Figure 2. Effect of BTX-B on murine corneal staining. Corneal fluorescein staining scores. Data represents the mean±SEM in all groups. Average score in BTX-B injected mice was significantly increased compared with control and saline-injected mice at all time points (p<0.01). X–axis: time after injection.
