AIM: To investigate the effect of unilateral hole blunt lacrimal probe for neonatal dacryocystitis topical anesthesia.

METHODS: Seventy-five children(86 eyes), among 4-month or 5-year-old, who had dacryocystisis, were treated by dacryocystitis massage for one month. But it was invalid. Then blocking lacrimal passages were flushed under conventional pressure. Later, unilateral hole blunt lacrimal probes was used to make lacrimal passages open under topical anesthesia. After operation, lacrimal passages were flushed three times every two days.

RESULTS:Eighty-four cases were cured and no recurrence with only once treatment. Two cases were cured with the second treatment. All cases were without infection and no complications as false passages and lacrimal points were appeared. After 3-month followed up, none of them was relapsed.

CONCLUSION:Using unilateral hole blunt lacrimal probe for neonatal dacryocystitis under topical anesthesia is effective.
