Zusammenfassung
Zur Aufrechterhaltung der okulären Oberflächenhomöostase und damit den Erhalt der
optischen Eigenschaften sind Tränenproduktion, -verteilung und -abtransport essenzielle
physiologische Funktionen. Störungen dieser funktionellen Einheit gehen mit starken
Beschwerden und einem hohen Leidensdruck bei den Patienten einher. Da etwa 3% unserer
Patienten eine Tränenabflussstörung aufweisen, ist die Thematik von hohem klinischem
Interesse.
Abstract
The tearing eye (epiphora) is the guiding symptome of nasolacrimal duct obstruction.
Depending on the localization of stenosis, mucopurulent lacrimal discharge occurs
additionally. These symptoms induce alterations of the optical system and can cause
severe complications such as acute phlegmonous dacryocystitis. The grade of suffering
in these patients is very high. For the diagnosis, patientʼs history, ocular surface
conditions and inspection (macro-/microscopically) as well as palpation of the lacrimal
region are essential examinations. Moreover, functional and anatomical tests enable
a classification of nasolacrimal duct obstruction regarding grade of stenosis (incomplete
vs. complete), type (functional vs. mechanical), and localization (pre-, intra-, postsaccal).
ENT consultation prior to lacrimal surgery is obligate. Through this, a purposeful
therapeutic intervention is warranted. Surgical methods consist of minimally invasive
transcanalicular procedures or
anastomosing surgeries. Dependent on the clinical findings, these treatment options
can be applied in a patient centered therapeutic concept.
