Periorbital cellulitis

Periorbital cellulitis, (and not to be confused with orbital cellulitis, which is posterior to the orbital septum), is an inflammation and infection of the eyelid and portions of skin around the eye anterior to the orbital septum.[1] It may be caused by breaks in the skin around the eye, and subsequent spread to the eyelid; infection of the sinuses around the nose (sinusitis); or from spread of an infection elsewhere through the blood.

Signs and symptoms

Periorbital cellulitis must be differentiated from orbital cellulitis, which is an emergency and requires intravenous (IV) antibiotics. In contrast to orbital cellulitis, patients with periorbital cellulitis do not have bulging of the eye (proptosis), limited eye movement (ophthalmoplegia), pain on eye movement, or loss of vision. If any of these features is present, one must assume that the patient has orbital cellulitis and begin treatment with IV antibiotics. CT scan may be done to delineate the extension of the infection.

Affected individuals may experience the following; swelling, redness, discharge, pain, shut eye, conjunctival infection, fever (mild), slightly blurred vision, teary eyes, and some reduction in vision.

Typical signs include periorbital erythema, induration, tenderness and warmth.[2]

Causes

Staphylococcus aureus, Streptococcus pneumoniae, other streptococci, and anaerobes are the most common causes, depending on the origin of the infection.[3]

The advent of the Haemophilus influenzae vaccine has dramatically decreased the incidence.[4]

Diagnosis

Full blood count (FBC), blood culture and sensitivity, imaging( X ray of the sinuses, periorbital CT scan, periorbital Ultra sound.

Treatment

Antibiotics are aimed at gram positive bacteria. Medical attention should be sought if symptoms persist beyond 2–3 days.
