Summary
Posterior peribulbar anesthesia offers a safer alternative to retrobulbar anesthesia for intra-ocular surgery. This technique reduces risks by depositing anesthetic outside the muscle cone, achieving comparable anesthesia and akinesia.
Area of Science:
- Ophthalmology
- Anesthesiology
Background:
- Retrobulbar anesthesia, while effective for intra-ocular surgery, carries risks due to proximity to ocular nerves and vessels.
- Potential complications include retrobulbar hemorrhage and globe perforation.
Purpose of the Study:
- To describe the posterior peribulbar anesthesia technique as a safer alternative.
- To evaluate its efficacy in achieving anesthesia and akinesia for intra-ocular procedures.
Main Methods:
- The posterior peribulbar anesthesia technique involves depositing local anesthetic outside the ocular muscle cone.
- This method was applied in over 400 cases undergoing intra-ocular surgery.
Main Results:
- Posterior peribulbar anesthesia significantly reduces the risks associated with retrobulbar injections.
- The technique provides equivalent levels of anesthesia and akinesia compared to the retrobulbar route.
Conclusions:
- Posterior peribulbar anesthesia is a safe, effective, and easier alternative for intra-ocular surgery.
- It minimizes potential dangers while ensuring adequate surgical conditions.
