Statistical Study of Single Saccade Eye Movement Forms

The study is devoted to analysis of records of rapid coordinated eye movements—saccades. Saccadic eye movements are performed by a human several thousand times a day and have a standard form. Changes in the movement of the eyes, including saccades, are noted in the case of disorders of the central nervous system, middle ear organs, and after a long space flight. Eye movement testing is used in medical practice for diagnosis and control when treating disorders in functioning of the organs of the inner ear, central nervous system, and strabismus. This paper proposes a method for approximating records of saccades with possible presence of pre- and postsaccadic movements. Numerical parameters describing preand postsaccadic movements and asymmetry of a saccade are suggested. The results of a statistical study of forms of saccades in a normal person are given. The statistical study has shown that the difference in forms of saccades is significant.
