Analysis of Oscillatory Eye Movements as a Nystagmus, Manifested in the Visual System

摘要

The state of normality of the oculomotor equilibrium is determined by the characteristics of eye movements that are analyzed from the point of view of kinematic and dynamic dimensions. A great deal of research has highlighted and identified the connections between eye movements and the mode of action of stimuli in the environment. Depending on the degree of action of these stimuli, the reaction in the visual system may allow the identification of functional, neuromotor or normal physiological abnormalities. The first part of the paper analyzes the types of eye movements that the visual system can perform both monocular and binocular and the normal and abnormal physiological limits are identified. Of all these, the emphasis was placed on the oscillatory movements of the eyeball to highlight the importance of binocular balance on the stability of the formation of the corresponded retinal images. In the second part of the paper, we present the experimental system designed and built to record these continuous and/or oscillatory movements in order to compare the ideal trajectory with that performed by each ocular globe. In the final part of the paper, the results of image processing of the eyeball movements and the conclusions regarding the influence of external stimuli on oculomotor balance are presented.
