Síndrome ocular do cão braquicefálico - Relato de caso

Abstract

As brachycephalic dogs have peculiar facial anatomical characteristics, they are prone to ophthalmic disorders, with the brachycephalic ocular syndrome becoming increasingly common, comprising medial entropion, macropalpebral fissure, caruncular trichiasis and nasalskin fold trichiasis. However, this eye condition can become even more complicated when itis associated with other diseases of the ocular surface, such as keratoconjunctivitis sicca (CCS), which are also common in dogs of such breeds. This paper reports the clinical case ofa Pug dog, with several alterations that make up the ocular syndrome associated with keratoconjunctivitis sicca (CCS), and its numerous sequelae on the ocular surface, such as corneal edema, pigmentation and neovascularization. We also report the surgical techniquesof medial canthoplasty and nasal fold exeresis used to correct the affections, as well as the technique of lateral canthoplasty, used later, in order to further reduce the palpebral fissure. The purpose of the report is to alert veterinarians about the high frequency of ocular brachycephalic syndrome, which can be complicated by its association with other diseases of the ocular surface. It also emphasizes the importance of early diagnosis to avoid irreparable corneal changes that can damage the animal's vision.
