Bilateral Tonic Pupils as the Initial Manifestation of Sjogren's Syndrome

Adie's pupil is characterised by pupil dilatation, segmental iris palsy, light-near dissociation, and slow re-dilatation. Most commonly, tonic pupils are unilateral and idiopathic, but can be caused by orbital disorders and autonomic neuropathies. There are only a few case reports of tonic pupils in patients with Sjogren's syndrome, caused by an autoimmune ciliary ganglionitis. The authors report on two cases with bilateral tonic pupils as the initial manifestation of primary Sjogren's syndrome. Both patients presented with blurred vision, bilateral tonic pupils, and sicca symptoms. The findings suggest that Sjogren's syndrome should be considered in patients presenting with bilateral Adie's tonic pupils.
