摘　　要：目的探讨儿童视网膜检影中和状态。方法 3~14岁儿童162例(324眼),睫状肌麻痹散瞳后,分别采用点状光检影验光法和带状光检影验光法,对两种检影验光方法中和状态结果比较。结果点状光组可观察到完整的中和状态,球镜、柱镜误差可控制在±0.12D,柱镜轴位误差可控制在2°;带状光组不易观察到完整的中和状态,球镜、柱镜误差可控制在±0.25D,柱镜轴位误差可控制在5°,差异有统计学意义,P<0.05。结论点状光检影法可以最充分地观察到完美的中和像且误差范围较小,熟练掌握球镜、柱镜,更换三只镜片能达到精确中和,且散光轴位可精准到2~3度。Objective To study neutral status of children with retinoscopy.Method A total of 162（324 eyes）of children aged 3 to 14 years were selected.After ciliary muscle paralysis and mydriasis, compare the neutral state results of point photometric optometry and band photometric optometry.Result The dotted light group observed a complete neutral state,The error of sphere mirror can be controlled at ±0.12 D,The error of cylinder axis can becontrolled at 2°.It is difficult to observe the complete neutral state of the banded light group, The errors are respectively ±0.25D、 5°.P〈 0.05.Conclusion Point-like light retinoscopy is effective in observing neutral images,skilled operation can achieve accurate neutral, astigmatic axis can be accurate to 2 to 3 degrees.
