  "abstract": "Subperiosteal orbital hemorrhage is a rare condition that is typically observed following direct facial or orbital trauma. Non-traumatic subperiosteal orbital hemorrhage (NTSOH) has been infrequently reported in association with sudden elevations in cranial venous pressure or venous congestion. To the best of our knowledge, this is the first reported case of NTSOH associated with cardiopulmonary resuscitation (CPR). A 48-year-old woman with end-stage renal disease developed cardiac arrest while undergoing hemodialysis. CPR was performed for 24 minutes, resulting in the successful return of spontaneous circulation. Contrast-enhanced computed tomography of the brain incidentally revealed a 2.6 × 2.4 × 1.2 cm mixed-density subperiosteal lesion along the roof of the right orbit with a smooth lateral margin, causing inferior displacement of the superior rectus muscle, consistent with an acute subperiosteal hematoma. The patient's coagulation profile and full blood count were within normal limits. Ophthalmic examination demonstrated mild right-sided proptosis and upper eyelid swelling. There was no relative afferent pupillary defect, and the intraocular pressure was within the normal range. A provisional diagnosis of NTSOH was made. Conservative management was pursued, as there were no clinical signs of orbital compartment syndrome. However, the patient died 24 hours later following a recurrent cardiac arrest secondary to myocardial infarction. In conclusion, NTSOH may occur following CPR, possibly associated with transient increases in intrathoracic pressures generated during chest compressions. It should be suspected in patients who develop new proptosis or periorbital swelling following CPR, prompting urgent ophthalmic assessment to identify sight-threatening complications and guide timely clinical management.",
