Retrobulbar block: a review for the clinician

Area of Science:

• Ophthalmology
• Anesthesiology

Background:

• Cataract surgery is increasingly performed in outpatient settings.
• Advances in surgical techniques have improved patient safety and outcomes.
• Retrobulbar block has emerged as a preferred anesthetic method over general anesthesia.

Purpose of the Study:

• To provide a comprehensive overview of retrobulbar block for cataract surgery.
• To detail the anatomical considerations, pharmacological agents, and procedural techniques.
• To discuss the potential complications associated with retrobulbar block.

Main Methods:

• Review of anatomical structures relevant to retrobulbar injection.
• Discussion of anesthetic agents used in retrobulbar block.
• Description of the step-by-step technique for administering the block.
• Analysis of potential complications and their management.

Main Results:

• Retrobulbar block provides effective anesthesia and akinesia for cataract surgery.
• Specific anatomical landmarks are crucial for safe and effective injection.
• Common complications include retrobulbar hemorrhage, globe perforation, and optic nerve injury.
• Proper technique and patient selection minimize risks.

Conclusions:

• Retrobulbar block is a safe and effective anesthetic technique for outpatient cataract surgery.
• Understanding the anatomy, pharmacology, and technique is essential for minimizing complications.
• This method offers advantages over general anesthesia in the ambulatory setting.
