Graves眼病的典型CT征有:眼外肌肥大、突眼、眶内脂肪体积增加、视神经拉长、眶内脂肪脱出。眼外肌作为该病眶内主要受累组织,它的体积和形状可用CT定量和客观的测量。为了确定正常眼外肌密度的CT值和定量估计Graves病患者眼外肌的密度、体积及眼球的位置,作者临床检查了100例无眼眶和甲状腺疾患的副鼻窦疾病病人的200个正常眼眶和87例经临床和实验室检查诊断为Graves病患者的174个眼眶(均未经眶内手术和放疗),用CT评估了眼外肌的密度、体积,眼球位置和视神经复合
Typical CT signs of Graves ophthalmopathy include: extraocular muscle hypertrophy, exophthalmos, orbital fat volume increase, optic nerve elongation, orbital fat prolapse. Extraocular muscle as the main orbital lesions involved, its volume and shape can be used CT quantitative and objective measurement. In order to determine the CT value of normal extraocular muscle density and quantitatively estimate the density, volume and eyeball location of extraocular muscle in patients with Graves disease, the authors clinically examined 200 normal orbital patients with paranasal sinus disease without orbital and thyroid disorders and Of the 174 eyes diagnosed as Graves’ disease (both without orbital surgery and radiotherapy), 87 were diagnosed by clinical and laboratory tests. The density, volume, eye position and optic nerve complex
