Canaliculops is a rare condition, and only 11 cases have been reported previously. We report 2 cases of canaliculops, which were successfully treated using the new recanalization technique under dacryoendoscopy followed by bicanalicular lacrimal intubation.
A 78-year-old man and a 76-year-old woman had 3- and 1-year histories of medial-upper eyelid swelling (left and right, respectively) without any inflammatory signs, history of periocular trauma, herpes infection, use of specific drugs, or ophthalmic diseases of note.
The cystic lesions were evaluated using ultrasound biometry or computed tomography to find the lumen of the horizontal canaliculus was exceedingly expanded, and to confirm the clinical diagnosis of canaliculops.
As the 2 cases of canaliculops were caused by upper puncta and common canaliculus obstructions, canaliculops of the upper eyelid were recanalized under dacryoendoscopic guidance, followed by bicanalicular intubation. The tubes were kept in situ involving bi-weekly irrigation and instillation of antibiotic and anti-inflammatory eye drops, and were removed after 2 to 3 months of follow-up.
Epiphora, and eyelid swelling were completely resolved immediately after the procedure, and the lesions did not recur on follow-up after more than 6 months.
Eleven case series of canaliculops have been described previously, but this is the first report of this recanalization procedure offering a new, less invasive treatment option compared to complete or partial resection of the cystic lesion.
Canaliculops 是一种罕见的疾病，此前仅报道过 11 例。我们报告了 2 例 Canaliculops 病例，通过泪道内窥镜下的新再通技术联合双泪小管插管治疗获得成功。
1 例 78 岁男性和 1 例 76 岁女性，分别有 3 年和 1 年的病史，表现为上眼睑内侧肿胀（左眼和右眼），无炎症迹象、无眶周外伤史、疱疹感染史、使用特定药物史或其他眼部疾病史。
使用超声生物测量或计算机断层扫描评估囊性病变，发现水平泪小管的管腔极度扩张，从而确诊 Canaliculops。
由于这 2 例 Canaliculops 是由上泪小点和总泪小管阻塞引起的，在泪道内窥镜引导下对其进行再通治疗，随后进行双泪小管插管。在原位保留导管，每周进行两次冲洗和滴注抗生素和抗炎眼药水，在随访 2 至 3 个月后将其取出。
术后即刻溢泪和眼睑肿胀完全缓解，随访 6 个月以上未见病变复发。
此前已有 11 个关于 Canaliculops 的病例系列报道，但这是首例关于再通程序的报道，与囊性病变的完全或部分切除相比，该程序提供了一种新的、创伤更小的治疗选择。
