What is Laser Treatment for Nonproliferative Diabetic Retinopathy?

laser-treatment-diabetic-retinopathy

In nonproliferative diabetic retinopathy (NPDR), leaking blood vessels can cause macular edema and loss of vision. The goal of laser in NPDR is to stop the leakage and prevent further vision loss. In proliferative diabetic retinopathy (PDR), neovascularization can cause severe loss of vision by bleeding (vitreous hemorrhage) and by developing scar tissue that can pull on the retina and cause a retinal detachment. The goal of laser in PDR is to stop the growth of new blood vessels and prevent these complications.
