    [摘要] 睫状肌的结构和功能与许多眼科疾病的发生和发展有关，如睫状肌前旋、肥厚与青光眼相关，睫状肌收缩带动玻璃体向前运动与特发性黄斑前膜、特发性黄斑裂孔等玻璃体视网膜界面疾病相关，睫状肌功能过度和不足可导致视疲劳的发生。同时睫状肌的结构和功能也受局部因素和全身因素的影响，局部的眼外伤可导致睫状体水肿，脑外伤可导致睫状肌痉挛，心理因素也可影响睫状肌的功能状态。这些因素可通过直接作用于外周睫状肌导致其结构和功能异常，也可通过中枢的神经支配影响睫状肌的功能状态。因此，深入理解睫状肌的结构及其神经支配对于临床疾病的诊疗及相关领域的研究有很大意义。本文旨在总结睫状肌结构和功能，着重从睫状肌水平、中脑Edinger-Westphal核水平和核上水平，阐述睫状肌神经支配的概况。

    [Abstract] The structure and function of ciliary muscle are related to the occurrence and development of many ophthalmic diseases， such as anterior rotation， hypertrophy of ciliary muscle are associated with glaucoma， vitreous body movement driven by ciliary muscle contraction is related to vitreoretinal interface diseases such as idiopathic macular membrane and idiopathic macular hole ......
