青少年单眼轻度近视程度与主导眼间的相关性研究

Study on the correlation between monocular mild myopic juvenile myopia degree and dominant eye

目的:研究青少年单眼轻度近视主导眼与近视程度间的关系。方法:回顾分析我院2012-12/2013-12于我科门诊检查的158例青少年单眼轻度近视患者资料,以柱镜散光值作等效球镜转换,依据近视程度将其分为三组,A组30例(-0.25^-0.75D),B组92例(-1.0^-2.0D),C组36例(-2.25^-3.0D)。选择卡洞法对受检者注视近33cm处、远5m处主导眼进行测量,对屈光不正予以配镜矫正后,再对远、近处主导眼别进行重新测量。结果:单眼轻度近视主导眼、非主导眼的调节功能相较,差异无统计学意义(P>0.05)。三组主导眼、非主导眼平均屈光度与眼别的相关性相较,差异无统计学意义(P>0.05)。三组5m处主导眼眼别相较,差异有统计学意义(P<0.05)。三组33cm处主导眼眼别相较,差异有统计学意义(P<0.05)。不同视物距离下主导眼眼别相较,差异有统计学意义(P<0.05)。单眼轻度近视裸眼与配镜后主导眼眼别相较,差异有统计学意义(P<0.05)。结论:近视性屈光参差的形成,与视物的清晰程度有关,予以配镜矫治虽然可改善视物的清晰程度,同时也会影响主导眼的选择,由于近视性屈光参差最早出现于主导眼,因此配镜矫治阶段需将其考虑在内,避免青少年近视程度加重。

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.
