摘　　要：目的了解混合性散光儿童屈光发展的变化规律。方法选择门诊初诊的3～16岁儿童63例（113只眼），使用睫状肌麻痹剂检影验光后确诊为混合性散光，每年验光1次，将其连续3年的屈光结果进行追踪观察。结果3年来散光度数改变不明显（F=0．175，P=0．840），说明其最大和最小屈光子午线的屈光状态在同步发展。而远视球镜度数逐渐降低，其差异显著有统计学意义（F--14．151，P=0．000）。结论混合性散光的儿童，随年龄增长及眼球发育，屈光状态逐渐降低甚至会向近视方向发展。该类患儿如能早期戴镜矫正，可获得较满意的视力。必须强调使用睫状肌麻痹剂检影验光对儿童混合性散光的必要性和重要性。Objective To investigate changes in refractive trends error of children with mixed astigmatism, Method Sixty three patients （113 eyes） with mixed astigmatism between 3 and 16 years of age were confirmed as mixed astigmatism with cycloplegic retinoscopy. Participates were performed optometric examination annually over a 3 year period. Refractive status data were collected and trends of in refractive error changes were analyzed. Result The astigmatic values remained stable over three year period （F =0.175, P =0.840）, which indicated the maximum and minimum refractive trends errors could help the evolvement. There was a statistically highly significant difference in degrees of spherical lens that appeared to gradually decreased （F =14.151, P =0.000）. Conclusions Refractive status can evolve into myopia as growth and development of ocular optical components in children with mixed astigmatism. Early screening and cum correction is advantageous to the children with mixed astigmatism. It is also highly recommend that cycloplegic retinoscopy is a very important and necessary method for diagnosis and therapy of children with mixed astigmatism.
