Vestibular nystagmus as a result of the interactions between semicircular canals and the otolithic membrane subsystems of the vestibular system

: This paper discussed the importance of gaze fixation for professional pilot activities. It describes new methods for evaluating mono- and binocular fixation. The results of examinations of pilots with mild emmetropia and ametropia demonstrate that qualitative parameters of gaze fixation are important adequate assessment of visual abilities. Fixation parameters measured using standard methods and authors' techniques have been compared. The paper presents the values of gaze fixation that require rehabilitation procedures.
