Purpose:
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.
