泪囊粘液囊肿是一种比较少见的泪道疾病,多发生于慢性泪囊炎或鼻泪管阻塞患者,由于泪囊粘膜萎缩及总泪小管的炎症性变化,导致总泪小管通入泪囊处闭锁,囊腔内容物无法排出,随着分泌物的积聚增多,泪囊逐漸扩张膨大,形成一充滿粘滞性分泌物的闭锁性腔隙——泪囊粘液囊肿。本病应区别于泪囊膨大,后者虽有泪囊扩张,但末形成闭锁性腔隙,囊腔内容物仍可经泪小管或鼻泪管排出。
Dacryocyst mucinous cyst is a relatively rare lacrimal duct disease, occurred in patients with chronic dacryocystitis or nasolacrimal duct obstruction, due to dacryocystitis atrophy and total lacrimal duct inflammatory changes, leading to the total lacrimal duct into the lacrimal sac Department atresia, the contents of the cyst can not be discharged, with the accumulation of secretions increased, dilatation and expansion of dacryocyst gradually to form a closed lacunar lacunar lacunar secretions - lacrimal sac. The disease should be distinguished from the dacryocystorhinostosis, although the latter dilatation, but the formation of atresia lacunar, cystic contents can still be discharged through the canaliculus or nasolacrimal duct.
