Fmri and Ocular Dominance

Jan Lestak, Jaroslav Tintera, Pavel Rozsival

Abstract :

The aim of the study was to determine whether fMRI activation is dependent on ocular dominance. Our sample included 20 eyes of 10 healthy subjects (8 female with mean age 50.25 and two male with mean age 59). None of the subjects in our sample had ocular or neurological disease. All subjects were examined for sighting eye dominance (hole–in–the–hand and pointing–a–finger test) and sensory eye dominance (Worth dot test and fogging test). All the control subjects underwent functional magnetic resonance imaging examinations with stimulation of both eyes and each eye separately using a black–and–white checkerboard of size 25.8x16.2 degrees of the visual field. We observed different interocular fMRI activity in all subjects. This difference was not statistically significant (P = 0.85). Neither the directional nor sensory ocular dominance correlated with the fMRI activity. We did not even demonstrate hemispheric laterality after separate stimulation of the dominant eye.
