Abstract 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).
