Black eye

Black eye Classification and external resources
Illustrative of a "black eye".
ICD-10	S00.1
ICD-9	921.0

A black eye (periorbital hematoma) is bruising around the eye commonly due to an injury to the face rather than an eye injury. The name is given due to the color of bruising.

When bilateral, it is also known as raccoon eyes.^[1]

[edit] Presentation and prognosis

Close-up of a black eye after a few days of formation. The blood has been absorbed, but the iron-laden pigments in the blood remain in the tissue leaving a discolouration that may persist from months to a lifetime

Most black eye injuries are minor and will heal themselves in about one week. Trauma near the eyebrow or places not directly on the eye may make the eyelid go black.

The dramatic appearance (discoloration purple black and blue and swelling) does not necessarily indicate a serious injury. The fatty tissue along with the lack of muscle around the eye socket allows a potential space for blood accumulation with relatively minor injury. As this blood is reabsorbed, various pigments are released similar to a bruise, lending itself to the extreme outward appearance. Unless there is actual trauma to the eye itself, medical attention is generally not needed.^{[citation needed]}

[edit] Associated conditions

Eye injury and head trauma may also coincide with a black eye. Some common signs of a more serious injury may include:

• Double vision
• Loss of sight and or fuzzy vision
• Loss of consciousness
• Inability to move the eye or large swelling around the eye such as a hematoma
• Blood or clear fluid from the nose or the ears
• Blood on the surface of the eye itself or cuts on the eye itself
• Persistent headache

[edit] Treatment

Putting a raw steak on a black eye (an old wives' tale) has long been known to have no medicinal value. Putting potentially bacteria-laden meat on a mucous membrane or an open skin injury can be dangerous.^[2]

Treatment for the black eye can include ice, heat, and anti inflammatory medication.

If it was a severe blow that caused the black eye (something more than just bumping into a door), blowing one's nose could increase inflammation. Sometimes the injury fractures the bone of the eye socket, and blowing one's nose can force air out of the sinus adjacent to the socket. The air gets injected under the skin and makes the eyelids swell even more. It can also increase the chance of infection.^[3] Keep the head elevated (sleep with a few extra pillows, for example) to help limit swelling and pooling.
