RationaleCanaliculops 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.Patient ConcernsA 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.DiagnosesThe 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.InterventionsAs 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.OutcomesEpiphora, and eyelid swelling were completely resolved immediately after the procedure, and the lesions did not recur on follow-up after more than 6 months.LessonsEleven 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.Copyright © 2021 the Author(s).
