orbital cellulitis

cellulitis, orbital 

Infection of the orbital contents caused by Staphylococcus aureus, Streptococcus or Haemophilus influenzae. It is often caused by the spread of infection from adjacent structures, especially the sinuses. The clinical signs are fever, pain, proptosis, redness, swelling of the lid and orbital tissue and restricted eye movements which may occasionally lead to diplopia and, as the condition worsens, visual acuity decreases. Initial management consists of parenteral antibiotics but surgery may become necessary. See lamina papyracea.
