Questions and Answers

What is the primary purpose of using silicone oil in patients with complicated retinal tears and detachment?

  • To hold the retina down with its weight (correct)
  • To prevent inflammation in the eye
  • To facilitate easier vision recovery

  • Supine position for most of the day
  • On their side to allow free movement
  • Upright to reduce discomfort
  • Facedown for 22 out of 24 hours (correct)
  • Why are antibiotics administered prophylactically in certain eye procedures?

  • To improve the healing of macular holes
  • To manage postoperative pain effectively
  • To enhance the stability of gas bubbles
  • To reduce the likelihood of endophthalmitis (correct)

    Study Notes

    Surgical Techniques and Complications

    • Tools are used to release traction and lift the Internal Limiting Membrane (ILM).
    • Silicone oil can be introduced into the eye for patients with complicated retinal tears and detachment, helping to keep the retina in place through its weight.
    • Gas bubbles are inserted into the eye to ensure surgical attachment of the retina at the repair site, commonly employed in macular hole repairs.

    Pharmacological Interventions

    • Prophylactic antibiotics may be prescribed to lower the risk of endophthalmitis.
    • Steroids assist in managing inflammation and promote wound healing during recovery.

    Postoperative Care

    • Patients may require strict postoperative positioning, often needing to remain facedown for up to 22 hours daily, which can be challenging.

    Vision Considerations

    • Elevated intraocular pressure (IOP) can lead to vision damage, necessitating careful management of central and peripheral vision post-repair.
    • Visual Acuity (VA) may be reduced due to inflammation or the presence of a gas bubble obstructing the view.

    Complications and Conditions

    • A Posterior Subcapsular Cataract (PSC) often develops following a Pars Plana Vitrectomy (PPV).
    • Hyphema, or blood in the anterior chamber, can occur alongside retinal procedures.

    Types of Endophthalmitis

    • Bacterial endophthalmitis arises from infections, while sterile endophthalmitis is associated with excessive ocular inflammation without an infectious cause.
    • Prostaglandins, such as latanoprost, are avoided postoperatively due to their pro-inflammatory properties.
