AIM： To evaluate the effectiveness of the Crawford tube in treating symptomatic epiphora without nasolacrimal obstruction. METHODS： A protocol was adopted for the management of symptomatic epiphora without nasolacrimal obstruction. Patients who suffered symptomatic epiphora without nasolacrimal obstruction in both eyes were included in the study. One eye was treated with Crawford tube intubation and the other eye was treated with medication therapy. Degree of watering, patient satisfaction, and symptomatic improvement were carefully evaluated by one of the authors at the end of the follow-up period, after Crawford tube removal, to ascertain functional results. RESULTS： Thirty-seven adult patients （37 eyes） underwent Crawford tube intubation for functional epiphora. The mean follow-up time after removal of the tube was 14.8 ~4.8mo. The procedure was an overall success in 28 eyes （75.7%）, with symptoms improving significantly. Two eyes （5.4%） were relieved of indoor epiphora, two （5.4%） had minimal epiphora outdoors, but only with wind or cold, and five （13.5%） continued to experience tearing both indoors and outdoors. Thirty of the patients （81%） expressed satisfaction with the procedure. CONCLUSION： Crawford tube insertion is an effective, safe, simple, and relatively noninvasive treatment strategy for functional lacrimal system obstruction.
