Dry Eye Syndrome is a condition involving many factors. The result is a change in the composition of the tears and greater instability of the tear film.
The Tear Osmolarity test allows us to measure how salty the tears are, which indicates the stability of the tear film. This lets us objectively determine the degree of Dry Eye, enabling early diagnosis and also allowing us to assess the effect of medication prescribed by our ophthalmologists.
To obtain this value, a microchip attached to a meter collects a small amount of tear fluid from the edge of the eyelid; the meter is then placed in a reader and, a few seconds later, we obtain the specific Osmolarity value of that tear sample.
