Jason SR Print(0) ID 1181038093 T1 Traumatic Exophthalmos T2 The Atlas of Emergency Medicine, 5e YR 2021 FD 2021 PB McGraw-Hill PP New York, NY SN 9781260134940 LK accessemergencymedicine.mhmedical.com/content.aspx?aid=1181038093 RD 2024/03/29 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.
