Most notably, this occurs in partial lacrimal agenesis.
Report of a Case.
—A 3¾-year-old boy presented with a history of bilateral tearing and mucopurulent discharge occurring since 3 months of age. Conservative treatment with massage and antibiotics was unsuccessful. Bilateral probing was also unsuccessful in relieving the symptoms. An increased tear lake was present on both sides, with mucoid reflux. Both inferior puncta were present and normal.

A cutaneous opening of an anlage duct was present on the left.With the patient under general anesthesia, a size-0 Bowman probe was passed from the inferior puncta through a
