A retrospective study of the results obtained from surgical treatment after canaliculus injuries during the period 1981 to 1987 at the Munich University Eye Hospital. The surgical treatment involved a ring intubation of both canaliculi with a silicone rod inserted with a pigtail probe (Kellnar probe). In 45 patients with an average follow up period of 2.1 years we found a 91% success rate with anatomical reconstruction of the injured canaliculus. Although the lacrimal passages were patent, 4% of these patients complained of epiphora. We analyse the circumstances of the injury, the age of the patient and complications. The discussion includes a review of relevant literature.

The paper compares the preoperative localization of stenosis in the lacrimal passage after digital dacryocystography with the operative findings in 23 eyes of 22 patients in the years 1988 to 1991 at the Munich University Eye Hospital. In a very high percentage (95.6%) there is a positive correlation. The discussion shows the advantages of the method and includes a review of relevant literature.
