Acquired pendular nystagmus: its characteristics, localising value and pathophysiology.
Investigations were made of 16 patients with acquired pendular nystagmus and a further 32 cases reported in the literature were reviewed. Amongst our own patients two thirds had multiple sclerosis, almost one third a cerebrovascular accident or angioma and two had optic atrophy with squint. The nystagmus took forms which could be monocular or binocular, conjugate or disconjugate and could invol...
متن کاملVertical acquired pendular nystagmus: oculomotor findings, localizing value and pathophysiology
OBJECTIVES: Evaluation of the localizing value and pathogenesis of vertical APN through examination of patients with this nystagmus form and different diagnosis. DESIGN: Three patients with vertical APN with different diseases (brainstem infarct, brainstem encephalitis and brainstem haemorrhage), but with similar topic of lesions, are presented. For registration of the nystagmus AC-electrooculo...
متن کاملLatent nystagmus and acquired pendular nystagmus masquerading as spasmus nutans.
SUMMARY We used ocular motility recordings to identify the characteristics of a rare combination of conjugate, horizontal jerk, and pendular nystagmus in a 9-year-old boy. The clinical diagnoses were amblyopia, left esotropia, congenital nystagmus, and an apparently uniocular pendular nystagmus that mimicked spasmus nutans. Ocular motility recordings revealed an unusual latent/manifest latent n...
متن کاملIs acquired pendular nystagmus always phase locked?
A patient with multiple sclerosis presented with oscillopsia due to an acquired pendular nystagmus that was dissociated in amplitude, being larger in the eye with a relative afferent pupil defect. Eye movement recordings showed an unusual dissociation in nystagmus frequency as well. Although the frequencies differed, the eyes remained phase locked as the right eye was oscillating exactly twice ...
متن کاملAcquired pendular nystagmus in multiple sclerosis and oculopalatal tremor.
OBJECTIVE Acquired pendular nystagmus occurs mainly in multiple sclerosis (MS) and focal brainstem lesions. In the later case, it is part of the syndrome of oculopalatal tremor. Even though pathophysiology of acquired pendular nystagmus has been clearly characterized experimentally in both etiologies, there is a persisting ambiguity in clinical literature, which leads one to consider both clini...
