Impacto do grau de uveíte em diferentes tipos de úlceras de córneas em cães submetidos ao enxerto pediculado de conjuntiva bulbar : 32 casos

Abstract

The presente study aimed to evaluate the results of 24 eyes of dogs presenting deep corneal ulcer (3), Descemet membrane exposure (6), Descementocele (1), corneal perforation (10) and iris prolapse (2) that were corrected by the bulbar conjuntival graft (BCG). The uveitis score and the corneal integrity were correleted with the presence or absence of vision with the Fisher exact test. The number of nonperforated corneas (12/24; 50%) was equal to the perforated ones. 5/12 perforated eyes regained vision and 5/12 remanined blind at day 20 after surgery. The number of perforated eyes did not differ significantly from the unperforated ones (P = 0.3707). Regarding the uveitis score, 13/24 (54,16%) eyes were considered severe, and 11/24 (45,83%), were considered mild. 7/13 eyes scored with severe uveitis regained vision and 6 remained blind. All of the 11eyes were the uveitis score were considered mild regained vision at the end of the study.The number of visual eyes scored with mild uveitis were significantly larger than the others (P = 0.0059). It was concluded that corneal integrity (perforated vs unperforated) did not play a role over the recovery of vision in dogs operated by the BCG. However, one should consider that eyes scored with severe uveitis had a significantly less chance to regain vision.
