It was reported a case of a 9-year-old Brazilian Fila male dog that had been affected by a tissular formation of the nictitant membrane of the right eye with four months of evolution. Conjunctival hyperemia and edema, serosanguinolent secretion, and a conjunctival neoformation at the nictitant membrane were observed. Surgical exeresis of the neoformation was performed. Endothelial cells slightly differentiated and pleomorphic, with an intense vascular neoformation compatible to nictitant membrane hemangiosarcoma, were found at the histological exam.

This study aimed to evaluate the effectiveness of a computer-assisted ultrasound analysis of senile dogs cataractous lens and identify its correlation to phacoemulsification surgical parameters. Simultaneous A-and B-mode ultrasonic evaluation of the lens was performed on 15 dogs with cataract. A computer-assisted image analysis was used to objectively calculate the lens echogenicity. Following ultrasonographic examination the cataracts were removed by phacoemulsification and the ultrasonographic and phacoemulsification findings were compared to identify possible correlations. Lens echogenicity obtained by the computer-assisted ultrasonographic analysis correlated to the phacoemulsification time, such that the whiter the ultrasound image, the longer was the phacoemulsification time. The B-mode ultrasonography was helpful for the prediction of lens opacity location, but not predictive of lens hardness.

A two and a half-year-old female Persian cat was presented with a history of bilateral chronic ocular discharge. Epiphora bilateral mucous ocular discharge and a volume increase in bulbar conjunctiva on the dorsolateral quadrant of the right eye were noticed during routine ophthalmic examination. Ophthalmic examination and the aspiration cytology showed the presence of adipose tissue at the right eye dorsolateral quadrant indicating orbital fat prolapse.

A case of a two-year-old male Pinscher with a history of discomfort in the right eye was reported. The left eye had been enucleated by the referring veterinarian due to the same symptom with unsuccessful clinical treatment. The Schirmer tear test value was elevated and a decreased intraocular pressure was observed by applanation tonometry. Biomicroscopy revealed profuse corneal edema and keratoconus and fluorescein staining was negative. Gonioscopy and ophthalmoscopy did not provide any relevant data due to the corneal alterations. Bullous keratopathy was diagnosed. Surgery was performed in two steps: 1) superficial keratectomy and 360º conjunctival flap, and 2) superficial keratectomy to restore corneal transparency. Thirty days after the second superficial keratectomy, the third eyelid flap was removed. Conjunctivalization of the upper nasal quadrant of the cornea was observed. The axial portion of the cornea was transparent and vision was restored.Keywords: dog, bullous keratopathy, superficial keratectomy, 360° conjunctival flap RESUMO Relata
