Background: The eye is an important sense organ responsible for sight. The cornea is the outermost of many eye layers,being predisposed to several lesions, some of them being frequent in small animal clinics meanwhile others are unusualand seldom reported in specialized literature. The stroma abscess is a common condition in horses, but atypical in dogs,its a condition in which a microperforation in the corneal epithelium allows microorganisms or a foreign body to penetratethe corneal stroma, and those become inside the cornea after a re-epithelialization, producing an intense inflammatoryresponse. Therefore, this case reports a case of deep stromal abscess in a Shih Tzu dog.Case: A 4-year-old female Shih Tzu, weighing 4.6 kg, was submitted to ophthalmic examination in which the left eyepresented an opaque yellowish-white protruding structure located on the right side, in the center of the cornea (3 o´clockposition), bulbar and palpebral conjunctival hyperemia and congestion, chemosis, blepharospasm, and a moderate amountof mucous discharge. The clinical diagnosis was stromal abscess with reflex uveitis. A differential diagnosis should includeconditions affecting the anterior part of the cornea, such as an epithelial inclusion cyst and a corneal ulcer. The inclusioncyst, contrarily to the corneal abscess, doesnt cause pain, meanwhile, the corneal ulcer was ruled out by the FluoresceinStaining Test. The recommended treatment was surgical, through lamellar keratectomy, followed by overlapping pedicledconjunctival graft and third eyelid flap. In association with the surgical treatment, oral antibiotics, anti-inflammatory,and opioids, plus topical antibiotics and autologous serum eye drop. Seventy days post-surgery, the previously observedinflammatory signs were no longer present. In the conjunctival graft insertion site perpetuated a scar leucoma with few...(AU)
