A swollen eye
A 58 year old man presented with a two week history of swelling of his left eye after symptoms of an upper respiratory tract infection. His vision had not changed but on examination his left eye was erythematous and slightly proptosed. There was no chemosis. The range of eye movements was normal despite limited eye opening (fig 1).
Computed tomography is needed if the patient fails to improve or develops central signs or in the presence of deteriorating eye signs. Computed tomography gives information about the extent of the infection and the patient's anatomy. Surgery may be needed for sinus drainage or treatment of intracranial collections of pus.
