The tear osmolarity test has been proposed as a test for dry eye disease. [33] Tear osmolarity may be a more sensitive method of diagnosing and grading the severity of dry eye compared to corneal and conjunctival staining, tear break-up time, Schirmer test, and meibomian gland grading. [ 34 ]
Schirmer test = 0,00 in Sjögren's syndrome. The test works by the principle of capillary action, which allows the water in tears to travel along the length of a paper test strip in an identical fashion as a horizontal capillary tube. The rate of travel along the test strip is proportional to the rate of tear production.

[ 3 ] It is commonly caused by types 8 and 37 adenoviruses , spread by contaminated eye examination instruments and eye solutions, touching eyes by infected people, from inadequately chlorinated ...
Around 10% of respiratory infections in children are caused by adenoviruses. [10] Most are mild and by the age of 10-years, most children have had at least one adenovirus infection. [2] Adenoviruses are the most common viruses causing an inflamed throat. [16] 75% of conjunctivitis cases are due to adenovirus infection. [13]
