Conjunctivodacryocystorhinostomy (CDCR) success rates and complications in endoscopic vs non-endoscopic approaches: a systematic review.

Background: Epiphora due to refractory bicanalicular obstructions is typically managed by conjunctivodacryocystorhinostomy (CDCR) with or without the assistance of nasal endoscopy. However, the evidence for its benefit is unclear.

Methods: A systematic review of the literature on the treatment of epiphora by CDCR was performed (March 1, 2018).
