Parâmetros oftálmicos de cães adultos da raça buldogue francês

Abstract

Brachiocephalic dogs commonly present with ocular changes that are part of the Brachiocephalic Ocular Syndrome, in which shallow orbits, trichinosis of caruncle, exophthalmos, euriblepharon, among others are observed. Among the affected races are the French Bulldogs, whose ophthalmic parameters have not been described so far. The objective of this study was to determine the parameters of ophthalmic diagnosis for dogs of the French Bulldog breed as well as correlate intraocular pressure with systemic arterial pressure. Eleven animals, male and female, from non - commercial breeders from the city of Recife - Pernambuco were evaluated. The examination was started by means of the slit-lamp biomicroscopy, then the Schirmer I tests, the tonometry, the esthesiometry, tear film breakup time, the B-mode ocular ultrasonography, and finally the systemic blood pressure. Biomicroscopy showed changes in 90.9% of the animals, the most common being trichinosis of caruncle (36.3%). There was no significant difference between the right and left eyes in the examinations performed. The mean of the Schirmer I test was 23.27 ± 3.4 mm / min; the mean intraocular pressure was 20.09 ± 3.75 mmHg. The stoichiometry in centimeters was 2.09 ± 0.49 cm. The rupture time of the tear film was 13.23 ± 1.76 s. As to the ecobiometry, the mean of 20.74 ± 0.05 mm for the axial length of the eyeball was obtained. The mean arterial pressure was 114,36 ± 13,13mmHg and it was observed that there was a low correlation between intraocular pressure and mean arterial pressure. It can be concluded that French Bulldog dogs present eye changes compatible with Brachiocephalic Ocular Syndrome and values of ophthalmic parameters are similar to those reported by other authors in studies with brachiocephalic dogs and that there is no correlation between intraocular pressure and systemic arterial pressure.
