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. Unlike cases of external dacryocystorhinostomy where flaps are sutured, there is a potential space created by the sac remnants in laser CDCR. Hence, any displacement of the tube will lead to the improper drainage of secretions with superadded infections of the contents (as occurred in this case). Therefore, in laser CDCR, it is imperative to create an appropriately placed osteotomy with a correctly sized tube that is well secured to avoid displacement along with patient education regarding tube care.
