We performed endoscopic dacryocystorhinostomy to treat idiopathic naso-lacrimal duct obstruction in 14 cases. The light guide facilitated adequate fenestration of the lacrimal sac safely and easily. All patients had successful outcomes without hyperlacrimation. For the treatment of idiopathic naso-lacrimal duct obstruction, light-guided endoscopic dacryocystorhinostomy is considered more useful than external dacryocystorhinostomy.
