ABSTRACT
AIM: To evaluate the effect of probing of lacrimal passage combining injecting of US-produced TobraDex eye ointment for the treatment of chronic dacryocystitis.METHODS: For 127 cases (129 eyes) of chronic dacryocystitis, first the pyoid secretion gathered in the lacrimal sac was dashed out, and some TobraDex was injected in the middle of the lacrimal passage once per day, repeated for several times. The lacrimal passage was probed when the secretion of lacrimal sac disappeared essentially. The lacrimal passage and immit TobraDex eye ointment was used once every two days, repeated for 3-4 times.RESULTS: In 126 cases (128 eyes) the lacrimal passage was dredged. Only one case (1 eye) the youthful patient did not recover for the opening ectopia of lacrimonasal duct.During the 3mo-1a random visit the chronic dacryocystitis did not recrudesce in the cases of lacrimal passage dredging.CONCLUSION: It is simple and safe to use the probing of lacrimal passage combining injecting of US-produced TobraDex eye ointment to treat the chronic dacryocystitis. This method has good curative effects and can keep the normal physiological structure of lacrimal passage. It does not need any expensive medical equipment and cost less, therefore is advisable for patients.
