tårfilmens

Tårfilmens is a Danish noun phrase, generally the possessive form of tårefilm (the tear film). In ophthalmology the tear film is a thin, multi-layered fluid that coats the anterior surface of the eye. The phrase appears in Danish texts as part of phrases such as tårefilmens stabilitet ('the tear film's stability').

The tear film serves several essential functions: lubrication of the cornea, a smooth refractive surface for vision, delivery of nutrients, and protection against infection. It consists of three functional layers: a superficial lipid layer from the meibomian glands; a thicker aqueous layer from the lacrimal glands; and a mucin-containing layer from conjunctival goblet cells. Together they maintain surface wettability and optical quality.

Clinical relevance: disruption of tear film leads to dry eye disease, with symptoms like irritation and blurred vision. Diagnosis uses tests such as tear break-up time (TBUT), Schirmer test, and osmolarity measurements; examination of tear film quality via slit lamp and imaging can assess lipid layer thickness.

Treatment aims to restore tear film integrity and comfort, through artificial tears, lipid-containing lubricants, eyelid hygiene, management of blepharitis, punctal occlusion, and anti-inflammatory therapies when indicated.
