This study aimed to carry out the clinical and histopathologic characterization of ocular bulbs from dogs and cats, surgical removed as clinical indication between 2005-2015. Hundred-one procedures were performed, 93 enucleations (92%) and 8 exenterantions (8%). The procedures were performed on 80 dogs (79% of cases) and 21 cats (21% of cases). The dogs underwent to surgery had ocular perfuration (n=31, 39%), glaucoma (n=19, 24%), ocular protrusion (n=13, 16%), diagnosis suggestive of neoplasia (n=10, 12, 5%) and other (n=3, 2.97%). Among the clinical diagnosis cats comprise ocular perforation (n=9, 49%), glaucoma (n=3, 14.2%), microphthalmia (n=3, 14.2%), suggestive of neoplasia (n=2, 9.5%), ocular protrusion (n=2, 9.5%) and other (n=2, 9.5%). Twenty-seven samples of ocular bulbs were sent for histopathologic evaluation in Veterinary Pathology Laboratory, being 23 from dogs and four cats. Among the samples of dogs, seven exhibited histopathologic findings compatible with glaucoma, seven ocular perforations, six had intraocular neoplasias, two panoftalmites and condition of Phthisis bulbi. The ocular bulbs of cats received the diagnosis of two intraocular neoplasias, one microphthalmia and ocular perforation. It was found that the secondary glaucoma and ocular perforations are among the leading causes of enucleation in dogs, and associated with primary disorders such as keratoconjunctivitis sicca and uveitis. These disorders, unlike neoplasia, may have therapeutic success through early diagnosis and treatment, preventing blindness and removal of the eyeball. |
