Recurrent external ophthalmoparesis during hormonal therapy after thyroid ablation. Case report

We here report the case of a patient who had undergone total thyroid ablation for Graves' disease. After the beginning of oral therapy with 1-thyroxine, she developed a left external ophthalmoparesis that remitted with the discontinuation of the drug and recurred whenever the replacement therapy (1-thyroxine or tri-iodothyronine) was reintroduced.
