Case in brief
A 48-year-old woman with end-stage renal disease had a cardiac arrest during hemodialysis and received 24 minutes of CPR, with return of spontaneous circulation. Brain CT incidentally showed a 2.6 × 2.4 × 1.2 cm acute subperiosteal hematoma along the right orbital roof, displacing the superior rectus inferiorly. She had mild proptosis and upper-eyelid swelling, but normal intraocular pressure and no relative afferent pupillary defect; blood counts and coagulation results were normal. With no clinical evidence of orbital compartment syndrome, the hematoma was managed conservatively. She died 24 hours later after a recurrent arrest due to myocardial infarction.
What made this case unusual
The report describes non-traumatic subperiosteal orbital hemorrhage after CPR, with the authors proposing transient intrathoracic pressure increases during chest compressions as a possible association.
Diagnostic / clinical pearl
New proptosis or periorbital swelling after CPR should prompt ophthalmic assessment for orbital hemorrhage and signs of sight-threatening compartment syndrome.
