Abstract
This is a retrospective study of data analyses from 201 cases with keratoconjunctivitis sicca (KCS) referred to the National Taiwan University Veterinary Hospital, Taiwan. There were 23 breeds in the study, with three most affected breeds, namely Shih-Tzu, Maltese and American cocker spaniel, making up 59.2% of the cases. Among all cases, the mean age at onset of clinical signs was eight years and one month, with no statistical difference between females and males. Clinical signs consisted mainly of corneal pigmentation, mucopurulent discharge and corneal ulceration. In contrast, Shih-Tzu and Malteses showed higher incidence of corneal ulceration. Severe corneal pigmentation occurred in Shih-Tzu. There was no significant difference in mucopurulent discharge in all breeds. The results of this study revealed interbreed differences with respect to sex, age and risks of corneal pigmentation, and corneal ulceration that have not been detailed previously in a referral population in Taiwan.
