We present two patients with dacryoliths and patent lacrimal drainage with intermittent tearing and without infection. Dacryoliths can be present in the lacrimal sac or lacrimal duct without acute or chronic inflammation. In these cases, we believe dacryolith formation was a causative factor of intermittent epiphora even with a patent drainage system, and we propose that dacryoliths and even fungal colonization formation may be the first event before dacryocystitis and should be considered as a cause of epiphora.
我们报告了两名患有泪石且泪道通畅、有间歇性流泪且无感染的患者。泪石可存在于泪囊或泪管中，而无急性或慢性炎症。在这些病例中，我们认为即使泪道引流系统通畅，泪石形成也是间歇性溢泪的一个致病因素，并且我们提出泪石甚至真菌定植形成可能是泪囊炎之前的首要事件，应被视为溢泪的一个原因。
