Hashimoto's ophthalmopathy.
The authors reported 2 cases of Hashimoto's ophthalmopathy. These cases presented with no preceding illness; euthyroid state; acute presentation of painful or painless ophthalmoplegia, preferentially affecting the lateral rectus muscles; positive antithyroglobulin/antithyroid peroxidase antibodies and good responses to steroid treatment. Awareness of this atypical form of ophthalmopathy is important, as glucocorticoid treatment results in a significant improvement of this disorder.
