Purpose:
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.
