摘要
目的:研究Graves病(GD)眼眶改变的CT扫描表现,探讨CT检查在GD临床诊断和治疗中的应用价值。方法:对68例经临床和实验室检查诊断为GD患者的136只眼眶进行CT扫描检查,并对结果进行统计学分析。结果:GD患者常表现为眼外肌增粗,其眼外肌大小与正常人比较差异有统计学意义(均P<0.05),其中内直肌最常受累(67.6%),其次为下直肌(58.8%)、上直肌(45.6%),最后是外直肌(30.9%)。在136只眼眶中发现眼球突出118只眼,其中I度突眼97只眼,Ⅱ度突眼21只眼,突眼发现率86.8%(临床上突眼诊断率66.9%)。GD患者还存在眼外肌密度变化等影像学改变。结论:眼眶CT扫描可作为GD患者的常规检查方法,指导Graves眼病(GO)的诊断和治疗。
Objective： To investigate CT features of the orbit of Graves＇ disease（GD） and explore the value of CT in clinical diagnosis and treatment in patient with GD. Methods： The manifestations of CT scan in 68 cases （136 orbits） with GD were studied in respect to the size and density of the extraocular muscles, exophthalmos and other manifestations. Results： The extraocular muscles in patients with GD were significantly larger than those in normal person （all P〈0.05）. Among the enlarged extraocular muscles, medial rectus was more frequently involved（67.6%）, inferior rectus（58.8%） and superior rectus （45.6%） were the next, the last was lateral rectus（30.9%）. In all 136 eyes, there were 118 eyes with exophthalmos. Among the 118 eyes with exophthalmos, there were 97 eyes with degree Ⅰ exophthalmos and 21 eyes with degree Ⅱ exophthalmos. The detecting rate of exophthalmos was 86.8% in CT, but 66.9% in clinical diagnosis. The density change of the extraocular muscles and other characteristic manifestations were found in patients with GD. Conclusion： Orbital CT scan can become a routine examination and can be useful to clinical diagnosis and treatment in patients with Graves＇ ophthalmopathy（GO）.
