高度近视是一种严重危害儿童视功能的眼病，因其对眼底造成的不可逆性改变。高度近视需要早发现、早诊断、早治疗，如不及时干预可引起近视进一步加重，甚至失明。但近视的筛查经常遇到患儿近视度数不高，进一步检查发现已有高度近视眼底改变，这种隐匿性的高度近视改变在诊疗过程中极容易被忽视。本文旨在总结近视儿童脉络膜厚度变化及其影响因素文献，为隐匿性高度近视儿童临床研究提供相关证据。

High myopia is a serious eye disease that jeopardizes the visual function of children because of the irreversible changes it caused to the fundus of the eye. High myopia needs to be detected, diagnosed and treated as early as possible, if not intervened in time, it may cause further aggravation or even blindness. However, screening for myopia often encounters the situation that children with low myopia at first who are found to have high myopia fundus changes by further examinations, and these insidious high myopia changes are easily overlooked in the diagnostic process. The study aims to summarize the literatures on choroidal thickness changes and their influencing factors in myopia children, which in order to provide relevant evidence for clinical studies in children with secretive high myopia.
