Simulation of Oscillopsia in Virtual Reality [PDF]

British and Irish Orthoptic Journal, 2018
Purpose: Nystagmus is characterised by involuntary eye movement. A proportion of those with nystagmus experience the world constantly in motion as their eyes move: a symptom known as oscillopsia.

A Tool to Quantify the Functional Impact of Oscillopsia [PDF]

Frontiers in Neurology, 2018
BackgroundIndividuals with bilateral vestibular hypofunction (BVH) often report symptoms of oscillopsia during walking. Existing assessments of oscillopsia are limited to descriptions of severity and symptom frequency, neither of which provides a ...

[Oscillopsia: pathophysiological mechanisms and treatment].

Revue neurologique, 2007
Oscillopsia is an illusion of an unstable visual world. It is associated with poor visual acuity and is a disabling and stressful symptom reported by numerous patients with neurological disorders. The goal of this paper is to review the physiology of the systems subserving stable vision, the various pathophysiological mechanisms of oscillopsia and the ...

Nystagmus and oscillopsia

European Journal of Neurology, 2011
The ocular motor system consists of several subsystems, including the vestibular ocular nystagmus saccade system, the pursuit system, the fixation and gaze‐holding system and the vergence system. All these subsystems aid the stabilization of the images on the retina during eye and head movements and any kind of disturbance of one of the systems can ...

Oscillopsia unmasked: Anti-epileptic drug interaction at therapeutic doses

Indian Journal of Ophthalmology. Case Reports
Anti-epileptic drugs (AEDs) are known to be associated with visual side effects, including oscillopsia and nystagmus. We report the case of a 22-year-old male with symptomatic focal seizures and organic affective disorder, on multiple AEDs, who developed

On the Origin of Oscillopsia during Pedunculopontine Stimulation

Stereotactic and Functional Neurosurgery, 2012
We report a case of induced oscillopsia caused by deep brain stimulation (DBS) of the pedunculopontine nucleus (PPN). Recent reports have described involuntary oscillopsia during DBS of the PPN that patients have described as <i>trembling vision</i>. Here we substantiate this observation using infra-red eye tracking.

Balance Disorders in Young and Middle-Aged Adults: NHANES, 2001-2004 and 2021-2023. [PDF]

Laryngoscope
This study presents nationally‐representative estimates from two health exam surveys, NHANES 2001–2004 and 2021–2023. In the two decades between test periods, scores on the modified Romberg screening test for balance function demonstrated significantly better age‐specific performance in 2021–2023.

Mutation in RNF170 Causes Unsteady Gait with Hypertrophic Olivary Degeneration. [PDF]

Clin Case Rep
ABSTRACT Hypertrophic olivary degeneration (HOD) is a rare form of transsynaptic degeneration resulting from disruption of the Guillain–Mollaret triangle, typically presenting with palatal tremor, ataxia, and nystagmus. Mutations in the Ring Finger Protein 170 (RNF170) gene have been associated with autosomal dominant sensory ataxia.

Oculopalatal tremor: Illustrative cases with a review of literature

Annals of Movement Disorders, 2021
Oculopalatal tremor (OPT) is a unique clinical sign characterized by involuntary movements of the soft palate in synchrony with ocular nystagmus, usually the pendular type.
