Dynamics of interhemispheric relations as a result of functional treatment in children with non-paralytic operated strabismus

Purpose. To study the dynamics of interhemispheric interactions in children with friendly strabismus as a result of functional treatment. Material and methods. The study included 135 children aged 6 to 8 (average 6.8±0.1) years with convergent non-paralytic operated strabismus in combination with hypermetropic refraction and 96 children of the same age in the control group (average 7.1±0.1 years) without ophthalmic pathology. In children with strabismus, the leading hand and dominant eye were determined before and after functional treatment. Characteristics of spatial perception were evaluated by copying of complex geometric shapes which were Taylor’s (right-handed) and Ray-Osterritz’s (left-handed). Results. After functional treatment in the group of children with non-paralytic strabismus, along with improved binocular functions and improved performance of the Taylor and Ray-Osterritz tests, there was an increase in the number of ambidextrous children and a significant decrease in the number of left-handers (p
