Summary
This study found a modified peribulbar anesthesia technique effectively achieves ocular akinesia for intraocular surgery. This safe and efficient method avoids the need for a separate facial block.
Area of Science:
- Ophthalmology
- Anesthesiology
Background:
- Peribulbar anesthesia is a common technique for intraocular surgery.
- Optimizing injection techniques can improve efficacy and patient outcomes.
Purpose of the Study:
- To evaluate a modified single-injection peribulbar anesthesia technique.
- To assess the efficacy and safety of this technique for intraocular surgery.
Main Methods:
- A modified single-injection peribulbar anesthesia technique was administered to 150 eyes.
- Lid anesthesia, lid akinesia, and extraocular muscle akinesia (lateral, inferior, superior, medial rectus) were timed post-injection.
Main Results:
- Complete lid anesthesia was achieved in all 150 eyes.
- Excellent ocular akinesia was achieved in 32.7% of eyes.
- Complete akinesia was achieved in under five minutes in successful cases.
- An injection repeat was necessary in 8% of cases.
Conclusions:
- The modified single-injection peribulbar anesthesia is an effective and safe technique.
- This method eliminates the need for a separate facial block for routine intraocular procedures.
