Daroff_03-9 Ocular Palatal Myoclonus

Identifier: Daroff_03-9 Title: Ocular Palatal Myoclonus Subject: Ocular Palatal Myoclonus; Oculopalatal Myoclonus; Oculopalatal Tremor Description: The relevant anatomy of this disorder involves the inferior olivary nucleus, projecting via the restiform body to the contralateral dentate nucleus, traveling to the contralateral red nucleus via the superior cerebellar peduncle, and finally back to the inferior olivary nucleus via the central tegmental tract. Lesions in the dentate nucleus or central tegmental tract cause pseudohypertrophy of the inferior olive, which is seen in all cases of ocular-palatal myoclonus. A patient with this disorder is shown. The constellation is also called “oculo-palatal tremor.” This video is part of the Daroff Collection in NOVEL, the Neuro-Ophthalmology Virtual Education Library.
