The Eye Foundation: Your Guide to High-Risk PDR and Vitreo-Retinal Treatment

What is High-Risk PDR?

Proliferative diabetic retinopathy (PDR) is a severe stage of diabetic retinopathy, a complication of diabetes that affects the eyes. High-risk PDR is a particular form of PDR characterized by rapid progression and a high risk of vision loss.

Characteristics of High-Risk PDR

High-risk PDR is defined by specific features that indicate a heightened risk of vision loss. These features include:

  • Extensive new blood vessels (neovascularization) on the surface of the retina or optic nerve
  • Vitreous hemorrhage, bleeding within the gel-like substance that fills the eye
  • Preretinal hemorrhage, bleeding between the retina and the vitreous
  • Large areas of neovascularization (NVE) greater than half the size of the optic disc

Risks of High-Risk PDR

High-risk PDR poses a significant threat to vision due to the potential for:

  • Vitreous hemorrhage: Bleeding into the vitreous can obscure the retina, leading to severe vision loss or blindness.
  • Tractional retinal detachment: As new blood vessels contract, they can pull on the retina, causing it to detach. Retinal detachment can lead to permanent vision loss if not promptly treated.

Treatment for High-Risk PDR


Timely and effective treatment is crucial for managing high-risk PDR and preventing vision loss. The primary treatment options include:

  • Anti-VEGF injections: These injections inhibit the growth of new blood vessels, reducing the risk of bleeding and vision loss.
  • Panretinal photocoagulation (PRP): This laser treatment aims to shrink new blood vessels and reduce their risk of bleeding.
  • Vitrectomy: In severe cases with vitreous hemorrhage or retinal detachment, surgery may be necessary to remove blood from the vitreous or repair the detached retina.
