Figure 1. Tear production in different groups with BTX-B injection at different time points after injection. The reduction of aqueous tear production persisted during the observation period in all groups. The tear production of fluorometholone (FML)-treated group tended to increase within 2 weeks, but was not statistically different. (Compared to baseline, the tear production is still significantly lower, p=0.035).
