Preseptal cellulitis
Preseptal Cellulitis
Preseptal cellulitis (pronunciation: pre-sep-tal sel-yoo-LIE-tis) is an infection of the eyelid and surrounding skin, which is located anterior to the orbital septum.
Etymology
The term "preseptal" is derived from the Latin words "prae" meaning "before" and "septum" meaning "partition", referring to the location of the infection before the orbital septum. "Cellulitis" is derived from the Greek word "kellis" meaning "cell" and the Latin word "itis" meaning "inflammation", referring to the inflammation of the skin cells.
Related Terms
- Orbital Cellulitis: An infection located posterior to the orbital septum, often considered more severe than preseptal cellulitis.
- Orbital Septum: A thin membrane that separates the preseptal and orbital spaces of the eye.
- Eyelid: The thin fold of skin that covers and protects the eye.
- Inflammation: The body's response to injury or infection, characterized by redness, warmth, swelling, and pain.
Symptoms
Preseptal cellulitis typically presents with redness, swelling, and warmth of the eyelid. Pain and tenderness are also common. Unlike Orbital Cellulitis, preseptal cellulitis does not typically cause bulging of the eye (proptosis), limited eye movement, or vision changes.
Causes
Preseptal cellulitis is most commonly caused by a bacterial infection, often following a minor injury to the eyelid such as a scratch or insect bite. It can also occur as a complication of a sinus infection or other upper respiratory infection.
Treatment
Treatment for preseptal cellulitis typically involves antibiotics to clear the infection. In severe cases, hospitalization may be required.
