Ocular dominance and balance performance in healthy adults.
OBJECTIVE
To evaluate the effect of ocular dominance on balance performance in healthy adult subjects.


METHODS
Ocular dominance was determined in 24 healthy subjects using the hole-in-the-paper test. Balance function was evaluated by computerized dynamic platform posturography (CDPP). Sway index (SI), antero-posterior sway (APS) and lateral sway (LS) were served as outcome parameters.


RESULTS
The outcome parameters did not differ significantly between dominant and non-dominant eye fixation both in static and angular balance tests (SI-5.47+/-0.42, 6.23+/-0.52, p=0.146 and 18.4+/-1.07, 19.11+/-1.15, p=0.142, respectively; APS--2.26+/-4.68, -5.1+/-4.6, p=0.082 and -1.94+/-3.33, -3.64+/-2.6, p=0.48, respectively; LS--1.21+/-1.46, -1.12+/-1.66 p=0.94 and -1.98+/-1.16, -1.55+/-1.39, p=0.69, respectively).


CONCLUSIONS
Ocular dominance does not seem to affect postural function in the monovision and far viewing condition.
