Objective To assess the effect of dominant and non-dominant vision in controlling posture in quiet stance. Method Twenty-five healthy elderly subjects agedover 60 years old and twenty-five young subjects aged under 30 years old were assessed by computerized dynamic posturography. Postural stability was measured in two conditions; dominant eye open andnon-dominant eye open. We used the sensory organization test (SOT) for evaluating sensory impairment. A SOT assessed the subject’s ability to use and integrate somatosensory input, vision, andvestibular cues effectively to maintain balance. The SOT was conducted 3 times, and the average value of the 3 trials was used for data analysis. Equilibrium scores reflected the subject’s anteroposteriorsway. The highest possible score was 100, which indicated that the subject did not sway at all, and a score of 0 indicated a fall from the footplate. Determination of ocular dominance was performed bya hole-in-the card test. Results For the twenty-five young subjects in this study, equilibrium score in two conditions did not differ. However, for elderly subjects over 60 years, the equilibriumscore in dominant vision was higher than in nondominant vision (p0.05).
