To evaluate the muscle changes of unilateral upper eyelid retraction (UER) in patients with dysthyroid ophthalmopathy (DO).
Seventy five patients with unilateral UER of DO. Male 19 patients, female 56 patients, average age 40.3±14.0 (11-71) years old. The enlargements of levator and superior rectus muscles (L-S complex) were examined using coronal and sagittal sections of orbital MRI.
No enlargement of L-S complex 29eyes (38.7%)Enlargement of L-S complex 13eyes (17.3%)Levator muscle enlargement only 28eyes (37.3%)Superior rectus muscle enlargement only 5eyes (6.7%)
High frequency of levator muscle enlargement was obtained in patients with unilateral UER. On the other hand, no changes of L-S complex were considered to be caused by Muller muscle. But it is difficult to explain the mechanism of unilateral appearance in case of no enlargement of L-S complex.
