7例甲状腺功能障碍性视神经病变的CT显示眶尖部眼外肌中度至重度增厚，2例无神经病变的甲状腺功能障碍性眼眶病变的对照病例的白色CT显示轻微或梭形增厚。其后果包括可能的顶端压迫与视神经神经病变，无论是直接压力的神经或其血液供应。这些病例的治疗方法是口服高剂量皮质类固醇并逐渐减量，或对眶尖进行放射治疗（10天内约3，000 rad）。如果要尝试手术减压，其设计应使眶尖处的视神经脱离。
Computed assisted tomography (CT) of seven cases of dysthyroid optic neuropathy showed moderate to severe thickening of the extraocular muscles at the orbital apex, white CT of two control cases of dysthyroid orbitopathy without neuropathy showed minimal or fusiform thickening. The consequences include probable apical compression with optic nerve neuropathy either by direct pressure on the nerve or its blood supply. The management of these cases is either by oral administration of corticosteroids in high dosage with gradual tapering or radiation therapy to the orbital apex (approximately 3,000 rad over a ten-day period). If surgical decompression is to be attempted, it should be designed to decompress the optic nerve at the orbital apex.
