6~12岁近视患儿屈光度和角膜屈光力的相关性

Correlation between diopter and corneal refractive power in children with myopia aged 6~12

目的探讨6~12岁近视患儿屈光度和角膜屈光力的相关性。方法选取2016年8月~2019年2月在医院体检的6~12岁儿童150例,对所有儿童进行视力、屈光度、角膜屈光力检查与相关性分析。结果在150例儿童中,检出近视30例,检出率为20.0%。近视组的玻璃体腔深度低于非近视组,而眼轴长度高于非近视组,差异有统计学意义(P<0.05)。近视组的屈光度和角膜屈光力均显著少于非近视组,差异有统计学意义(P<0.05)。Pearson分析显示近视与屈光度、角膜屈光力、眼轴长度、玻璃体腔深度都存在相关性(P<0.05)。结论6~12岁儿童中近视比较常见,与儿童的屈光度、角膜屈光力显著相关,可影响患儿近视的发展。

Objective To explore the correlation between diopter and corneal refractive power in children with myopia aged 6~12.Methods From August 2016 to February 2019,150 cases of children aged 6~12 who chose to undergo medical examinations in our hospital were examined for visual acuity,diopter,corneal refractive power,and were given correlation analysis.Results There were 30 cases of myopia were detected in the 150 cases of children,and the detection rates were 20.0%.The vitreous cavity depth of the myopia group were lower than that of the non-myopia group,and the axial length were longer than that of the non-myopia group,the differences were statistically significant(P<0.05).The diopter and corneal power of the myopia group were significantly lower than those of the non-myopia group(P<0.05).Pearson analysis showed that myopia were related to diopter,corneal power,axial length,and vitreous cavity depth(P<0.05).Conclusion Myopia are more common in children 6~12 years of age,and are significantly related to children's diopter and corneal power,which can affect the development of myopia in children.
