Binocular vision in subjects with non-typical interhemispheric relations and with non-typical lateralization of functions (adult stutterers) have been compared with the norm. Application of dioptic and fusional procedures reveals that in stutterers non-typical interhemispheric organization of speech is accompanied by disturbances in organization of visual functions as well - particularly by asymmetric insufficiency of the reproductive processes in binocular vision. It is assumed that the observed asymmetry points to the functional insufficiency of the right hemisphere.
