Rare but dangerous infection of the tissues around the eye (eyelids and cheeks). It is more common in childhood.
It usually occurs as a complication of sinusitis (or another infection) that spreads to the eye.
Symptoms include a red eye, swelling of the eyelid and fever. In more severe cases it can cause a 'bulging eye' (exophthalmos), double vision or loss of vision.
Diagnosis is made clinically by interview and physical examination. If possible, a pus culture should be taken to identify the bacteria responsible.
Treatment is with intravenous antibiotics. In more severe cases, surgery may be needed to drain the accumulated pus.
It is a medical emergency if the eye pops out of its socket or if you cannot move it, or if you experience loss of vision; go to hospital with an ophthalmologist to assess your case.
