![]() The ability to make accurate saccades involves a very precise coordination between our central and peripheral visual systems. If a child cannot control these eye movements, he’ll lose his place and comprehension becomes a problem. In addition, when we reach the end of a line, our eyes must make a difficult reverse sweep back to the beginning of the next line. ![]() The eyes must move left to right along a straight line without deviating up or down to the lines above or below. During reading, accurate saccadic movements are critical. Saccades involve any shift in gaze, such as from road sign to speedometer, board to paper, and notes to computer screen. Saccades are eye jumps–the sudden, quick voluntary change in fixation from one object to another. Inadequate fixation skills must be addressed early in a treatment program before other oculomotor techniques are attempted because it is the foundation skill upon which others build. In school, comprehension suffers as our eyes involuntarily move off the print and words jumble or jump around. Without the ability to fixate, images will be blurry and confusing. This allows images entering the eye to be centered on the fovea, the part of the retina that gives us our clearest vision. Good fixation skills allow us to maintain a steady gaze without our eyes moving involuntarily off target.
