—Peribulbar anesthesia, in which local anesthetic is injected outside the muscle cone, has been cited by proponents as having the advantages of greater ease of performance and a lower rate of globe perforation. Rates of globe perforation were low for both techniques in a series of 2000 cases of peribulbar anesthesia in which no globe perforations were reported1 and a series of 4000 cases of retrobulbar anesthesia in which three globe perforations were reported.2 To our knowledge, there are no published case reports of globe perforation after peribulbar injection.

No difficulty was experienced during
