摘要
目的探讨调节性集合与调节的比值(AC/A)对青少年近视的影响及其评估角膜塑形术治疗的效果。方法选取2021年3月至2022年3月湖北普瑞眼科医院进行验光配镜青少年126例为研究对象,基于近视情况将研究对象分为三组,依次为正视组(n=43)、早发组(n=41)和迟发组(n=42),按照不同的屈光矫正方法,将早发组和迟发组共83例近视的青少年重新分组,其中39例为角膜塑形镜组,而另外44例为框架眼镜组。比较三组研究对象AC/A值差异,并分析膜塑形镜组和框架眼镜组青少年戴镜前,戴镜后的1、3、6、12个月不同时间点AC/A值变化情况。结果与正视组相比,早发组的AC/A值较高,而迟发组的AC/A值则较低,三组比较差异有统计学意义(P<0.05)。角膜塑形镜组和框架眼镜组的性别、年龄、近视类型、屈光度等一般资料比较,差异无统计学意义(P>0.05)。戴镜前,角膜塑形镜组和框架眼镜组的AC/A值比较,差异无统计学意义(P>0.05);戴镜后的1、3、6、12个月,角膜塑形镜组的AC/A值低于框架眼镜组,差异有统计学意义(P<0.05)。结论在青少年近视的预防和矫正过程中,AC/A值具有重要的指导意义,并且角膜塑形术对AC/A值的调节效果显著。
Objective To explore the effect of the ratio of Accommodation Convergence/Accommodation(AC/A)on adolescent myopia and to evaluate the effectiveness of orthokeratology.Methods A total of 126 adolescents who underwent optometry and spectacle assemblage at Hubei Bright Eye Hospital from March 2021 to March 2022 were selected as the study subjects.Based on their myopia status,the subjects were divided into three groups:the emmetropia group(n=43),the early-onset myopia group(n=41),and the late-onset myopia group(n=42).A total of 83 myopic adolescents in the early-onset and late-onset groups were regrouped,39 of them into the orthokeratology group and 44 into the frame glasses group.The differences in AC/A values among subjects in the emmetropia group,early-onset myopia group,and late-onset myopia group were observed and compared,and the changes in AC/A values at different time points before wearing glasses and after 1,3,6 and 12 months of wearing glasses in the orthokeratology lens group and frame glasses group were analyzed.Results The AC/A values of the early-onset myopia group were higher than those of the emmetropia group,while the AC/A values of the late-onset myopia group were lower than those of the emmetropia group,with statistically significant differences(P<0.05).There were no statistically significant differences in general information such as gender,age,type of myopia,and refractive index between the orthokeratology lens group and the frame glasses group(P>0.05).Before wearing glasses,there were no statistically significant differences in AC/A values between the orthokeratology lens group and the frame glasses group(P>0.05).After 1,3,6 and 12 months of wearing glasses,the AC/A values of the orthokeratology lens group were lower than those of the frame glasses group,with statistically significant differences(P<0.05).Conclusion The AC/A value plays an important guiding role in the prevention and correction of myopia in adolescents,and orthokeratology has a significant accommodation effect on the AC/A values.
