title: [CT of the orbit in Graves' ophthalmopathy].
abstract: Fifty patients suffering from Graves' disease underwent CT examination of the orbit. The medical rectus width was measured, together with the degree of proptosis and the value of the preseptal area, in order to evaluate the volumetric increase in both the muscle and the fatty tissue. The three parameters were correlated with disorders of ocular motility and with optic neuropathy. The results indicate the presence of 3 classes of patients; a) with main or exclusive increase of muscular tissue; b) with main or exclusive increase of fatty tissue; c) with increase of both muscular and fatty tissues. Only in patients from class c) disorders of ocular motility and optic neuropathy were seen to occur.
