ÚLCERA DE CÓRNEA EM CÃES: relato de caso

Abstract

Corneal ulcer or ulcerative keratitis is one of the most frequent ophthalmic pathologies that affect dogs. The cause is basically the injury and inflammation of the layers of the cornea, which is the outermost structure of the eyeball. Thus, corneal ulcers in dogs can be characterized according to depth, dimension and etiology, and can be classified into superficial, deep and corneal perforation. The clinical signs of the disease can be identified by ocular discomfort, frequent tearing, blepharospasms and photophobia. The diagnosis will be defined through anamnesis, complete ophthalmic examination and testing with fluorescein. Therefore, treatment varies according to the classification of the disease, using medications to aid healing and various surgical techniques. The present work aimed to report a surgical clinical case of deep corneal ulcer with exposure of the descemet layer, classified as descemetocele, in a female canine, treated at the Crystal Life Pet Veterinary Clinic. The tutor reported that the patient had discomfort in her right eye. On specific physical examination, when evaluating the right eye bulb, opacity, conjunctival hyperemia, deep vacularization, blepharospasm, tearing and secretion were observed. A fluorescein teste was performed and with the aid of a cobalt lamp, the patient was diagnosed with descemetocele. For treatment, corneal-conjunctival transposition was indicated. Therefore, the surgical technique proved to be effective, repairing, and preventing the progression of descemetocele and consequently corneal rupture.
