raccoon eye appearance
EMERGENCY MEDICINE, SIGNS & SYMPTOMS
A descriptive term for bilateral periorbital accumulations of blood and other substances, likened to the facial mask of a raccoon, a nocturnal North American omnivore, Procyon lotor. This Panda bear-like appearance classically occurs in periorbital haematomas associated with anterior-posterior displacement-
type automobile accidents or basilar fractures of the skull. Less often, the descriptor is applied to the periorbital purpura due to skin infiltration in primary amyloidosis as a spontaneous event, or after prolonged eye-strain.
Note: Children with rhinitis have a similar appearance known as allergic shiners or “bags under the eyes”
Synonyms Black eyes, raccoon eyes
