Abstract: The aim of this study was to determine physiologic Phenol Red Thread Tear Test (PRT) values in Bozova greyhounds raised in Bozova Province of Sanliurfa, Turkey, in order to investigate possible differences between left and right, males and females eyes. The study was performed on 12 greyhounds ranging from 5 months to 7 years of age and from 11-25 kg body weight. A strip of PRT was placed inside the lower eyelid approximately one-third the distance from the temporal to nasal canthus. For moistening the test strips were left for 15 sec. While the eyelids were held closed. The mean length of the wet area of the strips was 27.79±3.49 mm. There were no significant differences in tear production between males and females or eyes of right and left hand sides. PRT was foud to be a comfortable method which could be easily performed on a routine basis and without pain for measurement of tear production in greyhounds. The normal PRT values found would clinically help diagnosis of Kerato Conjunctivitis Sicca (KCS) in greyhounds.
