Two cases of Hashimoto's thyroiditis with pupillary disturbances.

Two cases of Hashimoto's thyroiditis with pupillary disturbances are reported. Case 1 was a 58-year-old housewife, displaying pandysautonomia. Case 2 was a 65-year-old housewife, suffering from chronic polyneuropathy and polymyopathy. Both patients showed similar pupillary disturbances, suggesting both sympathetic and parasympathetic postganglionic denervation of the pupil. Hashimoto's thyroiditis may have caused the pupillary disturbances in association with generalized polyneuropathy or pandysautonomia.
