The tests include Schirmer tear test 1 (STT-1), phenol red thread test (PRTT), tear film breakup time (TFBUT), tear osmolality, and meibometry performed in 120 cats at least once and repeated in 40. Tear deficiency should be suspected in cats with STT-1 < 9 mm/min, PRTT < 15 mm/15 s, or TFBUT < 9 to 10 seconds. Generally poor correlation among tests suggested that .

The Schirmer tear test (STT) involves placing the test strip in the lower conjunctival sac for 60 seconds and measuring the amount of wetting in millimeters during this time. This test assesses only the aqueous portion of .
Tear Break Up Time (TBUT) is used to evaluate the tear film quality. To perform this test, apply fluorescein stain to the eye, allow the animal to blink its eyelids, then examine with a cobalt . We encourage clinicians to assess the tear film in cats with ocular surface disease, and initiate therapy with lacrimomimetics if STT-1 values are repeatedly below normal.

Although the mean STT-1 value obtained under stress conditions was within the normal range, stress can influence the test results, and stress increased tear production in cats. Objectives This study aimed to determine the impact of acute stress on tear production in companion cats to provide a basis for minimizing stress-inducing stimuli during ophthalmic .

Background. The purpose of this study was to evaluate the values of Schirmer tear test (STT) and determine effects of age, life stage, sex, breed and neuter status on tear production in healthy cats.Author(s): Sebbag, Lionel; Kass, Philip H; Maggs, David J | Abstract: ObjectiveTo 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.DesignEvaluation study.Animals135 healthy domestic cats aged . The ophthalmic data of 82 healthy adult dogs were evaluated in this study. Procedures. 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 tear film is a trilaminar fluid composed mainly of lipids, electrolytes, proteins and water. . (SCCED), pigmentary keratitis, corneal sequestrum and dry eye syndrome.

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 .

In healthy cats, TFBT decreases significantly after 40 min of general anesthesia, and one drop of 0.15% sodium hyaluronate was able to maintain the stability of the tear film for up to 75 min in treated eyes.There was a positive correlation, both before and after anesthesia, between STT values in both eyes (OU) and tear film BUTs OU, and the isolation or lack of isolation of conjunctival microorganisms using PCR did not significantly affect tear film Buts. The objectives of this study were: (i) to determine tear film breakup times (BUTs) in young healthy cats; (ii) to determine .

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 measurements, and determine whether meaningful conclusions regarding lacrimation in cats can be drawn from STT-1 measurements obtained with STT strip . Introduction. The eye’s surface is covered by the precorneal tear film, which is critical for maintaining a normal, healthy, visual, and comfortable eye (Dilly, 1994; Ohashi et al., 2006).The aqueous portion, the middle layer of the tear film, plays an essential role in providing the necessary ocular surface moisture, a normal nutrient supply, and the oxygenation needed .

The mean TFBUT in cats with conjunctivitis was significantly lower than previously established values for clinically healthy cats, which supports the theory that qualitative tear film deficiency, and thus tear film instability, may play a role in the pathogenesis of feline conjunctvitis.
