[Palpebral asymmetry and Graves' ophthalmopathy]

The authors report one case of Graves' ophthalmopathy with a palpebral asymmetry, which was characterized by a left ptosis and a right palpebral retraction. In connection with Graves' disease, many ocular signs were described, including exophthalmos, ophthalmoplegia, palpebral retraction and visual loss, but unilateral ptosis was rarely reported. The orbital CT-scanning demonstrated the bilateral enlargement of the extraocular muscles, due to the infiltrative process met in Graves' disease. The ptosis and the palpebral retraction were suspected to be related to the extension of this infiltrative process in the levator palpebrae.
