The diagnostic value of saccades in movement disorder patients: a practical guide and review

Abstract: Saccades are rapid eye movements designed to shift the fovea to objects of visual interest. Abnormalities of saccades offer important clues in the diagnosis of a number of movement disorders. In this review, we explore the anatomy of horizontal and vertical saccades, discuss practical aspects of their examination, and review how saccadic abnormalities in hyperkinetic and hypokinetic movement disorders aid in diagnosis, with video demonstration of classic examples. Documentation of the ease of saccade initiatio… Show more

“…Eye movements, specifically saccades, form the basis for visual exploration as they rapidly shift the fovea of the eye between areas of interest within the environment (Stuart et al, 2014a, Otero-Millan et al, 2008. Saccadic measurement has become prominent in many research fields, as deficient saccadic function can be used to understand cognitive (Hutton, 2008) or visual (Ibbotson and Krekelberg, 2011) processes, and help with neurological examination/diagnosis (Termsarasab et al, 2015) or to understand functional deficits in everyday tasks (e.g. walking) (Stuart et al, 2017a, Stuart et al, 2018.…”

“…In the fields of psychology and psychiatry, eye-tracking technology has recently been confirmed to be useful in diagnosing various diseases, including Parkinson's disease (25), Huntington's (26), abnormal gaze (27), nervous system degenerative diseases (28) and early Alzheimer's disease (29). Home eye-tracking systems can be used to follow up patients with vertigo (30).…”

“…These include early and marked saccadic slowing, initial hyperreflexia that is followed by hyporeflexia, Parkinson rigidity and myoclonus or fasciculation like movements [102,103]. With the slowing of saccadic jumps for horizontal gaze being the noticeable oculomotor abnormality (Table 1) [104][105][106]. This is attributed to the early, and sometimes rapid degeneration of the pontine brainstem.…”
