title: Subtenon's local anesthesia for optic nerve sheath fenestration.
abstract: 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.
