N.I.B.U.T

To evaluate the tear film break-up time in a non invasive and fully automated way. In the B U T test the presence of fluorescein in the tears may stimulate reflex tearing and may also change tear film properties.
To overcome these potential inconvenients a non-invasive procedure may be used.
In the dog and the cat third eyelid movements may prevent NIBUT exam.

OSA Veterinary Exams

Lipid layer

EVALUATION OF THE LIPID LAYER THICKNESS
The color and structure of the lipid layer is visible and can be recorded.
The lipid layer pattern depends on its thickness, which correlates with tear film evaporation and dry eye clinical signs.

Tear meniscus-height

In dogs and cats the PTF thickness is about 8 μ on the cornea but it is much thicker at the meniscus, where in human being reaches up to 0,2 to 0,5 mm (200- 500 μ).
By examining the meniscus it is possible to evaluate the lacrimal gland acqueous production.

Corneal Placid Plate Warpage

To evaluate corneal distortion and tear film defects by the projection of Placido rings on ocular surface.

Tearscope Veterinary Exams

ICP Dry eye analysis

I.C.P. Tearscope is an instrument available to veterinary ophthalmologists and practitioners 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:

  •  Lipid
  • Aqueous
  •  Mucin

Thanks to ICP Tearscope it is possible to identify the type of DED and determine which deficient layer is affected and select a specific treatment.

ICP OSA allows to quantify directly and indirectly each single layer 

The white LEDs are used to display the phenomenon of interference fringes, allowing to evaluate the thickness of the lipid component of the tear and run the Break Up Time ( NIBUT) and Non Invasive Dehydration Up Time (NIDUT).
The blue LED (when using fluorescein) allows you to observe the bulbar or corneal staining and run the Break Up Time (BUT).
By evaluating the tear meniscus, it is possible to directly perceive and measure the PTF watery component.

Lipid analisys 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 3 to 5 different categories in a quick and precise way.
It is possible to refer to a grading scale for detailed classification and follow up.
For a detailed analysis of the mucin layer, ICP Tearscope evaluates the non invasive break up time and the lipid layer. By matching the two exams it’s possible to better evaluate the stability of the precorneal tear film.
By using the fluorescein stain, it’s possible to perform the classic TBUT.

Supplied accessories 

The system is provided with a kit of useful grids to perform various screening. All filters are already present in the Tearscope.
• Measurement of BLACK LINE (MLMI)
• Evaluation of the corneal surface to check for irregular patterns and structural defects
• Blue and white Led
• A thick grid to observe the quality of the tear film
• A fine grid to evaluate the quality and the structure of tear and measure the N.I.B.U.T.
• A Placido’s disc to highlight possible distortions or corneal and tear film irregularities

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

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

Specific reports per exam
