急性前頭どう炎より高度視力障害を来たした症例

Abstract

This paper reported a case of acute frontal sinusitis which had resulted in severe impairment of visual acuity. A 33-year-old male patient visited our hospital on November 18, 1980. The chief complaint was severe impairment of visual acuity which had begun eight days before the first visit. He also complained of orbital pain, proptosis, immobility and chemosis. X-ray and coronal CT demonstrated mass formation which infiltrated from the frontal sinus to the left orbita. The fundus had a fern-like pattern along the retinal artery.Suspecting orbital involvement, frontal and ethmoidal sinectomies were performed. It was revealed that almost all of the orbital periosteum was stripped off the orbital bone and there was a small perforation in the frontal bone.After operation, he was given corticosteroids, vasodilators, anticoagulants, and large doses of antibiotics. His visual acuity recovered gradually and became 0.05 forty days after operation.It was suspected that the severe sight impairment in this case resulted from both the circulatory disturbance of cilliary and retinal arteries, and the inflammation and atrophy of the optic nerve.
