Comparison dominant eye and anisometropia by Worth 4 dot test and hole-in-the-card test

Abstract

ATM: To investigate the relationship between the oculus dominans and the eye with higher diopter among myopes, and to study the difference between the Worth 4 dot test and hole-in-the-card test. METHODS: Totally 125 cases were divided into two groups as physiogenic anisometropic group and pathological anisomitropic group according to the degree of binoculus anisometropy. Worth 4 dot test and hole-in-the-card test were used to distinguish oculus dominans respectively based on medical optometry.RESULTS: In physiogenic anisometropic group, the oculus dominans and the eye with higher diopter among myopes had significant relationship by hole-in-the-card test(Z = -4.057, PZ=-3.558, PP>0.05); distinguish the oculus dominans had no statistically significant difference between the Worth 4 dot test and hole-in-the-card test(n=125, P>0.05). CONCLUSION:The oculus dominans is determined by gene or formed during juvenile period, then myopia anisometropic may affect the choice of that. The Worth 4 dot test has some reference significance for observing oculus dominans.
