方法：争取家长同意后，选取50例7～12岁未合理矫治的近视学龄儿童为研究对象，视力<0.8，未合理矫治包括未给予规范的散瞳验光、过矫或欠矫、眼镜相关参数不合理。并给予未合理矫治儿童进行合理矫治，包括给予规范的散瞳验光； 给予消旋山莨菪碱滴眼液滴眼，每次1～2滴，每日3次； 调整眼镜在合适的范围。矫治6mo后使用综合验光仪测量正负相对调节、调节幅度、调节灵敏度。

结果：不合理矫治组矫治前后的正相对调节力、调节幅度、调节灵敏度进行统计分析，差异均有统计学意义(P<0.01)。两组的负相对调节力差异无统计学意义(P>0.01)。

结论：合理矫治能够保存更多的调节储备，进而缓解近视的进一步加深。

METHODS: After getting the parents consent, 50 school-age children(age 7～12 years old)with visual acuity <0.8 were enrolled. All the subjects existed inappropriate treatment including measuring refraction under non-cycloplegia, wearing over- or under-corrected spectacle or inappropriate spectacle parameters ect. All the subjects were treated with appropriate treatment including measuring refraction under cyclopedia, dropping raceanisodamine eye drops 1～2 drops three times per day, adjusting spectacle parameters to appropriate range, etc. Before and 6mo after appropriate treatment, eye movement parameters including positive and negative relative accommodation, amplitude of accommodation and sensitivity of accommodation were measured with the comprehensive refractometer.

RESULTS: There are statistical significance in the amplitude of accommodation, the positive relative accommodation and the sensitivity of accommodation(P<0.01)while no statistical significance in negative relative accommodation before and after appropriate treatment(P>0.01).

CONCLUSION: Appropriate treatment can save more accommodative amplitude and will benefit myopia progression.
