近视是指外界的平行光线经过眼的屈光系统后落在视网膜黄斑中心凹前方的屈光状态。近视严重影响了青少年的健康成长,近视防控成为社会普遍关注的热点问题。研究普遍认为,近视与脉络膜变化有着密切关系,随着屈光度增加、眼轴增长,脉络膜厚度呈现逐渐变薄趋势。循证医学研究证实有效的近视防控方法(角膜塑形镜、离焦镜片、阿托品滴眼液、光照、后巩膜加固术等)均呈现出脉络膜增厚效应,提示脉络膜增厚是近视控制的保护因素。本文围绕现行的近视防控有效方法对脉络膜厚度的影响展开综述,以期为将脉络膜厚度变化作为近视防控疗效评价指标提供参考。

[Abstract]
Myopia refers to the refraction state in front of macular fovea when the external parallel light falls through the refractive system of the eye. Myopia has seriously affected the healthy growth of teenagers,so that prevention and control of myopia have become a hot issue of social concern. Studies generally agreed that myopia has a close relationship with choroid changes, and the choroid thickness shows a gradual thinning trend with the increase of diopter and ocular axis. Evidence-based medical studies have proved that effective methods for myopia prevention and control(orthokeratology, defocus lens, atropine eye drops, illumination, posterior scleral reinforcement, etc.)showed choroid thickening effect, suggesting that choroid thickening is a protective factor for myopia control. In order to provide a reference for the change of choroid thickness as an evaluation index of myopia prevention and control efficacy, this paper reviews the effect of current effective methods of myopia prevention and control on choroid thickness.
