Osa Exams


Evaluation of tear film break-up time non invasive and fully automatic. In the BUT test the presence of fluorescein in the tears may stimulate reflex tearing and may also result in changes to the tear film properties. To overcome these potential limitations, using a non-invasive procedure because the eye is not touched.


Lipid layer

The color and structure of the lipid layer is visible and can be recorder. This shows the lipid layer thickness, which correlates with tear film evaporation and dry eye symptoms.


Bulbar redness classification

Detected the fluidity of the blood vessels of the conjunctivia, evaluating the degree of redness, it will be possible to compare the classification sheets of the degree of redness of bulbar and limbal.


Tear meniscus-height

Evaluation of the tear film quantity.
With a various magnification tools, you can measure the tear meniscus height and evaluate its characteristics along the lower lid margin.



Measurement of the pupil reaction to light with and without glare. Scotopic, Mesopic, Photopic.


Corneal Placid Plate Warpage

Subjective evaluation by the projection of palcido rings.

Tearscope Exams

ICP Dry eye analysis

I.C.P. OSA, the new instrument of individual analysis of lacrimal layers that allow with a quick detailed structural research of the tear composition.
Possibility of researsch on the single layers:
• Lipid
• Aqueous
• Mucin
Thanks to ICP OSA is possible to identify the type of DED(Dry Eye Desease) and determine which deficient layers can be treated with a specific treatment.


ICP OSA allows to quantify directly and indirectly each single layer 

With white LEDs lighting displays in vivo the phenomenon of interference fringes possible to assess the thickness of the lipid component of the tear and run the NiBUT.
With blue LEDs lighting (with the fluorescein) creates a large area and allows you to perform the BUT and look fluorescein of large diameter scleral and mini scleral contact lenses type.


Immediate interpretation and follow up 

Through the use of GRADING SCALE dedicated to each value obtained from the exams, the interpretation of the obtained data results easy and immediate making the iPad a real platform dedicated to the analysis of dry eye with detailed temporal graphics that allow to demonstrate in simple steps the need of the treatments and then the effective functioning of these!

Mucin layer and water layer analysis 

The layer watery is evaluated on the meniscus tear categorizing in different categories and possible issues related this. The measurement in mm allows without invasiveness the direct evaluation of the quantity.


Supplied accessories 

The system is provided with a kit of useful grids to perform various screening, all filters are already present in the system software and includes tests to evaluate and diagnose dry eye problems and can recommend artificial tears.
• Measurement of BLACK LINE (MLMI)
• Evaluation of the integrity of cornea and ascertaining the presence of corneal scars and bruises. The product is already ready for the connection to Digital Imaging and Communications in Medicine (DICOM)
Supplied accessories
• Blue and white Led
• A thick grid to observe the quality of the tear film and measure the N.I.B.U.T.
• A fine grid to evaluate the quality and the structure of tear
• A Placido’s disc to highlight possible distortions or corneal irregularities
• A yellow and cobalt blue filter via software for applicative evaluation of rigid contact lenses.


Analysis lipid layer 

Through a quick and easy acquisition of a series of 3 blinks, ICP Tearscope allows to obtain the thickness of the single Lipid Layer of the tear film classifying it in 7 different categories in a quick and precise way the secretion of the lipids by the Meibomian Glands.
Presence of grading scale and comparison in the time for detailed and precise follow up.
For a detailed analysis of the mucin layer, ICP Tearscope evaluates in both modes the break up time of the lipid layer and, so, the stability through the classic TBUT with possibilities of use of fluorescein in blue light the non-invasive and quick N.I.B.U.T.


Tear meniscus height measurement 

The tear film is the thin layer of liquid (about 8 μ, its thickness is variable on basis the considered portion and it results at maximum at cornea level) composed 98% of water and for the remaining 2% by protein and lipids, that is continuously and uniformly distributed on the ocular surface of the closing of the eyelids and that performs irreplaceable functions for our sight.
In fact it is able to improve the optic quality of the image regularizing the corneal surface (it has an index of refraction of 1,33, very close to that of the cornea); it allows an adequate lubrication reducing the friction of the eyelids, it allows the transport and the diffusion of molecules (oxygen, carbon dioxide, ions, mucins, lipids with a slightly alkaline pH 7,3/7,8), vital elements for the survival of the epithelia and of the cornea, it has strong antibacterial activity thanks to the presence of some enzymes and it guarantees the parts and keeps the ocular surface clean removing impurities from the environment, the waste of metabolism and exfoliated cells.

Palpebral angle measurement

Measurement of the nasal lower palpebral angle useful in the management of the contact lens.

Contact lenses application simulation without fluorescein

Ability to digitally test the CL application from dataase with simulation with fluorescein

White to white measurement

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

Comprehensive and easy to use report off all the examinations related to DED

Benchmarking with Efron, CCLRU and Jenvis boards.
