Adie's syndrome is usually a disease of unknown origin. We report two cases secondary to Sjögren syndrome.A 26-year-old man developed in few months a sensitive neuropathy with a bilateral tonic pupil. A 50-year-old woman complained of sensitive signs probably related to a ganglionopathy and dysautonomic disorders affecting sudomotor and vasomotor functions. Adie syndrome had been diagnosed three years earlier. In both patients, the systemic signs and the results of the complementary tests led to the diagnosis of Sjögren's syndrome. Corticosteroids had limited effects on the sensitive signs and no influence on the tonic pupils.Adie syndrome, isolated or accompanied by other dysautonomic disorders, may reveal or precede the diagnosis of Sjögren's syndrome.
