What does periorbital ecchymosis commonly indicate?

Periorbital ecchymosis, often described as bruising around the eyes, is commonly known as "raccoon eyes." This condition typically indicates potential trauma to the skull, such as a skull fracture. When there is significant force applied to the head, blood vessels around the eyes can break, leading to the characteristic bruising.

While conditions like conjunctivitis, corneal abrasion, and sinus infections may cause eye-related symptoms, they do not typically manifest with periorbital ecchymosis. Conjunctivitis involves inflammation of the conjunctiva and generally does not produce bruising. A corneal abrasion pertains to the surface of the eye and is usually accompanied by pain and visual disturbances, rather than bruising. Sinus infections may cause pressure or swelling but are not associated with the type of bruising observed with skull fractures. Therefore, in the context of periorbital ecchymosis, the identification of a skull fracture is the most pertinent and appropriate interpretation.
