It is helpful in the assessment of patients with signs and/or symptoms of dry eye – as it can determine whether surface dryness is due to reduced tear production from the lacrimal glands as opposed to some other cause (e.g. blepharitis, meibomitis, exposure).
The Schirmer tear test is a simple way to measure the moisture level of a dog's eye and his tear production. After a dry eye diagnosis is made, a dog can then begin an artificial tear treatment that corresponds with the severity of the condition.

The Schirmer Tear Test (STT) The STT is used to diagnose keratoconjunctivitis sicca (KCS).

The Schirmer Tear Test 1 (STT1) is a simple test whereby a trip of absorbent paper is placed in the conjunctival fornix for 1 minute, and the distance moisture spreads measured. In cats, high sympathetic tone in clinic and during handling may decrease tear production, leading to erroneously low results and a misdiagnosis of dry-eye. .The Schirmer tear test measures the aqueous portion of the tear film produced by the lacrimal and third eyelid glands. Values are reported in millimeters of wetting per minute. This should be measured before any drops are applied to the eye. A Schirmer I test is used without topical anesthetic and measures baseline and reflex tearing.
Reduced tear production on Schirmer test-2 suggests inadequate basal tear secretion and may indicate underlying dry eye pathology. Clinical Significance: The Schirmer test is an essential component of the dry eye evaluation, providing quantitative information about . The Schirmer test determines whether the eye produces enough tears to keep it moist. Alternative Names.

In theory, it measures only basic secretion when used with anaesthetic. In practice, however, while anaesthetic reduces the amount of reflex secretion, it does not eliminate it completely. Environmental .
Tear Break-up Time The patient is asked to blink after the placement of the fluorescein in the eye. Normally, the tear film breaks up after 15 seconds. Anything shorter may indicate a deficiency in the mucus component .
Schirmer Tear Test I (STT) o The STT is the first diagnostic test, as this should be done before applying any medications to the eye.
