Unilateral eyelid retraction secondary to contralateral ptosis in dysthyroid ophthalmopathy

A patient with dysthyroid eye disease presented with unilateral lid retraction secondary to a contralateral ptosis. While others have reported similar findings in various underlying disease processes, to the best of our knowledge this is the first case in the literature with dysthyroid ophthalmopathy, and the first where the results of surgical management are presented. The importance of testing for secondary lid retraction by manual elevation of the ptotic partner is stressed.
