AN ASSESSMENT OF OCULAR DOMINANCE: A TERTIARY LEVEL HEALTH CARE CENTRE OBSERVATIONAL STUDY

Abstract

Background: Ocular Dominance was first described by Rosenbach. Ocular Dominance is the tendency to physiological preference of one eye over another eye. However, the role of Ocular Dominance in processing of visual memory and analytic tasks is unknown. Research has showed significant effects of Ocular Dominance on visual perception, motor control, color vision and sports performance. The aim of present study was to determine Ocular Dominance by the Gundogan Method which is Near Far Alignment Test. Method:This study attempts to assess Ocular Dominance and the relationship between Ocular Dominance, Gender and cerebral laterality. It is a cross sectional, comparative and analytic type of study which is carried out on 170 healthy young adults with normal visual acuity. Among them 101 subjects were male and 69 subjects were female. Detection of Ocular Dominance was done by Gundogan Test. Result: Ocular Dominance was present in human beings. Ocular Dominance was most commonly present in Right Eye. Right Eye was dominant in (118) 69.4 % subjects and Left Eye was dominant in (52)30.6 % subjects. Gender based distribution of Right eye dominancy was 70.3%(n=71) for males and 68.1%(n=47) for females. Gender distribution For Left eye dominancy, was 29.7%(n=30) for males and 31.8%(n=22) for females (p value = 0.89). Conclusion: Ocular Dominance markedly observed in human beings, and Right eye dominancy is more preponderant than Left eye. It was also concluded that gender is not a major factor to affect eye dominancy. We insinuate that Gundogen Performance Test was appear to be a more practical and fluently applicable performance Test.
