This means that tiny bulges (microaneurysms) have appeared in the blood vessels in the back of your eyes (retina), which may leak small amounts of blood. This is very common in people with diabetes.

Stage 2: pre-proliferative retinopathy

This means that more severe and widespread changes are seen in the retina, including bleeding into the retina.

Stage 3: proliferative retinopathy

This means that new blood vessels and scar tissue have formed on your retina, which can cause significant bleeding and lead to retinal detachment (where the retina pulls away from the back of the eye).

At this stage:
