"WebbWhat causes saccadic eye movements and why? Saccadic intrusions and oscillations: These saccades can occur when patients fixate in their eye primary position or may be superimposed during smooth chase. Square wave jerks and macrosaccadic oscillations are examples. What are saccades or pursuits, then? This is what we call a pursuit. " - Slow saccades causes

WebbPursuits occur when we are tracking a moving object, such as a ball, a car, or something on TV. Those who make inaccurate pursuits have trouble with catching balls, are often clumsy, and may seem “lost” when walking or running. Poor Fixation skills, or the ability to look at an object, is often one of the underlying causes of pursuit deficits. Webb17 jan. 2024 · Search worldwide, life-sciences literature Search.
