Black eyes, medically known as periorbital ecchymosis, commonly indicate a head injury. This condition occurs when blood vessels around the eyes break, often due to trauma, leading to bruising. The area around the eyes is particularly susceptible due to the thin skin and the presence of a significant blood supply, which facilitates the accumulation of blood beneath the skin following impact.

Identifying a black eye as a potential indicator of head injury is crucial, as such injuries may be associated with more serious conditions, including concussions or skull fractures. Therefore, observing a black eye should prompt further assessment for additional symptoms of head injury, such as confusion, dizziness, or changes in consciousness.

While other conditions like eye infections, allergic reactions, and sinusitis can cause eye-related symptoms, they typically do not present with the distinct bruising associated with trauma. Eye infections may lead to redness or discharge; allergic reactions often cause swelling or itching; and sinusitis may produce pressure or pain around the eyes but not the characteristic dark discoloration indicative of injury.
