Tonic pupil and sarcoidosis.
Department of Ophthalmology, Medical University of South Carolina, Charleston, South Carolina, USA
PURPOSE: To present a case of tonic pupil associated with enhancement in the region of the ciliary ganglion on magnetic resonance imaging in a patient with sarcoidosis. DESIGN: Observational case report. METHODS: A 52-year-old woman with sarcoidosis had a right pupil exhibiting sectoral palsy to light and light-near dissociation. RESULTS: Topical administration of 0.1% pilocarpine demonstrated supersensitivity of the right pupillary sphincter muscle. Magnetic resonance imaging (MRI) with contrast revealed enhancement in the region of the right ciliary ganglion. CONCLUSIONS: Tonic pupil may be a manifestation of sarcoidosis, and in such cases, MRI may show enhancement at the level of the ciliary ganglion. Sarcoidosis should be included in the differential diagnosis of tonic pupil. Copyright 2003 by Elsevier Science Inc.
