Overview
Orbital cellulitis is a serious infection of the orbital tissues which can lead to restriction of eye movements, loss of vision and even loss of life. Orbital cellulitis is an inflammation of eye tissues posterior to the orbital septum. It most commonly refers to an acute spread of infection into the eye socket from either the adjacent sinuses or through the blood. When it affects the rear of the eye, it is known as retro-orbital cellulitis.
It should not be confused with periorbital cellulitis, which refers to cellulitis anterior to the septum.
Diagnosis
Orbital cellulitis should be differentiated from preseptal cellulitis which is confined to structures anterior to orbital septum. Where as, orbital cellulitis involves structures posterior to orbital septum which includes fat and ocular muscles.
History and Symptoms
Patients present with sudden onset of fever, proptosis, restricted eye movement, and swelling and redness of the eye lids. It is usually caused by a previous sinusitis.
Physical Examination
Eyes
MRI and CT
Treatment
Because of concern for spread of infection, patients must be admitted to the hospital to receive intravenous antibiotics. The feared complications include cavernous sinus thrombosis and meningitis. Abscess formation is another complication and may require surgical drainage.
Orbital cellulitis is considered an ophthalmological emergency.
