睫状肌作为眼部的重要组成部分，对眼的调节和房水引流有重要的调控作用。近年研究发现近视眼的睫状肌位置和形态相比正视眼或远视眼存在明显的差异，并且这种差异可能通过改变眼的调节、脉络膜张力以及眼内压等影响近视的进展。现有的证据表明较厚的睫状肌后部与近视增加存在一定的关联，但其影响近视进展的机制还未明确证实。本文即总结睫状肌差异与近视的关系及睫状肌差异影响近视变化的可能机制，为后续的研究提供参考。

As a key ocular structure, ciliary muscle has a major role in accommodating both eye and aqueous humor drainage. Recent studies have found that the position and shape of ciliary muscles in myopia are significantly different from those in emmetropia or hyperopia, and the differences of ciliary muscle may affect the progress of myopia by altering ocular accommodation, choroidal tension and intraocular pressure. The present evidence indicating that the thickening of posterior ciliary muscle was associated with the development of myopia, but the mechanism has not been clearly confirmed. This paper summarizes the relationship between the differences of ciliary muscle and myopia, and the possible mechanism of myopia changes affected by ciliary muscle, so as to provide reference for follow-up research.
