We examined 21 patients with optic neuropathy caused by paranasal sinus cysts. Their findings on rhinoscopy were classified as follows; 1) normal (2 cases), 2) inflammatory changes of the middle meatus (2 cases), 3) postoperative scar formation of the middle meatus (7 cases), 4) presence of a cyst wall (10 cases).Radiographic examination with Rhese's view showed destruction of the optic canal and/or an abnormal shadow in the paranasal sinus surrounding the optic canal in most cases.For diagnosis, careful observation of the physical findings and radiographic findings by Rhese's view are important. CT scan is also useful.In cases in which the visual disturbance progresses rapidly, probe puncture and/or probe operation is required if the clinical diagnosis has not yet been determined.
