Latent nystagmus: vestibular nystagmus with a twist.
BACKGROUND Latent nystagmus is a horizontal binocular oscillation that is evoked by unequal visual input to the 2 eyes. It develops primarily in humans with congenital esotropia. OBJECTIVE To investigate the interrelationship between latent and peripheral vestibular nystagmus and their corollary neuroanatomical pathways. METHODS Examination of subcortical neuroanatomical pathways producing ...
متن کاملPeriodic alternating nystagmus of peripheral vestibular origin.
OBJECTIVES/HYPOTHESIS Periodic alternating nystagmus (PAN) is most commonly found either in its congenital form or after cerebellar/pontomedullary lesions. However, we identified PAN in 10 patients with peripheral vestibular disorders and will try to describe their characteristics to aid in the differential diagnosis between peripheral and central etiologies. STUDY DESIGN Observation of a cas...
متن کامل[Diagnostic value of head-shaking nystagmus in vestibular clinical evaluation].
OBJECTIVES To determine the sensitivity and specificity of the head-shaking nystagmus test (HSN), the nystagmus elicited in response to a vigorous rotation of the head in the horizontal plane, in the study of patients with peripheral unilateral vestibular disease. PATIENTS AND METHODS Retrospectively, we analyze the relationships between the HSN and the rest of the videonystagmographic tests ...
متن کاملHyperventilation-induced nystagmus in a large series of vestibular patients
The Hyperventilation Test is widely used in the "bed-side examination" of vestibular patients. It can either activate a latent nystagmus in central or peripheral vestibular diseases or it can interact with a spontaneous nystagmus, by reducing it or increasing it. Aims of this study were to determine the incidence, patterns and temporal characteristics of Hyperventilation-induced nystagmus in pa...
متن کاملVestibular and optokinetic nystagmus in ketamine-anesthetized rabbits.
The aim of this work has been to analyze the modification of vestibular and optokinetic nystagmus in animals after administration of therapeutic doses of ketamine. Three healthy rabbits (two reds and one white), weighing between 2.5 and 3 kg, were submitted to electronystagmography recording. The rabbits, head blocked, were placed on a Tönnies rotatory chair in the middle of a rotatory cylindri...
