Subperiosteal orbital hematoma: visual recovery following delayed drainage.
Subperiosteal orbital hematomas are rare sequelae of blunt periorbital trauma. Visual loss in such cases is very infrequent, but reportedly irreversible, unless treated with early decompression. A 17-year-old boy developed marked visual loss secondary to an acutely developing traumatic subperiosteal orbital hematoma. Despite delayed referral surgical evacuation of the hematoma remarkably restored his vision. Postoperative clinical examination, fluorescein angiography, and electrophysiologic testing confirmed that a compressive optic neuropathy had caused the visual dysfunction. Although immediate surgical decompression remains the treatment of choice for subperiosteal hematomas producing visual loss, this case demonstrates that the optic nerve may recover dramatically even after a prolonged period of dysfunction from compression.
