What is Schirmer Tear Test?

The Schirmer Tear Test (STT) is used to measure the rate of tear production in animals. It can be used to diagnose tear deficiency as a contributing factor to ocular (eye) surface diseases, such as Keratoconjunctivitis sicca (KCS), pigmentary keratitis, indolent corneal ulcers, exposure keratitis, and more. It can also be used to assess lacrimal gland function before cataract surgery. Each standardized sterile strip has a color bar tear front indicator and a millimeter scale (up to 35 mm). One package of Schirmer Tear Test contains 5 sets of two strips (one for the left eye and one for the right eye).

For:

Dogs, Cats, Horses, Rabbits

Benefits:

Measures rate of tear production
Comes in sets of two standardized sterile strips for each eye
Has a color bar for an easy measure of moisture
Can be used to diagnose eye diseases

How does Schirmer Tear Test work?

The Schirmer Tear Test measures the rate of tear production by measuring the amount of moisture on the test strip after the test is done.

Cautions:

The Schirmer Tear Tests are intended for single patient use only. Contents are sterile if package is unopened and undamaged. Don’t use if the package has been previously opened. Administration of anticholinergic drugs, such as atropine, can temporarily suppress tear secretion and cause decreased STT value.
