Jason Y1 - 2021 N1 - T2 - The Atlas of Emergency Medicine, 5e AB - Traumatic exophthalmos typically occurs from blunt orbital trauma causing an intraorbital hematoma that pushes the globe anteriorly. Patients present with periorbital edema, ecchymosis, a marked decrease in visual acuity, and an afferent pupillary defect in the involved eye. The exophthalmos, which may be obscured by periorbital edema, can be better appreciated from a superior view. Visual acuity may be affected by the direct trauma to the eye (retinal detachment, hyphema, globe rupture), compression of the retinal artery, or neuropraxia of the optic nerve.
