Unique technology for automatic and
objective analysis of patients with MGD
Tear film interferometry is increasingly being used in
research to observe the tear film. Interferometry is a technique that studies the surface refractive pattern and dynamics of the lipid layer of the tear film, thus allowing measurement of tear film
stability and lipid layer thickness. Interferometers are investigative toots used in many fields of science and engineering. They are catted interferometers because they work by combining two or more light sources to create an interference pattern, which can be measured and
analysed. The resulting patterns can be mesh and wave. wave only or a fringes of color. SBM Sistemi interferometry studies the amount of lipid content of the tear. The lipid layer is the outermost component of the tear film and allows protection from evaporation of the underlying aqueous layer. The lipid layer is deficient in many MGD patients making this examination extremely important.
