[Diagnosis of optic neuropathy in endocrine orbitopathy].

By presenting the case of a patient with Graves-disease, different methods that permit detection of optic nerve compression are discussed. Beside reduced visual acuity and pathological visual fields, measurement of episcleral venous pressure, pathological visually-evoked potentials (VEP) and enlarged extraocular muscels (detected by CT and MRI) give good additional evidence of optic nerve compression in Graves-disease.
