We report two rare cases of bilateral acquired canaliculops. A 67-year-old woman and an 89-year-old man showed cystic lesions in the medial-upper eyelid on both sides. In both of the cases, re-canalization using dacryoendoscopy was failed because of firm obstruction at the canaliculus and/or junction between the lacrimal sac and nasolacrimal duct. Although 15 cases with canaliculops had been reported previously, only one congenital case showed bilateral canaliculops. The results of our study indicate more complex obstruction in cases with bilateral canaliculops compared to those with unilateral canaliculops.
我们报告了两例罕见的双侧获得性泪小管囊状扩张。一位 67 岁女性和一位 89 岁男性双侧上眼睑内眦出现囊性病变。在这两种情况下，由于泪小管和/或泪囊与鼻泪管交界处的阻塞较硬，使用泪道内镜进行再通均失败。尽管之前已经报道了 15 例泪小管囊状扩张病例，但只有一例先天性病例表现为双侧泪小管囊状扩张。我们的研究结果表明，双侧泪小管囊状扩张的病例比单侧泪小管囊状扩张的病例存在更复杂的阻塞。
