主视眼、双眼眼压在单纯性近视早期的作用研究

The impact of dominant eye and bilateral intraocular pressure on the early stage of simple myopia

目的研究在单纯性近视早期,主视眼、双眼眼压与双眼近视程度的关系,进而探讨主视眼、眼压在单纯性近视的发生以及发展早期中可能的作用。方法对双眼屈参差小于1.5D的低度近视儿童进行了双眼Goldman压平式眼压检查、睫状肌麻痹后双眼的电脑验光以及眼轴A超检查,主视眼则采用简化的hole-in-the-card方法进行确定,然后对主视眼、双眼眼压与双眼近视程度的关系进行相关分析;结果共对133名7～13岁的单纯性近视儿童进行测量,平均年龄(10.96±1.55)岁,平均等效球镜(1.73±0.70)D,双眼平均屈光参差(0.22±0.21)D。主视眼的眼压(14.9±2.5)mmHg与非主视眼(15.0±2.5)mmHg无统计学差别(p=0.47),主视眼的等效球镜(-1.73±0.71)D与非主视眼(-1.75±0.72)D也无有意义的相关关系(r=0.03,p=0.772)。结论对于没有明显屈光参差的低度单纯性近视,主视眼、双眼眼压与双眼近视的严重程度无统计学的关系,提示在单纯性近视的发生以及发展早期,主视眼、眼压均不起明显作用。

Purpose To study the relationship among the dominant eye. bilateral intraocular pressure flOP）and the inter-eye myopic difference,and explore their probable effect in the occurrence and the early developmental stage of the mild simple myopia. Objects and Method In the mild myopic children with anisometropia which is less than 1.5D,we examine the intraocular pressure with Goldman tonometer,autorefraction after mydrisis,ocular length with A-scan ultrasonographyand determine the dominant eye with the simplified Hole-in-the Card method,then analyze their correlation. Results We examine 133 simple myopic children aged from 7 to 13 overall,whose mean age is （10.96 ± 1.55）, and mean spherical equivalent（MSE） is （1.73 ± 0. 70）D, anisometropia is 0.22D ± 0.21D.IOP of dominant and non-dominant eye is （14.9 ± 2.5）mmHgand （15.0 ± 2.5）mmHg（p=0.47）, respectively.And MSE of dominant and non-dominant eye is （-1.73 ± 0.71）Dand （-1.75 ± 0.72）D （p=0.43）,respectively.There is no significant correlation between IOP and myopia in dominant and non-dominant eye （r=0.03, p=0.772）. Conclusion In mild simple myopia without obvious anisometropia,there are no significant correlation among dominant eye. bilateral intraocular pressure and the inter-eye myopic difference,which indicates that the effect of dominant eye and IOP are not obvious during the occurrence and early stage of simple myopia.
