for morbid obesity. In the subsequent 4 months, he suffered from recurrent and intense vomiting, losing 40 kg. Asymptomatic hypokalemia and hypomagnesemia were discovered and supplemented. At this time, systematic oral vitamin therapy was begun. One month later, he started to describe blurred vision and vertical oscillopsia. Neurological examination revealed ataxia and nystagmus. Standard biolo...

This study explores the effect of a program of sensory integration therapy, with emphasis on vestibular stzmulation actzvities, on the duration of postrotary nystagmus zn three learning-disabled children. The single-subject methodology employed allowed a more individualistic and longitudinal investigation of nystagmus patterns in the three subjects. The graphic and statistical analysis of the d...

Superior Semicircular Canal Syndrome (SSCS) or Dehiscence is a rare abnormality in the medical field form of balance disturbance vertigo caused by loud noises changes pressure causing rupture roof superior semicircular canal. SSCS was first described Lloyd Minor 1998 after more than 70 years since Tullio and Hennebert discovered phenomenon, condition which nystagmus triggered noises, nystagmus,...

Nystagmus refers to involuntary, typically conjugate, often rhythmic oscillations of the eyes. The most common cause of nystagmus in children is infantile nystagmus syndrome (INS). INS presents within the first few months of life and is sometimes accompanied by an ocular condition associated with sensory impairment. Because this condition affects a person throughout life, it is important to und...

We report 3 patients with acquired nystagmus who were treated with eye muscle tenotomy and reat­ tachment. The first patient had acquired pendular nystagmus (APN) associated with multiple sclerosis (MS) and underwent bilateral medial rectus tenoto­ mies and bilateral lateral rectus recessions to cor­ rect exotropia. Eye movements were recorded before surgery, after surgery, and after surgery an...

BACKGROUND AND OBJECTIVES To analyze the clinical correlation between perverted nystagmus and brain magnetic resonance imaging (MRI) abnormal findings and to evaluate whether perverted nystagmus is clinically significant results of brain abnormal lesions or not. SUBJECTS AND METHODS We performed medical charts review from January 2008 to July 2014, retrospectively. Patients who were suspected...

Saccades, including fast phases of nystagmus, disappear during drowsiness and non-rapid eye movement (NREM) sleep, but are present during the alert state and REM sleep. The purpose of this study was to determine whether spontaneous nystagmus is present in patients with vestibular neuritis during REM sleep. Eight patients with spontaneous nystagmus due to vestibular neuritis and eight control pa...

The presence of nystagmus differentiates a high cervical cord and brainstem lesion in quadriplegic patient.

The functional status of the velocity storage mechanism was studied in patients at long-term follow-up (2 to 4 years) after unilateral vestibular neurectomy. The time constant of the vestibulo-ocular reflex (VORtc), the effect of head tilt on postrotatory nystagmus, optokinetic after-nystagmus (OKAN), and nystagmus after rapid head shaking were studied in 10 patients. In agreement with previous...

Matthew J. Thurtell, MBBS Konrad P. Weber, MD G. Michael Halmagyi, MD A 40-year-old female migraineur reported intermittent unsteadiness with headache. On examination, she had gaze-evoked horizontal-torsional nystagmus that was also evident during pursuit (video). Nystagmus recordings showed increasing-velocity slow phases typical for congenital nystagmus (CN) (figure 1). A relative subsequentl...
