There are three main types of diabetic retinopathy.
These three types are differentiated according to the stage that the condition has reached:
1) Non-proliferative retinopathy: The early stage of the condition characterised by small areas of balloon-like swelling in the retina's tiny blood vessels.
2) Maculopathy oedema: As the condition progresses, the macula (which provides our central vision and is vital for clear, detailed vision) swells, caused by leakage of fluid from the blood vessels of the retina.
3) Proliferative retinopathy: At this advanced stage, when blood vessels in the retina have disappeared, the retina's need for nourishment triggers the growth of new blood vessels. These new vessels are abnormal vessels are fragile, bleed easily and may stimulate abnormal supporting tissues which can result in the retina peeling away form the back of the eye. Severe vision loss and even blindness can result.

During the early stages of the condition there may be no symptoms but as the disease progresses, the following symptoms may present:
- Blurred vision
- Seeing floaters or flashers
- Eye strain
- Headaches
