AIM To compare the outcomes achieved with external dacryocystorhinostomy (EX-DCR) and transcanalicular dacryocystorhinostomy (TC-DCR) using a multidiode laser in patients with bilateral nasolacrimal duct obstruction (NLDO). METHODS This prospective study was conducted on 38 eyes of 19 patients with bilateral NLDO. Simultaneous bilateral surgery was performed on all patients. TC-DCR (Group 1) ...

The sump syndrome was initially described in relation to patients who had undergone external dacryocystorhinostomy. Here we report a case of sump syndrome that developed following laser conjunctivodacryocystorhinostomy (CDCR) due to tube displacement after a bout of forceful sneezing.
