Clinical Approach to Supranuclear Brainstem Saccadic Gaze Palsies

Frontiers in Neurology, 2017
Failure of brainstem supranuclear centers for saccadic eye movements results in the clinical presence of a brainstem-mediated supranuclear saccadic gaze palsy (SGP), which is manifested as slowing of saccades with or without range of motion limitation of

Saccadic eye movements in Parkinson′s disease

Indian Journal of Ophthalmology, 2014
This review focuses on saccadic eye movement research in Parkinson's disease (PD) patients. Results from various studies related to Parkinson disease and saccades have been discussed in terms of various saccadic parameters like latency, amplitude, velocity and gain.

Laminar mechanisms of saccadic suppression in primate visual cortex

Cell Reports, 2023
Summary: Saccadic eye movements are known to cause saccadic suppression, a temporary reduction in visual sensitivity and visual cortical firing rates. While saccadic suppression has been well characterized at the level of perception and single neurons ...

Managing Dystonia in Partington Syndrome

Movement Disorders Clinical Practice, EarlyView.
Abstract Background Bilateral focal hand dystonia is an almost pathognomonic sign of Partington syndrome, frequently accompanied by intellectual disability and oromotor dyspraxia. However, a few studies have focused on the treatment of this focal dystonia, making patient management uncertain.

Face recognition increases during saccade preparation. [PDF]

PLoS ONE, 2014
Face perception is integral to human perception system as it underlies social interactions. Saccadic eye movements are frequently made to bring interesting visual information, such as faces, onto the fovea for detailed processing.

Ocular Motor Abnormalities in Functional Neurological Disorder: A Video‐Oculography Study

Movement Disorders Clinical Practice, EarlyView.
Abstract Background Functional neurological disorders (FND) can include various sensory, motor or cognitive symptoms. Eye movement recordings, measured through video‐oculography, could serve as biomarkers for characterizing these dysfunctions in FND.

Convergence Deficits in Myoclonus‐Dystonia Point to Cerebellar Impairment

Movement Disorders Clinical Practice, EarlyView.
Abstract Background Myoclonus‐dystonia (M‐D) is a monogenic movement disorder, with proposed cerebellar dysfunction. Vergence eye movement deficits, characteristics of degenerative cerebellar disease, have not been studied in M‐D. Cerebellar transcranial alternating current stimulation (tACS) is considered a potential therapeutic approach.

Fixational eye movement waveforms in amblyopia: Characteristics of fast and slow eye movements

Journal of Eye Movement Research, 2019
Fixational eye movements comprise of fast microsaccades alternating with slow inter-saccadic drifts. These physiologic eye movements play an important role in visual perception.

Neural control of saccadic eye movements

Current Opinion in Neurobiology, 1993
Recent experiments report that localization of brief targets presented during an ongoing saccade is not accurate. Because interpretations of these findings challenge an important tenet of existing oculomotor models, we examine the methodological and logical bases of these conclusions.
