Computerized Tomography in Neuro-Ophthalmology
Soon after the original description of the first CT scanner by AMBROSE and HOUNSFIELD in 1972 the diagnostic value of CT inneuro-ophthalmology was emphasized (AMBROSE etal., 1974; CALA and MASTAGLIA, 1976; CHU etal., 1976; DAILY etal., 1976; ENZMANN etal., 1976; GAWLER etal., 1974; LAMPERT etal., 1974; SANDERS and GAWLER, 1975; TROKEL and HILAL, 1976; WRIGHT etal., 1975). After the installation of a CT scanner at Freiburg (EMI, 160x160 matrix) we started a series which put CT in the first position of diagnostic procedures after clinical, plain x-ray, and ultrasonographic (A-scan) examination when a neur-ophthalmologic question was present. Primary questions were the cause of uni-orbilateral exophthalmus, papilledema oratrophy, visual field defects, loss of vision, and disorders of ocular motility. Out of 91 patients examined, we found 43 lesions of the orbit and 45 cerebral lesions (Table1).
