Oculopalatal tremor (OPT) (also known as oculopalatal myoclonus or pharyngo-laryngo-diaphragmatic myoclonus) is an acquired syndrome of continuous and rhythmical movements of the soft palate combined with pendular nystagmus.  It occurs after injury to the brainstem or cerebellar regions. The concurrent nystagmus can be synchronous or asynchronous, and it may be seen as a convergent or pendular vertical nystagmus, or as a combination of both. When the palatal movements are seen in isolation, without an ocular component, this is simply known as palatal myoclonus.

The most common precipitating cause of OPT is a cerebrovascular accident of the posterior circulation disrupting the dentato-rubro-thalamic tract.
