Abstract
A 61-year-old woman was found to be affected with a pyocele of the frontal sinus that caused an amaurosis. After having had fever, orbital pain, and large swelling just above the right eye persisting several days, the patient lost her sight. It was diagnosed that the loss of sight was caused by orbital cellulitis complicated with the pyocele of the frontal sinus. The patient was finally treated surgically by complete frontal sinusectomy, but her vision was not recovered.
From the present case and the past literature the conclusions can be drawn as follows: 1) There may, if rarely nowadays, happen a case that a pyocele of the frontal sinus induces the visual impairment.
2) Such a case may be caused by orbital cellulitis or collateral inflammatory edema coming from subperiostal abscess formation in orbita, each of which is complicated with a pyocele of the frontal sinus.
