title: Peribulbar anesthesia: one versus two injections.
abstract: OBJECTIVE
  The authors describe their prospective, randomized study of a single peribulbar injection into the junction of the lateral third and medial two thirds of the lower lid compared with the standard two-injection peribulbar technique.
  
  
  METHODS
  One hundred twenty patients undergoing elective intraocular surgery were randomly allocated to receive either one or two injections of a mixture of balanced salt solution, 2% lidocaine, 0.5% bupivacaine, and hyaluronidase. Preoperative akinesia was assessed following the injections. At the end of surgery, the patients were asked if they had experienced any pain or discomfort during surgery.
  
  
  RESULTS
  There was no significant difference in pain or globe akinesia between the two groups.
  
  
  CONCLUSIONS
  The single peribulbar injection was found to be as effective as the standard two-injection peribulbar technique.
