Penetrating globe injury is a possible complication after ocular local anesthesia (including peribulbar and retrobulbar blocks).1- 3 Regional nerve blocks of the face are frequently performed by a variety of physicians, including anesthesiologists, otolaryngologists, and other facial surgeons. We describe a case of penetrating globe injury that occurred during an extraoral infraorbital block due to passage of the needle through the infraorbital canal.

Computed tomography. A, Axial view, showing cross section of both infraorbital canals in the maxillary bone. B, Coronal view, clearly showing the proximal portion of the right infraorbital canal as it enters the orbit. Note that the canal's alignment in this section points to the posterior half of the globe.
