Permanent bruxism as a manifestation of the oculo-facial syndrome related to systemic Whipple's disease.

We report here a new case of oculomasticatory syndrome related to systemic Whipple's disease. The patient presented typical ophthalmoparesis associated with ocular myorhythmia consisting of 1 Hz convergent oscillations of both eyes. The masticatory involvement was remarkable and consisted of a permanent bruxism leading to severe tooth abrasions. Possible pathophysiology of such a disorder is discussed.
