目的 研究不同注视距离对儿童眼球散光度数和轴位的影响.方法 横断面研究.招募25例(50眼)使用1%阿托品眼膏扩瞳验光后散光度数大于0.50 D的5~7岁儿童,足矫配镜,并应用红外线自动验光仪测量其戴镜情况下,视远(5 m)和视近(33 cm)的散光度数和轴位.采用t检验和相关分析.结果 视近时散光度数平均变化(0.35±0.82)D(t=-3.004,P<0.01),散光度数的变化程度与散光度数高低无相关性.62%(31眼)视近时散光轴位向顺规方向转动1°~57°,平均转动(17±13)°,38%(19眼)视近时散光轴位向逆规方向转动1°~52°,平均转动(15±14)°,散光轴位的变化程度与散光度数高低无相关性.结论 因儿童验光远近不同距离散光度数和轴位会改变,故给儿童配镜时,需考虑近用散光度数和轴位的变化.

Objective To study the effect of reading distances on the axis and degree of astigmatism.Methods Twenty-five children (50 eyes) with astigmatism greater than 0.50 D were investigated in a cross-sectional study.The children were between 5~7 years of age.They were given corrective glasses based on the results of optometric tests using 1% atropine.An infrared autorefractor was used to measure the axis and degree of astigmatism for far (5 m) and near (33 cm) reading distances with full-correction spectacles.A t-test and correlation analysis were used for analysis.Results Changes in the degree of astigmatism were 0.35±0.82 D (t=-3.004,P<0.01) on average for the near reading distance and the change in the extent of the degree of astigmatism showed no correlation with the degree of astigmatism.62% (31 eyes) had with-the-rule astigmatism with an axis of 1°~57° on average (17±13)° rocating for near reading distances,while 38% (19 eyes) had against-the-rule astigmatism with an axis of 1°~52° on average (15±14)°.The change in the axis of astigmatism had no correlation with the degree of astigmatism.Conclusion The degree and axis of astigmatism changes with different reading distances in children so we need to think about the change in the axis of astigmatism when prescribing glasses for children.
