The article deals with the possible connection between smooth eye tracking movement and symptoms of schizophrenia. The authors draw attention to the fact that the oculomotor function by many scientists is considered as a possible biomarker of the schizophrenic process, or as part of the phenotype of this disease. The temporal parameters of smooth follow-up movement of the eyes in a sample of 198 patients (93 men and 105 women) with paranoid schizophrenia and 46 patients with the risk of first psychosis of males were studied using video-histogram. In patients with the leading disorganization syndrome, a significant disturbance of smooth follow-up movements of the eye was observed at low signal velocities, which suggests a possible conjugated connection of eye tracking mechanisms and disorganization of thinking in schizophrenia. The authors approach the theoretical substantiation of the results obtained from the point of view of the theory of efferent copies.
