=== Description === | === Description === | ||
Raccoon eyes refer to bruising around the eyes that resemble the mask-like patterns seen in raccoons. This condition arises due to bilateral hemorrhage, often as a result of facial fractures that tear the meninges, leading to bleeding from the venous sinuses into the arachnoid villi and cranial sinuses. In simpler terms, blood from a skull fracture seeps into the soft tissues around the eyes. | Raccoon eyes refer to bruising around the eyes that resemble the mask-like patterns seen in raccoons.

Raccoon Eyes (Periorbital Ecchymosis)[edit]

Description[edit]
Raccoon eyes refer to bruising around the eyes that resemble the mask-like patterns seen in raccoons. This condition arises due to bilateral hemorrhage, often as a result of facial fractures that tear the meninges, leading to bleeding from the venous sinuses into the arachnoid villi and cranial sinuses. In simpler terms, blood from a skull fracture seeps into the soft tissues around the eyes.
Associated Conditions[edit]
Raccoon eyes are commonly associated with:
- Basal skull fractures
- Subgaleal hematoma
- Post-cranial surgery complications
In rare instances, they may also signal the presence of certain cancers.
Diagnosis and Symptoms[edit]
The appearance of raccoon eyes typically occurs within 48 to 72 hours after an injury. They may present alongside Battle's sign, which is an ecchymosis (bruising) behind the ear. These signs can sometimes be the sole indicators of a skull fracture, as the fracture may not be visible on an X-ray.
Medical Advice and Precautions[edit]
It is recommended that individuals with raccoon eyes should avoid blowing their nose or coughing vigorously to prevent further complications. Medical attention is essential for proper diagnosis and treatment.
