Bilateral acquired canaliculops: Report of two cases

ABSTRACT

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.
