“…Therefore, it can be said that there are no statistically significant differences in retinal features for dominant and nondominant eyes. The present finding is confirmed by many works of literature 21,22,23,24 showing compatible results while Jiménez-Santos et al and Samarawickrama et al found the same finding despite they studied younger age groups (6-12 years). 23,24 However, contrary to our study findings, some studies reported a significant difference between the dominant and non-dominant eyes in the macular ganglion cell-inner plexiform layer.…”

Background: Ocular dominance is used clinically for decisions on monovision in contact lens wear and treating binocular vision anomalies.Aim: This study aimed to investigate the association between macular structure and ocular dominance in normal-sighted young adult Sudanese by using optical coherence tomography (OCT).Setting: The study was conducted at Al-Neelain eye hospital, Faculty of optometry and visual sciences, Khartoum, Sudan.Methods: A prospective, cross-sectional and comparative study was conducted in 160 eyes of 80 healthy young adults. Central macular thickness (CMT), peripapillary retinal nerve fibre layer (NFL) thickness and inner retinal layers were investigated in each subject using OCT. Hole-in-the-card was used to detect ocular dominance.Results: The findings showed that the mean value of CMT for dominant eyes was slightly thicker (224.53 ± 17.18 μm) than in non-dominant eyes (224.36 ± 16.18 μm; P = 0.947). Whereas NFL thickness for dominant eyes was thicker at 31.87 ± 10.43 μm than in non-dominant 130.83 ± 10.30 μm with P = 0.528. In general, there were no highly significant differences between dominant eyes and non-dominant eyes found in macular parameters (P 0.05).Conclusion: Central macular thickness, NFL, ganglion cell layer and retinal pigmented epithelium may have some impact on determining ocular dominance in healthy adults. We believe that the exact mechanism and effects of ocular dominance remain unclear. Thus, further evaluation is needed.Contribution: This study observed slight thicker in macular parameters for the dominant eye, particularly in CMT and NFL thickness.

“…Can it be the result of structural differences between DE and NDE? Some studies indeed found differences between the two eyes 76 – 78 but recent works did not replicate these results 79 – 82 and argued in favor of a central origin. A general hypothesis about the origin of the contralateral bias is formed below.…”

The functional consequences of the visual system lateralization referred to as “eye dominance” remain poorly understood. We previously reported shorter hand reaction times for targets appearing in the contralateral visual hemifield with respect to the dominant eye (DE). Here, we further explore this contralateral bias by studying the influence of laterally placed visual distractors on vertical saccade trajectories, a sensitive method to assess visual processing. In binocular conditions, saccade trajectory curvature was larger toward a distractor placed in the contralateral hemifield with respect to the DE (e.g., in the left visual hemifield for a participant with a right dominant eye) than toward one presented in the ipsilateral hemifield (in the right visual hemifield in our example). When two distractors were present at the same time, the vertical saccade showed curvature toward the contralateral side. In monocular conditions, when one distractor was presented, a similar larger influence of the contralateral distractor was observed only when the viewing eye was the DE. When the non dominant eye (NDE) was viewing, curvature was symmetric for both distractor sides. Interestingly, this curvature was as large as the one obtained for the contralateral distractor when the DE was viewing, suggesting that eye dominance consequences rely on inhibition mechanisms present when the DE is viewing. Overall, these results demonstrate that DE influences visual integration occurring around saccade production and support a DE-based contralateral visual bias.
