·AIM:To explore the relationship of myopic children’s dominant eye,diopter,classes of eye and uncorrected visual acuity.METHODS:Totally 99 cases of children with their pupil back to normal after glasses were randomly selected after cycloplegic retinoscopy.The dominant eye was checked with hole-in-the-card test,classified and statistically analyzed.RESULTS:In 99 cases of myopic children,the right eye as the dominant eye,namely right type(R type)accounted for 66.7%(66/99),the difference was statistically significant(P=0.0001);when eye refraction was not equal,the eye of a relatively low refraction acted as the dominant eye in 42 cases(52.5%),there was no significant difference between the two types(P=0.527);when the eye refractive power was equal,the right eye as the dominant eye accounted for 68.4%,the difference was statistically significant(P= 0.0231);in 64 patients with different uncorrected visual acuity in both eyes,the eye of low visual acuity acted as the dominant eye in 34 eyes(53.1%),no significant difference between the two types(P=0.4795);in 35 cases of equal visual acuity in both eyes,right eye acted as dominant eye in 29 cases(82.9%),it was of highly statistically significant difference(χ2 = 30.2286,P<0.01).CONCLUSION:The R type dominant eye is common in the eyes of myopic children.For the relevance of dominant eye refraction,and also uncorrected visual acuity level,the difference was not statistically significant.
