Q

What is proliferative retinopathy?

A

Neovascularization (development of fragile new vessels) seen on the optic disc or along main vascular arcades. During proliferation, fibrous adhesions develop between the vessels and the vitreous. Subsequent contraction of adhesions can result in traction on the retina and retinal detachment. Contraction also tears the new vessels, which hemorrhage into the vitreous.
