Periorbital cellulitis

Preseptal cellulitis

 

Periorbital cellulitis is an infection of the eyelid or skin around the eye.

Causes

 

Periorbital cellulitis can occur at any age, but more commonly affects children younger than 5 years old.

This infection can occur after a scratch, injury, or bug bite around the eye, which allows germs to enter the wound. It can also extend from a nearby site that is infected, such as the sinuses.

Periorbital cellulitis is different than orbital cellulitis, which is an infection of the fat and muscles around the eye. In contrast to periorbital cellulitis, orbital cellulitis is a dangerous infection that can cause lasting problems and deeper infections.

 

Symptoms

 

Symptoms include:

  • Redness around the eye or in the white part of the eye
  • Swelling of the eyelid, whites of eyes, and surrounding area

This condition usually does not affect vision or cause eye pain.

 

Exams and Tests

 

Your health care provider will examine the eye, especially, eye movements and test for vision, and ask about the symptoms.

Tests that may be ordered include:

  • Blood culture
  • Complete blood count (CBC)
  • CT scan
  • MRI scan

 

Treatment

 

Antibiotics are given by mouth, by shots, or through a vein (intravenously; IV) to help fight the infection.

 

Outlook (Prognosis)

 

Periorbital cellulitis almost always improves with treatment. In rare cases, the infection spreads into the eye socket, resulting in orbital cellulitis.

 

When to Contact a Medical Professional

 

Contact your provider right away if:

  • The eye becomes red or swollen
  • Symptoms get worse after treatment
  • Fever develops along with eye symptoms
  • It is difficult or painful to move the eye
  • The eye looks like it is sticking (bulging) out
  • There are vision changes.
