Results of the Schirmer tear test performed with open and closed eyes in clinically normal horses
BACKGROUND The Schirmer tear test (STT) is widely used in both human and veterinary ophthalmology. Two types of STTs have been developed: STT I and SST II. The STT I measures the basal and reflex tear production and is the most widely used STT. However, several factors influence the STT results such as the person performing the test and the location of the strip placement within the conjunctiva...
متن کاملEffect of acepromazine or xylazine on tear production as measured by Schirmer tear test in normal cats.
OBJECTIVE To evaluate the effect of acepromazine or xylazine on Schirmer tear test 1 results in clinically normal cats. ANIMALS Sixteen healthy cross-breed cats. PROCEDURE The animals were randomly divided into two groups of eight cats each. The first group was sedated with acepromazine alone (0.2 mg/kg) and the second group received only xylazine (2 mg/kg). All cats had Schirmer tear test ...
متن کاملTear meniscus changes during cotton thread and Schirmer testing.
PURPOSE To elucidate the effect of the cotton thread test (CT-T) and Schirmer test (S-T) on the tear reservoir by evaluating the radius of tear meniscus curvature. METHODS The radii (R) of the central lower tear menisci were measured by a newly developed video meniscometer in 11 eyes of 11 normal volunteers (6 men, 5 women; mean age, 27.7 +/- 3.6 years [SD]) and 9 eyes of 9 patients with tear...
متن کاملEffect of temperature and humidity in the Schirmer tear test.
THE Schirmer I tear test developed and standardized by Halberg and Berens, New York City (Contactisol Inc. Lindenhurst, N.Y.) is a useful screening procedure for keratoconjunctivitis sicca in large numbers of patients suffering from various connective tissue disorders. When all the patients attending a centre for rheumatic diseases were subjected to this test it was noted that a surprisingly hi...
متن کاملTear Interferometric Patterns Reflect Clinical Tear Dynamics in Dry Eye Patients.
PURPOSE We investigated whether the tear interferometric pattern was able to identify differences in tear film kinetics among clinical subtypes of dry eye. METHODS A total of 138 eyes of 76 subjects (38 men and 38 women; mean age ± SD, 61.6 ± 16.2 years) with or without dry eye who visited Itoh Clinic from May to August 2015 were enrolled in a cross-sectional study. Clinical diagnosis of dry ...
