What is SACCADE?

SACCADE is the movement of the eyes when both eyes move quickly with tandem. This could be accompanied by the movement of the head, neck or other parts of the body. It is a brain process that allows the viewer to perceive the world around him in small, focused areas. SACCADE speed and path can be used to detect certain neurological problems.

There are four different types of sacadic movements. The visually controlled SACCADES show an eye towards a newly introduced image. The SACCADES memory shows the eye moving towards the location that is remembered, but not necessarily present. Predictive saccades are when the eyes predict the movements of the object in the field of view and follow it. Finally, anti-sacads are when the eye moves from the object sometimes in anticipation of movement that does not occur. These tests measure the threshold of the eye movement vertically and horizontally. Some conditions may be diagnosed if the speed is too fast or too slow in both directions, including pulse and overshoot dysmetry.

Saccadic movement is primarily controlled by frontal eye fields, which are areas of the brain located near the upper part of the head. The second area known as the middle eye field helps to control the movements of physical eye monitoring, especially during SACCADE. When combined, the eyes are able to move and fix quickly on areas of the surrounding environment, which allows you to create a detailed three -dimensional mental image of the area.

Human eye, during saccade, is the fastest moving part of the body, and has developed a mechanism known as a visual sacadic suppression. This eye function blocks an image that perceives the eye as a blurred achievement. This avoids nonsensical information transmitted to the brain if it could not be processed.

There are several disorders that can affect sacadic eye movement in humans. One of the more common is known as nystagmus and is characterized by slow monitoring followed by rapid Saccades afterwards. DysmetRIA underground and crossing is a disorder in which the eyes are excessively compensated or insufficiently compensated when trying to fix at a point. Glissade is a type of Saccade disorder in which the eye does not stop at a fixed point, but rather moves slowly around the point.
