SACCADIC PURSUIT Meaning and
Definition
-
Saccadic pursuit refers to a type of eye movement characterized by rapid, jerky motions known as saccades, which are employed to accurately track moving objects or targets in the visual field. It is a crucial component of the oculomotor system, responsible for maintaining gaze stability during the pursuit of moving objects.
During saccadic pursuit, the eyes move quickly in a step-like pattern, quickly fixating on the target/object of interest to minimize image blur, and then smoothly following the target as it moves. These saccadic eye movements occur involuntarily and are controlled by a combination of neural signals originating from the brainstem and visual cortex.
Saccadic pursuit aids in acquiring and maintaining visual information of a moving stimulus, allowing individuals to accurately track the trajectory and position of objects within their visual environment. Impairments in saccadic pursuit can lead to difficulties in visually tracking moving objects, affecting activities such as reading, sports, or any task that requires the maintenance of focused visual attention on a moving target.
This eye movement phenomenon is extensively studied in ophthalmology, neurophysiology, and psychology to understand visual perception, eye-brain coordination, and related visual disorders. Techniques involving eye tracking devices and video-oculography have been developed to evaluate and measure saccadic pursuit accuracy and velocity, providing valuable insights into the functioning of the visual system and potential abnormalities or impairments.

Etymology of SACCADIC PURSUIT
The term "saccadic pursuit" is composed of two words: "saccadic" and "pursuit".
1. Saccadic: The word "saccadic" is derived from the Greek word "sakkadikós", which means "jerk-like" or "to jerk". It comes from the Greek word "sakkadēs", which means "pertaining to a jerk". The term was first used in the field of ophthalmology to describe the fast, jerky movements of the eyes when shifting attention from one point to another.
2. Pursuit: The word "pursuit" originates from the Middle English word "poursuyten", which comes from the Old French word "poursivre", meaning "to follow or pursue".
