儿童屈光参差与不等像视和眼轴长的关系

RELATIONSHIP BETWEEN ANISOMETROPIA, DIFFERENCE IMAGE AND OCULAR AXIS IN CHILDREN

①目的调查儿童屈光参差与不等像视和眼轴长之间的关系.②方法回顾63例屈光参差儿童的临床资料,对比分析屈光参差与不等像视、眼轴长之间的关系,并进行统计分析.③结果远视性屈光参差裸眼及矫正后不等像差之间的差异有显著性(t=2.01,P<0.05),混合性及近视性屈光参差裸眼及矫正后不等像差之间的差异均无显著性.裸眼不等像视与屈光参差无明显相关,不等像差与眼轴长之间无明显相关性.④结论必须认真考虑儿童屈光参差造成的不等像视,在用眼镜矫正治疗弱视时必须综合分析立体视、眼轴长,并将屈光参差控制在2～3 D以内.

Objective To investigate the relationship between anisometropia, difference image and ocular axis in children. Methods The clinical data of 63 children with anisometropia were reviewed. The relationship between anisometropia, difference image and ocular axis was compared and analyzed statistically. Results Significant difference existed in images before and after rectification in hyperopia anisometropia （t=2.01, P〈0.05）, but not in myopia and mixed anisometropia. There was no statistical relation either between difference image and anisometropia, or between difference image and ocular axis. Conclusion The difference image caused by anisometropia in children must be considered seriously. Stereopsis and ocular axis should be considered when amblyopia was corrected by wearing spectacles. The anisometropia should be controlled within 2-3D.
