Periorbital cellulitis

September 18, 2019


Periorbital cellulitis, also known as
preseptal cellulitis, is an inflammation and infection of the eyelid and portions
of skin around the eye, anterior to the orbital septum. 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; 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 antibiotics. In contrast to
orbital cellulitis, patients with periorbital cellulitis do not have
bulging of the eye, limited eye movement, 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 injection, fever, slightly blurred vision, teary
eyes, and some reduction in vision. Typical signs include periorbital
erythema, induration, tenderness and warmth.
Causes Staphylococcus and streptococcus
bacteria are commonly implicated. The advent of the Haemophilus influenzae
vaccine has dramatically decreased the incidence.
Treatment Antibiotics are aimed at gram positive
bacteria. Warm to hot compresses help with pain and inflammation. Medical
attention should be sought if symptoms persist beyond 2–3 days.
