Spasmus 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 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 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 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 کاملPlant community associations of two invasive thistles
In order to combat the growing problems associated with biological invasions, many researchers have focused on identifying which communities are most vulnerable to invasion by exotic species. However, once established, invasive species can significantly change the composition of the communities that they invade. The first step to disentangling the direction of causality is to discern whether a ...
