Comparison of OCT Parameters between the Dominant and Nondominant Eye

Purpose: To evaluate the anatomical difference between the dominant and nondominant eyes in healthy, young adults by measuring macular, peripapillary retinal nerve fiber layer (PRNFL), and macular ganglion cell layer (MGCL) thicknesses. Methods: Two hundred healthy adults were recruited and assessed for ocular dominance using ‘a hole in the card test’. PRNFL, macular and MGCL thicknesses of both eyes were measured using spectral domain optical coherence tomography (OCT). Results: There were no statistically significant differences for average thicknesses of MGCL in each of the six areas between the dominant and nondominant eyes. No difference was observed between temporal, inferior, average PRNFL thickness and macular thickness in dominant and nondominant eyes. Conclusions: There was no intraocular anatomical difference between the dominant and nondominant eyes in healthy, young adults. J Korean Ophthalmol Soc 2014;55(11):1687-1692
