Doctors sometimes call raccoon eyes periorbital ecchymosis. "Periorbital" means "around the eyes." "Ecchymosis" is a change in color.
Raccoon eyes can appear after an injury or illness that causes tiny blood vessels to bleed into the skin under the eyes. They're not the same as the dark circles you get when you're tired. Those dark circles are much more mild and aren't from a medical condition.
Raccoon eyes are a symptom, not a disease. They aren't dangerous themselves, but they could be a sign of a serious head or eye injury. Consult a doctor, and do that right away if you’ve recently had an injury.
What Causes Them?
Raccoon eyes are usually a symptom of an injury to the eyes or head. Injuries can stretch and tear tiny blood vessels called capillaries under your eyes. Blood leaks into the skin and turns it a dark purple color. Because the skin under your eyes is very delicate, even a minor injury can cause a lot of blood to pool underneath.
Raccoon eyes can also be a symptom of certain systemic conditions, but that’s not the most likely case.
They can happen with primary amyloidosis, a disease that causes an abnormal protein to build up in tissues around the body. Primary amyloidosis can weaken blood vessels so much that a strong sneeze or cough is enough to break them.
Other diseases that weaken or stretch the blood vessels can also cause raccoon eyes, including:
- Eye aneurysm
- Blood clot in the sinuses
- Giant cell arteritis
- Migraine and other headaches
- Increased pressure in the brain
Some cancers have raccoon eyes as one of their symptoms, including:
What Else You Might Have
Which other symptoms you have depends on the condition that caused your raccoon eyes. Other symptoms of a skull fracture include:
- A lump or swelling on the head
- Confusion or dizziness
- Nausea or vomiting
- Bruising behind the ear
- Clear fluid draining from your nose or ears
Amyloidosis causes symptoms like these:
Treatments for Raccoon Eyes
The skin problem itself probably doesn’t need treatment. But if you had a head injury, you’ll need medical help right away.
You might need a computed tomography (CT) scan to look for signs of injury in your brain. You may need surgery for a severe fracture or other head injury to remove a clot, fix broken blood vessels, or remove broken pieces of bone. And if you had a concussion, that needs medical care and rest. Most skull fractures will also heal by themselves, but the process can take a few months.
Raccoon eyes should go away on their own, although it can take up to 2 weeks. It's normal for the color to change from purple to green or yellow as you heal. That's the blood reabsorbing into your skin. Apply ice packs to your closed eyes to bring down any swelling.
