Ocular surface disorders in dogs and cats submitted to dissociative anesthesia in elective orchiectomy procedure

The present study aims to verify whether dogs and cats submitted dissociative anesthesia for elective orchiectomy may alterations in the tear production consequent lesions on ocular surface. For this purpose, 40 animals, 22 18 dogs, underwent an ophthalmic semiotechnique composed of evaluation anterior posterior chambers, fundscopy, Schirmer's test (TLS) fluorescein test. Subsequently, they anesthesia, associating ketamine with diazepam or midazolam. Immediately at end procedure, TLS was repeated. After 24 hours, a new performed compare results obtained. There were no changes. With use diazepam, remained within normal range median 19 mm / min, mean standard deviation 19.27 ± 3.01 min 19.05 2.81 cats. When using midazolam, had 18.84 2.69 cats, 18.37 2.32 min. found suggest that short procedures does not significantly alter production, nor it cause eye injuries.
