The Prevalence of Nystagmus: The Leicestershire Nystagmus Survey

Investigative Opthalmology & Visual Science, 2009
Nystagmus, which can be infantile (congenital) or acquired, affects all ages. The prevalence of nystagmus in the general population is unknown. New genetic research and therapeutic modalities are emerging. Previous estimates have been based on wider ophthalmic epidemiologic studies within specific occupational or age groups. The authors carried out the

Gravity-Dependent Modulation of Downbeat Nystagmus: Insights From Velocity-Storage Dysfunction. [PDF]

Ann Clin Transl Neurol
ABSTRACT Objective Downbeat nystagmus varies with head position, a phenomenon termed gravity‐dependent modulation. We aimed to clarify its mechanism using a velocity‐storage model. Methods In 10 patients with downbeat nystagmus due to cerebellar disorders, we recorded eye movements at different pitch‐ and roll‐axis head positions.
