Clinical epidemiological analysis of entropion in dogs and cats: retrospective study (2013-2020) in the veterinary hospital of the federal University of Jataí

Entropion is characterized by the inversion of the eyelid margin. It can affect the upper eyelid, the lower eyelid or both, be unilateral or bilateral and manifest a series of clinical eye signs in dogs and cats. Given the clinical importance of entropion, this study aimed to analyze the clinical and epidemiological aspects of this important disease in dogs and cats that were attended and surgically treated in the Veterinary Ophthalmology Department of the Veterinary Hospital of the Federal University of Jataí in the period from 2013 to 2020. Weight, gender, species, breed and age of patients diagnosed and treated for entropion were also evaluated, in addition to the main clinical signs presented. In the period, entropion corresponded to 6.2% of the total number of the casuistry in ophthalmic care. No sexual predisposition was found for ophthalmopathy. 89, 2% were canine and 10.8% were feline. In this clinical epidemiological study, it was found that the most affected canine breeds are Shar-Pei and Chow Chow. Shar-Pei dogs, almost in their entirety, presented the alteration prior to the first year of life. In both dogs and cats, the most common clinical signs were epiphora, conjunctival hyperemia, ocular discharge, blepharospasm and pruritus. All cases were treated with surgical intervention.
