Dacryocystorhinostomy (DCR) is used for treating lacrimal duct obstruction and can be performed with an external (EXT) or an endoscopic (END) approach. In this case report a 70-year-old woman suffering from chronic epiphora had earlier been treated with exploration of the lacrimal duct with insertion of a silicone tube. Due to continuous epiphora the patient underwent END DCR revision surgery, where a 4-cm silicone tube was retrieved from the distal part of the lacrimal duct. If EXT DCR was used for revision surgery, most likely the silicone tube in the lacrimal duct would not have been found.
