作为眼表系统的一个重要组成部分,泪腺及其分泌的泪液在维持眼表正常生理功能中的作用过去一直没有得到足够重视。越来越多的证据显示,泪腺在眼表的生理、病理过程中均发挥非常重要的作用,泪腺功能的异常参与干眼的发生和发展过程。作者研究团队近年来首次对泪腺解剖和功能进行了系统的基础研究,首次发现了泪腺导管上皮也具有分泌和再吸收能力,而且不同节段泪腺导管的功能有区别。我们在本文中试图从泪腺基本的解剖学、组织学、生理学和病理学角度阐述泪腺的功能以及其与干眼的关系,认为泪腺和泪腺导管的功能在干眼的发生和发展中具有重要影响,针对泪腺导管离子转运蛋白开发能够增加泪腺分泌的药物或方法对干眼的治疗有广阔的前景。
The lacrimal gland, as an essential component of the ocular surface system, along with its product, the tears, had not received sufficient attention in the past years.However, increasing evidence suggest that the lacrimal gland plays a critical role in maintaining the normal function of the eyes, and disruption of its function may lead to dry eye.In this review, the author tried to summarize the recent developments in lacrimal gland research and its role in the etiology and development of dry eye, particularly with our own research findings from lacrimal gland ducts.The author believes that more efforts should be directed to the lacrimal gland research, especially the ion transporters/channels in the lacrimal gland duct system, which may be used as targets in developing novel treatments for dry eye.
