We observe a patients ability to fixate throughout our usual entrance testing, especially while watching him attend to a fixation target during cover testing. These four tests can help you evaluate saccades. (The NSUCO/Maples Oculomotor Test evaluates both saccades and pursuits.)

Oct 15, 2015 · 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 ...

Thieme. 13 Diplopia. The goal of all normal eye movements is to place and maintain an object of visual interest on each fovea simultaneously to allow visualization of a single, stable object. Any deviation from normal eye movement will degrade vision and will often give the perception of double vision (diplopia).The Developmental Eye Movement (DEM) test is a commonly used number naming test to assess and quantify oculomotor skills of children in a simulated reading environment. 1,2 In contrast to earlier oculomotor assessment tools of visual-verbal format, such as the King-Devick test, 3,4 the DEM test aims to factor out the effects of rapid automaticity naming …
This study looked for correlations between different baseline assessments for concussion used for child and adolescent athletes: King-Devick (K-D) is a number-naming test assessing saccadic eye movement, ImPACT assesses working memory, visual motor speed and reaction time, while SCAT3 assesses working memory, concentration, and balance. Foot-eye coordination refers to the link between visual inputs or signals sent from the eye to the brain, and the eventual foot movements one makes in response. Foot-eye coordination can be understood as very similar to hand-eye coordinatio...Saccades are rapid eye movements designed to shift the fovea to objects of visual interest.
