目的分析3～12岁屈光不正患儿的散光度及散光轴向分布情况。方法对本院门诊就诊的3～12岁屈光不正患儿童进行散瞳检影验光,并对确诊为规则散光的其中散光度≥0.50D的375只散光眼的眼镜处方中的散光度数和轴位进行统计分析。结果本组3～12岁屈光不正患儿375只散光眼中复性散光306眼,占全部病例81.60%。复性散光中,复性近视散光116眼,占37.91%,复性远视散光190眼,占62.09%;单纯性散光22眼,占全部病例5.87%。其中,单纯性近视散光8眼,单纯性远视散光14眼,占单纯散光比例分别为36.36%和63.64%;混合散光47眼占12.53%。本组375规则散光眼中,循规性散光315眼,占所有病例85.2%;逆规性散光26眼,占所有病例6.93%;斜轴散光34眼,占病例9.07%。本组散光程度:0.50～1.00D者232眼,占61.87%;1.25～2.00D者92眼,占24.53%;2.25～3.00D者39眼,占10.40%;3.25D以上者12眼,占3.20%。结论3～12岁视力不良儿童375只散光眼中散光类型以复性远视散光多见,散光轴向分布以循规性散光为主。散光程度多在3.00D以下,0.50～1.00D者为最多。
Objective To analyze the astigmatism and axial distribution of astigmatism in children aged 3 ~ 12 years with refractive errors. Methods Mydriatic retinoscopy was performed on children aged 3 ~ 12 years old with refractive ametropia in our outpatient clinic. The astigmatism and axis of astigmatism in spectacles of 375 astigmatism patients whose astigmatism ≥0.50D were diagnosed as regular astigmatism Bit for statistical analysis. Results There were 306 astigmatism astigmatism in 375 astigmatism eyes of children aged 3 ~ 12 years, accounting for 81.60% of all cases. Refractive astigmatism, myopic astigmatism in 116 eyes, accounting for 37.91%, hyperopia astigmatism in 190 eyes, accounting for 62.09%; 22 cases of astigmatism, accounting for 5.87% of all cases. Among them, 8 eyes of simple myopic astigmatism and 14 eyes of simple hyperopic astigmatism, accounting for 36.36% and 63.64% respectively; 47 eyes with mixed astigmatism accounting for 12.53%. The rules of 375 rules of astigmatism eyes, regular astigmatism 315 eyes, accounting for 85.2% of all cases; 26 cases of astigmatism, accounting for 6.93% of all cases; inclined axis astigmatism 34, accounting for 9.07% cases. The degree of astigmatism in this group: 232 eyes of 0.50 ~ 1.00D, accounting for 61.87%; 92 eyes of 1.25 ~ 2.00D, accounting for 24.53%; 39 eyes of 2.25 ~ 3.00D, accounting for 10.40%; 3.25D or more 12 eyes, accounting for 3.20 %. Conclusion Astigmatism of 375 astigmatism eyes of 3 ~ 12 years old children with hyperopic astigmatism is more common. The axial distribution of astigmatism is mainly based on regular astigmatism. Degree of astigmatism more than 3.00D, 0.50 ~ 1.00D were the most.
