Study Objective:
To determine the incidence and contributing factors of complications for patients receiving regional ophthalmic anesthesia.
Design:
Retrospective analysis.
Setting:
Tertiary-care eye center.
Measurements:
Anesthesia records of ophthalmic blocks performed from January 2003 to June 2009 were reviewed. The frequency of block-related complications and details of each complication were recorded.
Main Results:
A total of 33,363 peribulbar blocks were performed, with a total incidence of 0.12% (41 cases). These complications may be divided into systemic complications, 18 cases (0.053%) and needle-related complications, 23 cases (0.068%).
Conclusion:
Peribulbar block complications were rare. In this series, experience of caregivers and axial and needle length were not contributing factors.
