Tear osmolarity testing dry eye diagnosis system OSA Vet

meibographytear meniscometry

A full assessment of the ocular surface through a combination of tests for dry eye diagnosis, from tear break up time to the tear volume production test. ICP OSA-VET DRY EYE ANALYSIS OSA-Vet is an instrument available to veterinary ophthalmologists to evaluate the composition and stability of the Precorneal Tear Film (PTF). It allows to better evaluate PTF qualitative deficiencies and make an accurate diagnosis of evaporative Dry Eye Disease (DED) due to imbalance of the three main PTF components: Lipids, Aqueous, Mucins. Thanks to OSA-Vet it is possible to identify the type of DED, determine which déficient layer is affected and select a specifie treatment. TEAR FILM LIPID LAYER EXAMINATION The scattered light emitted by the OSA-Vet system allows to evaluate the interference patterns coming from the Lipid Layer (LL) of the tear film. The différent patterns can be classified according to LL thickness and quality. OSA-VET ALLOWS TO QUANTIFY DIRECTLY AND INDIRECTLY EACH SINGLE TEAR FILM LAYER The white LED allows to show the phenomenon of interference fringes, that depends on the different thicknesses of the lipid layer of the tear film. IMMEDIATE INTERPRETATION AND FOLLOW UP By using a dedicated lipid layer grading scale, each interference pattern may be examined in a simple and straightforward way. SUPPLIED ACCESSORIES The system is provided with a kit of useful grids to perform various screenings. Ail filters are already présent in the OSA-Vet package. - A thick grid to observe the quality of the tear film. - A fine grid to evaluate the quality and the structure of tear film and measure the N.I.B.U.T.
