OSA – Comprehensive eye surface and tear analyser
Meibography is an examination which describes and assesses the number of active Meibomian glands producing the lipid layer of tears, which is responsible for protection against the evaporation of the aqueous layer.
N.I.B.U.T (non-invasive tear film break-up times) is a non-invasive (contactless) measurement of the time it takes the tear film to break up. This parameter allows the stability and integrity of the tear film to be assessed.
Interferometry is a test measuring the thickness of the fatty layer of tears.
Its stability and effectiveness in limiting the evaporation of the aqueous layer depends on its thickness.
Tear Meniscus is a measurement of the height of the lacrimal prism forming between the eyeball and the edge of the lower lid – its height indicates the size of the aqueous layer of the tears.
