Ocular surface flora culture swabs were collected for microbiology in four salamanders. Rocuronium bromide (50\u2009\u03bcL; 0.01\u2009mg) was administered into each eye in three salamanders. Pupil size and constriction ability were evaluated up to 60 min following administration of rocuronium bromide.
