title: Globe perforation associated with subtenon's anesthesia.
abstract: OBJECTIVE
  To report a case of globe perforation while initiating posterior subtenon's anesthesia.
  
  
  METHODS
  Case report. A 40-year-old man with a history of retinal detachment in both eyes presented for repair of a second retinal detachment in the LE.
  
  
  RESULTS
  Upon dissecting a space beneath the Tenon capsule with scissors, the globe was perforated.
  
  
  CONCLUSIONS
  In patients with prior ophthalmologic surgery, thinned sclera, or excess scar tissue, increased caution should be employed during initiation of sub-Tenon anesthesia or an alternative method should be used.
