AIM: To study the correlation between monocular mild myopic juvenile myopia degree and dominant eye.

METHODS: Totally 158 patients with juvenile monocularly mild myopia in our hospital from December 2012 to December 2013 were retrospectively analyzed, and cylindrical mirror astigmatism was used for spherical equivalent conversion. On the basis of the myopic degree, they were divided into three groups, 30 cases in group A(-0.25～-0.75D), 92 cases in B group(-1.0～-2.0D), 36 cases in group C(-2.25～-3.0D). The card hole method was selected to measure dominant eye for subjectsat nearly 33cm and 5m. After glasses correction of ametropia, the far and near dominant eyes were received measurement again.

RESULTS: The monocular mild myopia of dominant eye was compared with the non-dominant eye adjustment function, and there was no significant difference(P>0.05). The dominant eye, non-dominant eye mean diopter and other correlations of eyes in the three groups were compared, and there was no significant difference(P>0.05). The dominant eye of three groups at 5m was compared, and there was significant difference(P<0.05). The dominant eye of three groups at 33cm was compared, and there was significant difference(P<0.05). Dominant eye at different visual distance was compared, and there was significant difference(P<0.05). Monocular uncorrected eye was compared with dominant eye mild afte myopia glassesr, and there was significant difference(P< 0.05).

CONCLUSION: The formation of myopic anisometropia is related to the degree of clearly seeing objects, although glasses correction can improve the clarity and visual, but affect the choice of the dominant eye, because the myopic anisometropia appears most early in the dominant eye, therefore optician correction stage, which should be taken into consideration, and avoid the severity of the adolescent myopia.
