A 7-year-old girl presented at a university hospital with ptosis of the left eye. This resolved sponta- neously within 4 weeks but then the right eye became similarly affected but responded to prostigmine. Left hypertropia with restriction of the right inferior rectus, mild exophthalmos, non-tender diffuse enlargement of the thyroid, normal thyroid function tests, anti-thyroglobulin, and anti-microsomal antibodies indicated an association of autoimmune thyroiditis and ocular myasthenia. The ptosis was remedied with pyridostigmine and short-course oral prednisolone, but the hypertropia persisted.
