Purpose: To investigate the comparison of retinal nerve fiber layer (RNFL) thickness and optic disc parameters measured by optical coherence tomography (Cirrus HD-OCT®) in dominant and non-dominant eyes. Methods: Seventy-one subjects without underlying ocular disease were recruited for the present study. Ocular dominance was determined using the hole-in-the-card test. Comprehensive standardized eye examinations were performed. Scans of the optic disc and RNFL were performed using OCT. Results: The mean intraocular pressure (IOP) of the dominant eye was higher than its counterpart (p = 0.025). No significant differences were observed in uncorrected visual acuity, refractive error and axial length between dominant and non-dominant eyes (p = 0.235, 0.180, 0.850). No RNFL and optic disc features were identified in the dominant from non-dominant eyes. Conclusions: Although dominant eyes tended to have higher IOP than non-dominant eyes, no consistent ocular structural differences between dominant and non-dominant eyes with the use of OCT were found.
