Purpose:
To check the behavior of the visual manual localization (v.m.l.) in the horizontal plane which can represent the state of the cortical connections between visual occipital centers and motor centers for the hand movement.
Material And Methods:
The examinations were performed using the manual localizer. The authors examined 14 patients with vertical deviations of the eyes caused by hyperfunction of the oblique inferior muscles and rectus inferior muscle in the left eye. V.m.l. examined both without the test and with the provoking test were in the range of the physiological norm which excludes the organic changes in the central nervous system.
Results:
The authors suggest that the reason of the vertical deviations of the eyes is not localized in the higher parts of the nervous system but probably depends on unequal development of the connections in the nuclei of the oculomotor nerves.
