title: Compressive optic neuropathy following use of intracranial oxidized cellulose hemostat.
abstract: A 35-year-old white male sustained head injuries in a motor vehicle accident. He underwent neurosurgical repair of a frontotemporal skull fracture and lacerated left frontal lobe; regenerated oxidized cellulose (Surgicel) was placed into the anterior cranial fossa for hemostasis. Forty-eight hours after surgery he suffered rapid deterioration of vision to no light perception from optic nerve compression. Radiologic and echographic evaluation demonstrated a subperiosteal soft tissue density in the orbital apex consistent with hematoma. At surgery for optic canal decompression, the cellulose hemostat was found in the apex of the left orbit, having migrated through orbital roof fractures, and had apparently caused the compressive optic neuropathy. Decompression resulted in return of vision to the level of counting fingers.
