 | | Although diverticulum of the lacrimal sac may occur, a congenital fistula of the lacrimal sac, which has been termed lacrimal anlage duct by Jones, is more common. |
 | | Congenital atresia, supernumerary or double puncta, and congenital slits of the puncta all may occur. |
 | | Tearing and mattering: Newborns who have congenital dacryostenosis may not develop acute dacryocystitis with a mucocele or pyocele of the sac in the early neonatal period but may simply have tearing with a chronic mucopurulent discharge, which usually manifests at 2 weeks. |
