Latent 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 کاملPharmacological tests of hypotheses for acquired pendular nystagmus.
Acquired pendular nystagmus (APN) occurs with multiple sclerosis (MS) and oculopalatal tremor (OPT); distinct features of the nystagmus have led to the development of separate models for their pathogenesis. APN in MS has been attributed to instability in the neural integrator, which normally ensures steady gaze. APN in OPT may result from electrotonic coupling between neurons in the hypertrophi...
متن کاملImprovement of acquired pendular nystagmus by gabapentin: case report.
Acquired Pendular Nystagmus (APN) may cause distressing visual symptoms in patients who are already suffering a severe general disease. Averbuch-Heller et al. conducted the first double-blind controlled study on treatment for APN. They showed that gabapentin substantially reduces pendular nystagmus and significantly increases visual acuity in the majority of patients. We present a patient with ...
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...
