Percutaneous removal of traumatic subperiosteal hematoma in the orbit

Purpose: To report a case of traumatic subperiosteal hematoma in the orbit treated by percutaneous removal of the subperiosteal hematoma. Case: A 45-years-old male had subperiosteal hematoma in the left orbit after suffering a bruise to the left orbit. He visited our hospital the next day. Initial corrected visual acuity was counting fingers and intraocular pressure was 33 mmHg in left eye. Percutaneous removal of the hematoma was performed, because of severe exophthalmos and ocular motility disorder, and severe visual loss from disturbance in the optic circulation caused by increased orbital pressure. After the treatment, visual acuity improved to 0.3 and exophthalmos and ocular motility disorder disappeared. Conclusion: This case suggests that early invasive removal of the subperiosteal hematoma, which causes severe visual loss with disturbance in the optic circulation, is needed.
