Association Between Cross-Dominance and Visual Memory - A Cross-Sectional Study

Background: Ocular dominance plays an important role in visual memory. Although many studies are done to find the relationship between cross-dominance and their performance in sports, little was known about the effect of cross-dominance in visual memory. Aim and Objective: The present study was aimed to find if there exists an association between cross-dominance and visual memory. Materials and Methods: In this study, 40 above average subjects in the age group 18–30 years of both genders with cross-dominance is taken as study group and 40 above average subjects with complete lateral dominance who are age and sex matched is taken as control. A detailed history of the subjects was collected and they are subjected to complete ophthalmological and neurological examination to rule out any neurological deficits. Dominant eye was found using miles test and visual memory was evaluated using Benton’s visual retention test. Results: In this study, it was found that though cross dominant subjects had less score than complete lateral dominant subjects, the difference is statistically insignificant. Conclusion: There is no significant difference in visual memory between the complete lateral dominance and cross dominant subjects.
