “non‐proliferative” because the eye is damaged, but no new unhealthy blood vessels are growing
Late stage: Proliferative diabetic retinopathy (PDR)
- In PDR, damaged blood vessels close off, and the eye tries to make new blood vessels. However, they leak blood or fluid and lead to problems with vision
- This stage is called “proliferative” because the eye is growing new blood vessels to replace blocked or damaged ones
Why should I talk to my doctor if I have diabetes and vision problems?
If you do not have a Retina Specialist, speak to your primary care
physician, endocrinologist, or ophthalmologist about a referral
