The proliferation which occurs is a growth of new vessels from the surface of the retina on to the surface of the vitreous jelly. This is an attempt at healing the retina in order to compensate for the loss of blood vessels that occurs as part of diabetic retinopathy.

In most cases the proliferation, that is growth of new blood vessels is identified at a regular sight test before any harm has been done. The patient is then offered laser treatment in order to control the growth of the new vessels. In most people that is the end of the problem, however in others despite timely and adequate laser problems with haemorrhage or traction may arise in the future. It is important to realise that proliferative retinopathy is a risky condition and that laser greater reduces but does not completely get rid of the risk of either haemorrhage or tractional detachment.
