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.
