SACCADE Meaning and Definition

  1. A saccade is a term used in ophthalmology and neurology to describe a rapid, involuntary movement of the eye. Specifically, it refers to the quick shifting of the eye's gaze from one point to another. These movements are essential for visual perception as they enable the eyes to focus on different objects and areas of interest in the visual field.

    Saccades are characterized by their high velocity and abrupt nature. They typically occur within milliseconds and are not under conscious control. Instead, they are controlled by the brain's oculomotor system, which coordinates the movement of the eye muscles. Saccadic eye movements are believed to be a result of the brain selecting specific targets for visual processing.

    During a saccade, the eye itself does not process visual information in detail. Instead, it briefly suspends visual perception, leading to a slight period of blindness known as saccadic masking. This phenomenon ensures that the brain does not perceive a blurry or jumpy visual scene during rapid eye movements.

    Saccades can be measured and studied through eye-tracking technology, which allows researchers and healthcare professionals to better understand visual perception, attention, and cognitive processes. Studying saccades can provide insights into various neurological conditions, such as nystagmus, strabismus, and certain types of brain injuries.

  2. A sudden check or jerk with the bridle.

Etymology of SACCADE

The word "saccade" originates from the French word "saccader", which means "to jerk or snatch". The French term is derived from the Old French word "saccade" or "sacade", which originally referred to the act of tugging or yanking forcefully. The etymology can be traced back to the Late Latin term "saccare", meaning "to pull or tug". Ultimately, it is believed to have come from the Latin word "saccus", which means "bag" or "sack". The concept of rapid eye movements akin to jerky motions led to the adoption of the term "saccade" in the field of ophthalmology and vision research.
