Dacryocystitis , the inflammation of lacrimal sac and duct has been known from the earliest times due to its grosser manifestations involving cosmetic defects on face. For a long time, swelling near the medial canthus was considered as a soft tissue infection known as “Aegylops”. It was in the middle of the first century that it could be recognized as a disease of the lacrimal passage when Versalius and Fallopius22 described the lacrimal sac with accuracy. George E Stahl23 showed that the pathological manifestations were dependent on inflammation of the nasolacrimal canal; these manifestations were of three forms - acute, chronic and with ulceration or fistula.
