The Schirmer tear test 1 (STT-1) is considered the standard method for quantifying aqueous tear secretion in dogs and other species, 1-4 providing information about the subject's basal tearing, reflex tearing, and lacrimation kinetics. 5, 6 In clinical practice, STT-1 is often repeated at different visits over time; as such, it is important for . The measurement of tear production is an important diagnostic test when deficiency of the lachrymal system is suspected. The Schirmer tear test (STT) devised by Otto Schirmer a century ago is widely used in both human and veterinary ophthalmology as a basic assessment of tear production . Two types of STTs have been developed: STT I and STT II.
