The cause of acquired lacrimal drainage obstruction may be primary or secondary. Primary acquired nasolacrimal duct obstruction results from inflammation of unknown cause that eventually leads to occlusive fibrosis. Secondary acquired lacrimal drainage obstruction, the theme of this report, may result from a wide variety of infectious, inflammatory, neoplastic, traumatic, or mechanical causes. An etiologic classification system for acquired lacrimal drainage obstruction is proposed, and it is illustrated by representative patients from the author's practice and discussed with reference to published reports.
获得性泪道阻塞的病因可能是原发性的或继发性的。原发性获得性鼻泪管阻塞源于不明原因的炎症，最终导致闭塞性纤维化。继发性获得性泪道阻塞是本报告的主题，可能由多种感染性、炎症性、肿瘤性、外伤性或机械性原因引起。本文提出了一种获得性泪道阻塞的病因分类系统，并通过作者临床实践中的典型病例进行说明，并参考已发表的报告进行讨论。
