Objective: The aim of the present study was to evaluate the correla-tion between eye dominance and hand preference among uni-versity students and to gather information on the dominant hemisphere.
Material and Methods: A total of 179 subjects (age between 16-24 yr., mean ± standart deviation= 19.37 ± 1.62), 110 females (61.5%) and 69 males (38.5%) volunteered for examination. The right/left hand preference was assessed according to Geschwind Scores (GS) by Edinburgh Inventory (Oldfield, 1971) and McManus tests. The right/left eye dominance was evaluated by the Gündoğan and McManus test methods.
Results: According to Edinburgh Inventory Oldfield test 164 (91.6%) subjects preferred to use their right hands, and 15 (8.4%) subjects preferred to use their left hands. In the McManus test 163 (91.1%) subjects preferred to use their right hands and 16 (8.9%) subjects preferred to use their left hands. There was good agreement be-tween the two methods (Kappa coefficient= 0.753, p= 0.000). When the dominant eye was evaluated with the Gündoğan method, the right eye was dominant in 110 (61.5%) subjects and the left eye was dominant in 69 (38.5%) subjects. According to the McManus test, the right eye was dominant in 128 (71.5%) subjects and the left eye was dominant in 51 (28.5%) subjects. Al-though the correlation between these two different methods was statistically significant (2= 12.378, p= 0.000), there was a weak agreement between them (Kappa coefficient= 0.256, p= 0.000). The preference of the right hand for throwing and the dominant eye were correlated significantly in the McManus tests (Fisher Exact p= 0.017; phi coefficient= 0.193, p= 0.01).
Conclusion: The rate of right hand preference and right eye dominance was significantly high among university students. This functional laterality may be due to the dominance of the left hemisphere.Keywords: Functional laterality; dominance, ocularTurkiye Klinikleri J Med Sci 2007, 27:155-163
