睑缘张力改变及其相关疾病的研究进展

眼睑是重要眼附属器,构成了保护眼球的屏障,并具有散布泪液于角膜和结膜的作用.睑缘为眼睑皮肤与睑结膜交界处,其张力的改变可引起眼睑位置与功能的异常.除了可造成睑内翻、睑外翻、倒睫等常见疾病外,还与眼睑痉挛、结膜松弛症、结膜淋巴管扩张及各种原因引起的眼睑皮肤松弛有关.本文对国内外睑缘张力测量方法及与眼睑张力改变相关眼病的研究进展作一综述.

Research progress of the change of eyelid-marginal tension and its related diseases

Eyelid is one of the most important appendages of the eye,not only forming a barrier to protect the eye ball,but also spreading tears to the cornea and conjunctiva.The eyelid margin refers to the junction area between the eyelid skin and palpebral conjunctiva,the tensional change of which may lead to the blepharal abnormality related to its location and function.In addition to causing some common diseases,e.g.entropion,ectropion,trichiasis,etc,the change of eyelid marginal tension may also be associated with blepharospasm,conjunctivochalasis,conjunctival lymphangiectasia and the floppy of eyelid skin caused by a variety of pathogenesis.This paper summarizes both the native and foreign researches on the measurement methods of eyelid-marginal tension and related ophthalmopathy.
