ABSTRACT
The present study aimed to evaluate the results of 34 eyes of dogs presenting deep corneal ulcer (n=5), colagenolytic corneal ulcer (n=2), descemetocele (n=7), corneal perforation (n=15), and iris prolapse (n=5) that were corrected by the bulbar conjuntival pedicle graft (CPG). The uveitis score and the corneal integrity were correlated with the presence or absence of vision by contingency tables. Brachycephalic breeds accounted for 91.11% of all cases. The number of perforated corneas [20/34 (58.82%)] were higher than the non-perforated ones [14/34 (41.17%)]. At post-operative day 50, the number of visual eyes with non-perforated corneas before surgery (n=13) did not differ significantly from the eyes with perforated corneas (n=12) (P = 0.05). In half of the cases, uveitis score was considered severe [17/34 (50%)], and in the other half, mild. Eight out of 17 eyes classified with severe uveitis regained vision. In 17 eyes where uveitis score was considered mild, 16 regained vision at the end of the study. Although corneal integrity was non-correlated with the uveitis score (P = 0.48), the number of visual eyes scored with mild uveitis were significantly larger than the eyes with severe uveitis (P = 0.006). In this study, the overall success visual rate after CPG was 73,52% % and the corneal integrity did not play an important role regarding maintenance of vision. However, eyes presenting severe uveitis score had less chance to regain vision.
