摘　　要：目的分析深圳市宝安区学龄前儿童屈光状态的动态变化。方法采用整群抽样方法抽取深圳市宝安区4家幼儿园的446名儿童,用伟伦Suresight手持自动验光仪进行屈光度筛查,并进行5个学期的追踪观察。结果自小班下学期至大班下学期连续5个学期的球镜度分别为(1.46±0.59)D、(1.40±0.66)D、(1.39±0.68)D、(1.39±0.70)D、(1.28±0.69)D,柱镜度分别为(-0.65±0.72)D、(-0.66±0.79)D、(-0.72±0.86)D、(-0.72±0.96)D、(-0.67±0.92)D。远视状态眼数逐学期减少,从872眼减至813眼;正视状态眼数逐学期增加,从12眼增至49眼;近视状态眼数也逐学期增加,从8眼增至30眼,差异有统计学意义(P<0.05)。结论随年龄增长,球镜度逐渐降低,柱镜度呈波浪式变化。远视眼数逐年减少,正视及近视眼数逐年增多,但散光眼数维持稳定。因此,掌握学龄前儿童的屈光状态动态变化规律,可更有针对性地开展儿童眼保健工作,早期发现及干预屈光异常。Objective To investigate dynamic changes of preschool children refractive status in Bao’an District.Methods Cluster sampling was used to recruit 446 children in 4 kindergartens in Bao’an District,Shenzhen.Refractive status was measured by Wellens Suresight hand-held autorefractor,and those kids were followed up for 5 semesters.Results Spherical Diopters in 5 continuous semesters from second term of primary class to second term of senior class were(1.46±0.59)D,(1.40±0.66)D,(1.39±0.68)D,(1.39±0.70)D,(1.28±0.69)D,while the diopters of cylindrical power were(-0.65±0.72)D,(-0.66±0.79)D,(-0.72±0.86)D,(-0.72±0.96)D,(-0.67±0.92)D.With the semester passed,the number of hyperopic eyes decreased from 872 to 813,while the number of emmetropic eyes increased from 12 to 49 and the number of myopic eyes increased from 8 to 30.The difference was statistically significant(P<0.05).Conclusion With the increase of age,spherical diopters decreased gradually,while the cylindrical diopters changed in a waving trend.The number of emmetropia and myopia increased while the number of hyperopia decreased with age,but the mumber of astigmatism remained stable.Dynamic changing patterns of preschool children’s refractive status should be discovered to develop targeted eye care program for them in order for early detection and intervention of refractive abnormality.
