Ocular dominance and balance performance in healthy adults

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.
