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 کاملSpasmus nutans. A quantitative prospective study.
Spasmus nutans includes ocular oscillations, head nodding, and anomalous head positions. No quantitative longitudinal study verifying the natural history of this self-limited condition has appeared in the literature. Using infrared oculography, we prospectively examined the eye movements of otherwise neurologically normal infants in whom a diagnosis of spasmus nutans had been made. At this writ...
متن کاملSpasmus nutans and congenital ocular motor apraxia with cerebellar vermian hypoplasia.
BACKGROUND Spasmus nutans and congenital ocular motor apraxia share clinical characteristics. However, their development in a patient with cerebellar vermian hypoplasia has not been previously described. OBJECTIVE To report spasmus nutans and congenital ocular motor apraxia in a child with cerebellar vermian hypoplasia. DESIGN Case report. SETTING Tertiary-care hospital. Patient A 7-year-...
متن کاملA study of head and eye movement in spasmus nutans.
A case of spasmus nutans was studied using objective recordings of head and eye displacement in order to generate a precise description of the ocular oscillations and head nodding and to investigate their interrelationships. The ocularoscillations consisted of 11-Hz sinusoidal convergence movements. The head nodding consisted of a 3-Hz, 3 degrees peak to peak, sinusoidal oscillation in the hori...
متن کاملDiagnosing children presenting with asymmetric pendular nystagmus.
Horizontal asymmetric nystagmus usually occurs in one of three situations: secondary to an intracranial lesion, with monocular visual loss, or as part of the triad that constitutes the diagnosis of spasmus nutans (asymmetric nystagmus, abnormal head posture, head shake). Clinical records of 277 children, presenting with congenital nystagmus over an 8-year period were reviewed. Nystagmus was asy...
