Abstract

A dacryolith was discovered in the lacrimal sac during a dacryocystorhinostomy for chronic dacryocystitis in which there was mucocele formation. Morphological examination confirmed the presence of an eyelash at the centre of the stone and electron microscopy demonstrated the presence of fungi (Candida sp.) in a matrix which was of markedly vairable morphology. The mechanism by which a hair enters the punctum and passes along the canaliculus may be attributed to the step-like pattern of ridges on the surface of a hair. The directional nature of these ridges dictates preferential movement towards the root end of the hair and prevents movements in the opposite direction.

摘要

在为慢性泪囊炎伴黏液囊肿形成而行泪囊鼻腔吻合术时，在泪囊中发现了一个泪石。形态学检查证实在结石中心存在一根睫毛，电子显微镜显示在形态明显可变的基质中有真菌（念珠菌属）。毛发进入泪点并沿泪小管前行的机制可能归因于毛发表面的阶梯状嵴纹。这些嵴纹的方向性决定了毛发优先向根部移动，并阻止其向相反方向移动。
