The Schirmer tear test (STT) provides a vital measurement in all animals as part of an initial ophthalmic examination. For years, the use of the STT with cats was controversial, with low STT values being interpreted as indicative of cat stress (Lim et al., 2009). In a clinical setting, the STT is the primary quantitative tear test. Abstract OBJECTIVE To assess reliability of the Schirmer tear test-1 (STT-1) for measurement of tear production in cats in various environments, investigate whether sympathetic stimulation impacts . The Schirmer tear test (STT) is commonly used in small animal ophthalmic examinations to quantify the aqueous component of tears. 7,8 Several factors can influence the test results, . Sebbag et al 18 also found that stress does not decrease tear production. In fact, the cats under stress conditions showed a trend for an increase in lacrimal .

The Schirmer tear test (STT) is the most common diagnostic test for assessing aqueous tear production in dogs. 4 Schirmer tear test-1 (STT-1) is performed without topical anesthesia to provide an estimate of the basal and reflex tear production. 4 The distal end of the strip is bent in the plastic cover (to avoid contamination from the examiner .Small Animals Investigation of Schirmer tear test-1 for measurement of tear production in cats in various environmental settings and with different test durations Lionel Sebbag DVM OBJECTIVE To assess reliability of the Schirmer tear test-1 (STT-1) for measurement of Lisa K.

Schirmer strips provide a repeatable method to quantify lacrimal TPC in dogs and cats, although care should be taken to absorb sufficient volumes of tears to minimize the concentrating effect from the absorbent material. BackgroundQuantification of lacrimal total protein content (TPC) is an important tool for clinical scientists to understand disease . Abstract Objective—To determine reference values, intertest correlations, and test-retest repeatability of Schirmer tear test 1 (STT-1), phenol red thread test (PRTT), tear film breakup time (TFBUT), tear osmolarity, and meibometry in healthy cats. Design—Evaluation study. Animals—135 healthy domestic cats aged 0.5 to 12.8 years. Procedures—Each test .Test reliability was good although test-retest repeatability was generally poor to moderate, as depicted by low intraclass correlation coefficients (ICC ≤ 0.75) and wide 95% limits of agreement, except for CTS (ICC = 0.91). Conclusions: Corneal sensitivity and aqueous tear secretion are lower in brachycephalic dogs. A comprehensive assessment .Sebbag, Lionel Kass, Philip H Maggs, David J Publication Date 2015-02-15 DOI 10.2460/javma.246.4.426 . Objective—To determine reference values, intertest correlations, and test-retest repeat-ability of Schirmer tear test 1 (STT-1), phenol red thread test (PRTT), tear ﬁlm breakup time (TFBUT), tear osmolarity, and meibometry in healthy cats.

The Schirmer test or Schirmer tear test (STT) is used to assess tear production, especially in patients with suspected keratoconjunctivitis sicca, dry eye, or tear overproduction. 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 .

This study used a noninvasive method of tear measurement (the Schirmer tear test, STT) to quantify values for basal and reflex tearing and to determine the kinetic nature of tear production in 76 New Zealand white rabbits to provide preliminary evidence for an interaction effect between eyes. Rabbits are a common animal model in eye research and in safety . Schirmer tear test-1 (STT-1) is considered the gold standard method for measuring tear production; however, it does not measure tear quality . The tear ferning test (TFT) is a qualitative test developed for humans, and it has become a useful diagnostic tool in tear ferning research. . Sebbag L, Kass PH, Maggs DJ.

Sebbag L, Leonard BC, Saito A. Vet Ophthalmol. 2023 Apr; 26 Suppl 1:5-15. Epub 2022 Dec 27. 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 .

Design—Evaluation study. Based on the Schirmer test (Sebbag et al., 2020), no significant difference in tear production was found among cats examined at a private practice, clinic, and hospital. Another study suggested that the Schirmer tear test and strip meniscometry are viable options for evaluating cat tear production ( Kovaļčuka et al. , 2021 ).Dr. Sebbag obtained his veterinary medical degree (DVM) from the National Veterinary School of Toulouse. . diagnostic test results and response to therapy of cats with Schirmer tear test 1 (STT .

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. Abstract Purpose: The study establishes normative data of tear volume (TV) and tear turnover rate (TTR) in healthy dogs and cats, 2 species commonly used for translational research in ophthalmology. Methods: Thirty-six dogs and 24 cats were enrolled, encompassing a variety of breeds with diverse skull conformations (brachycephalic, mesocephalic, and .

Age, sex, breed, and reproductive status were recorded. Schirmer tear test (STT) and TBUT were assessed in all dogs, and interferometry was available for the selected dogs. The Jones test was used to evaluate NLD patency. The cephalic index (CI) was calculated for each dog (skull width/skull length ×100). ResultsTen dogs and 10 cats were enrolled in the study.
