Subtenon's local anesthesia for optic nerve sheath fenestration.
OBJECTIVE
We used subtenon's local anesthesia for optic nerve sheath fenestration as an alternative to either general or retrobulbar anesthesia.


METHODS
Thirty patients with pseudotumor cerebri, who were unresponsive to medical treatment, underwent optic nerve sheath fenestration after administration of topical and subtenon's local anesthesia.


RESULTS
When topical tetracaine, in conjunction with subtenon's anesthesia, was administered at the beginning of the procedure, excellent anesthesia and maximal patient comfort were achieved.


CONCLUSIONS
The use of local anesthesia allows for a pain-free, expeditious operation with fewer potential anesthetic complications.
