References sometimes vary in their descriptions of .

Schirmer Tear Test (STT) The Schirmer Tear Test (STT) is used to determine the rate of tear production in pets. Tears are produced in the lacrimal gland and the gland of the third eyelid. Tears are important to keep the eyes healthy. If .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.Margadant D L, Kirkby K, Andrew S E et al (2003) Effect of topical tropicamide on tear production as measured by Schirmer tear test in normal cats and dogs. Vet Ophthalmol 6 (4), 315 - 320 PubMed. Other sources of information. Gelatt K N, Gilger B C, Kern T (eds) (2013) Ocular Examination and Diagnostic techniques.Certain dog breeds are predisposed to dry eye. The quantity of tears is measured using a Schirmer Tear Test strip. These are placed on the eye. Normal tear production in the dog is 15-25mm/min. Dry eye is usually treated with a combination of topical lubricants and tear stimulants drugs – cyclosporine, tacrolimus.
Other causes include certain medications, such as long-term administration of oral antibiotics that contain sulfonamide, and genetic factors, such as a gene that predisposes some dogs to be born with abnormally small glands. Diagnosis and Treatment “Most veterinary clinics are able to perform a Schirmer tear test to diagnose dry eye.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.The diagnosis of "dry eye" or keratoconjunctivitis sicca (KCS) may be missed if the Schirmer tear test is not routinely used. The Schirmer tear test measures only the aqueous aspects of tears. Currently, aqueous tear production is most commonly measured using the Schirmer tear test. Schirmer Values: Dog: 21.9 +/- 4.0 mm wetting/minuteThe most common tear production test is the Schirmer tear test (STT). This simple test uses a special wicking paper to measure the amount of tear film produced in one minute. Additional diagnostic tests may include corneal staining to check for corneal ulcers, intraocular pressure (IOP) to determine if glaucoma is present, and tear duct .
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. It measures both basal and reflex tears; placement should be in the middle lower conjunctival fornix.2 o This test is important in cases of corneal ulceration, as patients with KCS are predisposed to ulcers.The Schirmer tear test I (STT) is a method of measuring basal and reflex tear production in animals when deficient tear volume (aqueous component) is suspected. It is performed by inserting a sterile filter paper strip into the lower, middle conjunctival fornix of each eye. . Normal values for dogs are 15 mm/min or greater while normal values .The Schirmer Tear Test (STT) is indicated to measure the rate of tear production. It should be used in the evaluation of conjunctivitis to diagnose tear deficiency as a contributing factor to ocular surface diseases including: Keratoconjunctivitis sicca (KCS), pigmentary keratitis, indolent corneal ulcers, exposure keratitis, and others. If the Schirmer tear test is still showing poor results, the dosing frequency can be increased to three times a day; similarly, if excellent results are seen, the medication can be dropped to once a day. . Dogs with Schirmer tear tests as low as 2mm still have an 80% chance of responding to cyclosporine, though often a higher concentration of .
1 INTRODUCTION. 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 .
Schirmer tear test 1 being conducted in a dog. Values of less than 15 mm/minute wetting of the test trip, in conjunction with the clinical signs seen in Figures 1 through 4, are pathognomonic of the disease. Medical . However, if owners visit their veterinarian as soon as they notice dry eye symptoms, the veterinarian can confirm the condition and provide treatment for their dog. “The diagnosis can be confirmed quickly during the course of a .
A test, called the Schirmer tear test, may be performed to ensure that the eyes are producing enough tears to keep them moist. This is a relatively simple test in which a small paper strip is inserted under the eyelid to measure the amount of moisture produced. Ocular tear production is commonly measured in ophthalmology using the Schirmer Tear Test 1 (STT 1) devised by Otto Schirmer, a German ophthalmologist, about a century ago. To date, the STT 1 remains the standard .tear film (PTF). KCS is cat-egorized by tear film defi-ciency: • Quantitative KCS is a decrease in the aqueous component of the tear film as measured with the Schirmer tear test (STT); it is recognized more commonly in veterinary medicine. • Qualitative KCS is a decrease in the lipid or mucin components of the tear film and diag-nosed by .Purpose: To evaluate and compare three tear sampling methods using two grading scales for administering the tear ferning test (TFT) to healthy dogs. Methods: In total, 90 dogs (180 eyes) were subjected to tear sampling using millimetered strips, reused after the Schirmer tear test (STT) (Schirmer group, SG). Then, the dogs were subdivided into three groups according to .
In the STT II test topical anaesthetic is applied so the STT II will only measure the basal component of the tear film. The STT I and the STT II in the dog are quite different.

Vicki shows use how to do a Schirmer Tear test which measures the amount of tears in a dog's eye.

Schirmer Tear Test Strips. Schirmer tear test strips are used for the quantitative measurement of tear fluid. They are used as a diagnostic tool when “dry eye syndrome” is suspected. Schirmer test strips are designed with an easy-to-read millimetre scale that provides information on the number of tears produced.The diagnosis is easily confirmed by using the Schirmer tear test (STT). The STT, a quick and easy test, should be performed as a routine part of the ophthalmic examination in any dog, but it must be used in every dog of a predisposed breed with conjunctivitis, even with no other clinical signs of dry eye.Routine baseline tests like the Schirmer tear test (STT), fluorescein staining, and tonometry (intraocular pressure [IOP] measurement) are generally performed next. An STT should be performed before any drops are placed on the eye or the eye is cleansed. If indicated, a culture should be taken before any other routine baseline test.
