    Study Notes

    Vitrectomy

    • Vitrectomy is the removal of all or part of the vitreous gel (body) in the eye.
    • In a broader sense, vitrectomy surgery can also involve the excision and removal of:
      • Fibrotic membranes
      • Epiretinal membranes
      • Electrocoagulation of bleeding vessels

    Normal Vitreous Gel

    • In its normal state, the vitreous gel is transparent.

    Disease States

    • In certain disease states, bleeding from damaged or newly formed vessels may cause the vitreous to become opaque.
    • Opaque vitreous can severely decrease vision.
    • The surgeon is unable to visualize the retina and treat the underlying pathologic condition before permanent damage occurs.

    Indications for Vitrectomy Surgery

    • Vitrectomy surgery is indicated to:
      • Restore the patient's vision
      • Allow the surgeon to institute treatment if indicated
      • Relieve underlying pathologic processes leading to decreased vision

    Formation of Membranes

    • Formation of membranes can block the visual axis and cause decreased vision.
    • Contraction of these membranes may produce traction-type or rhegmatogenous retinal detachment (RD).
