Analysis of Oscillatory Eye Movements
as a Nystagmus, Manifested in the Visual
System
Mihaela Ioana Baritz and Alexandra Maria Lazar
Abstract 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.
1 Introduction
Eye movement is considered an essential element in defining the normality state of
the visual system and how binocular vision is achieved and eye balance maintained.
The human visual system is characterized by a series of movements that it develops
in the form of reflexes or conscious movements, programmed and controlled by the
