Abstract: Investigation wae made from the psychophysiological point of view on thecharacteristics of steady tracking eye movement of schizophrenic patients. Therecords were presented in electro-ocurogram. The results indicated: (1)The steady tracking eye movement of the patients were mainly defor-med or lacking in sine waves, indicating that the patients had serious disturb-ances of tracking eye movement. (2)No difference was noticed in the abnormal tracking eye movement of patients having different length of time of illnessand different clinical expressions. (3)Difficulty in eye tracking indicated thatthe patients had obvious cognitive visual disturbances and certain degree ofdefect in attention. Some exploratory research was made on the mechanismof the incidence of illness. (4)Medication had centain effects on the experim-ental results but did not change the intrinsic characteristics of the illness itse-lf.
