Objectives At the conclusion of this program, participants should be able to: 1. Evaluate the child with nystagmus more efficiently. 2. Decide when neuro-imaging and electrophysiology studies of children with nystagmus are appropriate. 3. Recognize the potential neurologic problems presenting with nystagmus in infancy. Questions True or False: 1. Upbeating nystagmus in infancy is usually a sign...

A patient with suspected brain stem glioma involving the area of the left vestibular nuclei and cerebellar peduncle, developed paroxysmal alternating skew deviation and direction changing nystagmus after biopsy of the inferior cerebellar vermis resulting in destruction of the uvula. Between attacks she had right over left skew deviation with asymptomatic right beating horizontal nystagmus. Slow...

AMONGST 34,000 patients, 138 were found with congenital nystagmus, of whom at least twenty showed the form known as " latent nystagmus ". Of these, thirteen were classed as typical (Table). The nature and origin of this uncommon condition is a mystery. A curious fact was revealed in this study: all the patients with this form of nystagmus had another mysterious condition-alternating hyperphoria...

Dynamic overshoots are seen after voluntary re-fixation saccades. They are microsaccadic movements which follow primary saccades and have no delay. The purpose of this study was to examine the prevalence and metrics of the dynamic overshoots seen after involuntary saccades. Using infra-red oculography we demonstrate that dynamic overshoots are a common occurrence in physiological square-wave je...

Nystagmus is a periodic, involuntary eye condition. It is characterized by the smooth pursuit of the eye away from the target location followed by a quick saccade back to the target location. Nystagmus is also called “dancing eyes” as the eye movements appear pendular or jerky to an observer. Everyone has nystagmus. Trying to fixate on objects far in your periphery will produce nystagmus-like m...

PURPOSE The purpose of this study was to identify the clinical and ocular motility characteristics of congenital nystagmus and to establish the range of waveforms present in infancy. BACKGROUND The clinical condition of congenital nystagmus usually begins in infancy and may or may not be associated with visual sensory system abnormalities. Little is known about its specific waveforms in infan...

We observed a male newborn with bilateral nystagmus and central hypothyroidism without hypoprolactinemia due to a deletion of chromosome band Xq26.1q26.2, containing FRMD7 and IGSF1. These two loss-of function mutations are known to cause, respectively, congenital nystagmus and the ensemble of central hypothyroidism, hypoprolactinemia and testicular enlargement. These latter two features may no...

basal encephalocele is a rare craniofacial anomaly. in the present paper we report a 10-year-old boy presented with cleft palate, congenital nystagmus, and hypertelorism. during preoperative evaluation for cleft palate repair, a pulsatile mass was detected in the pharynx. magnetic resonance imaging showed sphenoethmoidal type of basal encephalocele and agenesis of corpus callosum. neurosurgical...
