PURPOSE: To assess the usefulness of sequential probing for diagnosing lacrimal canalicular @entity850 , and the effectiveness of bicanalicular @entity1346 intubation after sequential dilatation in treatment. METHODS: Canalicular @entity850 was diagnosed by sequential probing in 22 @entity1 (22 eyes) who were misdiagnosed as @entity3885 . The @entity1 were treated by bicanalicular @entity1346 intubation after sequential dilatation. Anatomical improvements and functional relief of @entity9467 were evaluated. In addition, complications were evaluated. RESULTS: The average age of the 22 @entity1 was 57  years, and the average follow-up period was 13  months. The @entity1346 tube was left in place for an average of 14  weeks. The anatomical success rate was 100  %. Fifty-four percent of @entity1 achieved complete relief of @entity9467 , 32  % partial relief, and 14  % no relief. There were no complications. CONCLUSIONS: Sequential probing is an useful diagnostic method for canalicular @entity850 . Bicanalicular @entity1346 intubation after sequential dilatation is a simple and effective treatment, and could be performed as primary procedure for canalicular @entity850 before invasive surgery.
