Video Head Impulse Test (vHIT): Value of Gain and Refixation Saccades in Unilateral Vestibular Neuritis

, 2022
The aim of this study was to evaluate gain and refixation saccades (covert and overt) using a video head impulse test (vHIT) in the horizontal and vertical planes in patients after the onset of unilateral acute vestibular neuritis (AVN).

The Relationship of Vestibulo-Ocular Reflex With Self-Reported Dizziness Handicap in Patients With Vestibular Deafferentation

Ear, Nose & Throat Journal, 2021
The relationship between objective vestibular tests and subjective vestibular tests is a controversial topic. In this study, to contribute to this issue, the vestibulo-ocular reflex features and their relationship with balance perception at long-term ...

Dopamine and impairment at the executive level. [PDF]

, 1999
Patients with schizophrenia have an impairment in the inhibition of reflexive saccades, as a consequence of a functional impairment of the prefrontal cortex, which has not yet been encapsulated in terms of a formal model.

Head impulses in complete bilateral vestibular loss: Catch-up saccades require visual input [PDF]

, 2013
Patients with bilateral vestibular loss (BVL) experience oscillopsia during passive head movements,(1) e.g., walking or driving. Because their vestibulo-ocular reflex does not stabilize gaze with compensatory eye movements, patients with vestibular ...

Recovery Pattern of High-Frequency Acceleration Vestibulo-Ocular Reflex in Unilateral Vestibular Neuritis: A Preliminary Study

Frontiers in Neurology, 2019
Objective: To explore the recovery pattern of the high-frequency acceleration vestibulo-ocular reflex (VOR) function in unilateral vestibular neuritis (UVN).Methods: Forty-seven consecutive patients with UVN were recruited within 10 days of symptom onset

Symptoms in unilateral vestibular hypofunction are associated with number of catch-up saccades and retinal error: results from the population-based KORA FF4 study

Frontiers in Neurology, 2023
ObjectiveThe presence and intensity of symptoms vary in patients with unilateral vestibular hypofunction. We aimed to determine which saccadic and vestibulo-ocular reflex parameters best predict the presence of symptoms in unilateral vestibular ...

Functional Head Impulse Testing Might Be Useful for Assessing Vestibular Compensation After Unilateral Vestibular Loss

Frontiers in Neurology, 2018
Background: Loss of the vestibulo-ocular reflex (VOR) affects visual acuity during head movements. Previous studies have shown that compensatory eye-saccades improve visual acuity and that the timing of the saccade is important.

Inferential eye movement control while following dynamic gaze

eLife, 2023
Attending to other people’s gaze is evolutionary important to make inferences about intentions and actions. Gaze influences covert attention and triggers eye movements.

Back to basics: The effects of block vs. interleaved trial administration on pro- and anti-saccade performance. [PDF]

PLoS ONE, 2017
The pro and anti-saccade task (PAT) is a widely used tool in the study of overt and covert attention with promising potential role in neurocognitive and psychiatric assessment.
