Correlation of orbital computed tomography and incretion in patients with thyroid associated ophthalmopathy-Ⅰ / 医学研究生学报

ABSTRACT

Objective:To evaluate the correlation of orbital computed tomography and incretion in patients with thyroid associated ophthalmopathy- Ⅰ. Methods: Seventy-six orbits of 38 patients with thyroid associated ophthalmopathy were evaluated by CT in respect to the density and the size of extraocular muscles, and 100 normal orbits of 50 healthy person were evaluated with the same indices for comparison. Results:There was significant difference in the density and the size of extraocular muscles between the patients and the healthy adults. The maximal size of extraocular muscles were positive correlation with T3,T4in TAO-Ⅰ, and negative correlation with TSH. Conclusion:The manifestation of orbital CT may be a good index in the following survey of thyroid associated ophthalmopathy-Ⅰ.
