All 6 cases were associated with lacrimal duct obstruction and infection. Purulent discharge caused by lacrimal duct infection was observed in all 6 patients (100%). However, three of the 6 patients (50%) did not show purulent discharge at initial examination and lacrimal duct obstruction was therefore not initially recognized. Dry eye was observed in five of the 6 patients (83%) and may have caused corneal deterioration, increasing susceptibility to perforation. Further, dry eye masks symptoms of lacrimal duct obstruction and infections, such as epiphora and regurgitation of purulent discharge, making the association with lacrimal duct obstruction and infection difficult to determine. All patients were treated for both corneal perforation and lacrimal duct disease, and conditions improved, with no recurrence of either corneal perforation or lacrimal duct disease.Conclusion: In patients with a combination of lacrimal duct disease and corneal perforation, treatment of both diseases resulted in stabilization of patient condition. Dry eyes may mask symptoms of lacrimal duct diseases, such as epiphora and purulent discharge, and lacrimal duct disease may thus be underdiagnosed.Keywords: corneal perforation, lacrimal duct obstruction, lacrimal duct infection, dacryocystitis, purulent discharge, dry eye, case series
