O.S.A. is the entry level instrument for the individual analysis of tear film that allows to carry out a quick detailed structural research of all the layers (Lipid, Aqueous, Mucin) and Meibomian Glands

Thanks to the O.S.A. it is possible to identify the type of Dry Eye Disease (DED) and determine which components can be treated with a specific treatment, in relation to the type of deficiency.

LIST OF AVAILABLE EXAMS

The OSA can evaluate the quantity and quality of the lipid component on the tear film.
The device highlights the lipid layer and the user can evaluate the quality and the thickness.

The thickness of the tear meniscus that is observed on the eyelid margins provides useful information on the tear volume.
The tear meniscus can be examined considering its height, regularity and shape.

The stability of the mucin layer and the whole tear film is assessed through the study of the break up time (BUT)
or non-invasive break up time (NIBUT), by using the Placido cone projected onto the cornea.

Meibography is the visualization of the glands through illumination of the eyelid with infrared light.
It images the morphology of the glands in order to diagnose any meibomian gland drop out which would lead to tear dysfunction.

This test helps to visually see blepharitis and presence of Demodex. It can be performed on the outer surface of the eye and eyelids.

Once the image of the conjunctiva with its blood vessels is captured, it is possible to compare it with the classification sheets of bulbar and limbal redness degrees.

Measurement of the pupil reaction to light with and without glare. Measurement mode: SCOTOPIC,  MESOPIC, PHOTOPIC

Evaluation of corneal diameter from limbus to limbus (white-to-white distance, WTW).
