When we are looking, an eye performs continuous movements even if our eyes are fixed upon a static object. Eye micromovements are closely connected with the visual perception and reflect the motor tracking quality of the visual process. Potentials of the practical use of information relating the eye movements in case of fixation were studied with the aid of microperimeter MP-1 (Nidek Technologies) in patients with different pathologies of the visual system. Parameter uniqueness of eye micromovements has been discussed, as well as its necessity in the integrated assessment and monitoring of the functional condition in case of progressive myopia, amblyopia and central vision pathologies. In amblyopia irrespective of its genesis, eye movement data in fixation clarify the contribution of the oculomotor system into the visual acuity restriction and serve as a tool for an objective monitoring of the fixation point position and quality of eye micromovements. In case of the central vision pathology, the eccentric position parameters of the fixation area, together with the characteristics of eye micromovements, enable the assessment of the visual system potentials and adequate functional rehabilitation programme selection. In case of the progressive myopia there have been revealed several stable eye pattern movements which did not depend upon the state of the accommodative system, and there was also observed the difference in movements of the right and left eye in case of fixation, which could be used when selecting the prophylactic programme. The article discusses the field of the practical use of information relating the eye micromovements and restrictions in implementing the given method.

Key words: eye movements in case of fixation, microsaccades, myopia, amblyopia, peripheral vision.
