title: Minimal invasive transcaruncular optic canal decompression for traumatic optic neuropathy.
abstract: Traumatic optic neuropathy is a cause of loss of vision associated with head injuries. Treatment options include observation, steroids and decompression of the optic canal. We report a case where the optic canal decompression was performed using a transcaruncular approach under a regional block. The incision was made through the caruncle and the dissection was carried down to the periosteum down to the orbital apex where the optic nerve was seen exiting through the optic canal posterior to the posterior ethmoidal artery. The optic nerve was decompressed with good visualization. Hemostasis and wound closure was achieved using fibrin glue. Postoperatively visual acuity improved with minimal inflammation enabling early rehabilitation.
