Abstract
Congenital dacryostenosis is the most common reason for ophthalmic consultation
in childhood. It is most often caused by persisting of Hasnerʼs membrane.
However, congenital malformations of the lacrimal drainage system can also occur
in rare cases. In the area of the proximal lacrimal drainage system,
supernumerary lacrimal puncta and canaliculi can arise as well as diverticula,
fistula, and atresia. The distal lacrimal drainage system can be affected by
fistulas, amniotoceles, and cysts. Association of lacrimal malformations with
congenital systemic diseases is reported in about 10% of cases. Depending on the
severity of the symptoms, surgical rehabilitation can be performed, and
endoscopic procedures and modern lacrimal drainage intubation systems may be
employed.
