Abstract:
Visual functions were assessed within the context of the interhemispheric asymmetry in 178 children aged 6—8 yr. after surgical treatment of concomitant convergent strabismus. A control group consisted of 205 healthy contemporaries. Along with standard ophthalmic procedures, special tests were used to determine dominant eye, index of manual asymmetry (IMA) and capability to copy complex geometrical figures using left or right hand. The distributions of children by the IMA values appeared to be significantly different in strabismic and control groups. The IMA histogram of the control group had one peak indicating that, in most healthy children (more than 55%), the IMA values were in the range from +20 to +50 (moderate preference of right hand). In contrast, the IMA histogram of the strabismic patients had three peaks corresponding to the left-handedness (–30), ambilaterality (+10), and right-handedness (+60). The correlation between eye dominance and IMA was more significant in the strabismic patients. Despite the fact that, in the majority of patients, left and right eye were squinting alternately, most left-handed and right-handed patients revealed left and right eye dominance correspondingly. As concerned binocular functions and spatial perception, the ambidextrous patients (with –20
