Diabetic Retinopathy Vitrectomy
Proliferative Diabetic Retinopathy
Cause: Abnormal blood vessel growth and scarring from diabetes, which may bleed or pull on the retina.
When vitrectomy is needed:
- Non-clearing vitreous hemorrhage
- Tractional retinal detachment threatening the macula
- Fibrovascular proliferation causing traction
- Often preceded by intravitreal anti-VEGF
- Non-clearing vitreous hemorrhage
Procedure:
- Anesthesia: Often general due to complexity.
- Three-port pars plana vitrectomy setup.
- Core vitreous and hemorrhage removed with vitrector.
- Induce posterior vitreous detachment (PVD) if not already present.
- Dissect fibrovascular membranes that are pulling on the retina (often tightly adhered).
- May require scissors or segmentation tools.
- May require scissors or segmentation tools.
- Diathermy (cauterization) may be used to stop active bleeding.
- Pan-retinal photocoagulation (laser) is applied to reduce ischemia and neovascular drive.
- Tamponade:
- Gas if there’s retinal traction.
- Oil if complex or reoperation likely.
- Gas if there’s retinal traction.
- Ports removed, wounds examined for leaks or bleeding.
Goal: Stop bleeding, relieve pulling on retina, prevent detachment.
Success Rate: Good if done early (anatomical success ~80–90%).
Risks: Recurrent bleeding, scar tissue growth, glaucoma.
Side Effects: Cataract, visual recovery varies.
