Figures & data
Figure 1 Equivalent IOP-lowering efficacy of brimonidine-Purite 0.1% and brimonidine 0.2%. In a 1-year clinical comparison study of the 2 formulations, the 95% CI of the difference in mean IOP between treatment groups (brimonidine-Purite 0.1% minus brimonidine 0.2%) was consistently within the range of −1.5 mmHg to 1.5 mmHg, demonstrating equivalent efficacy of the study formulations.
Abbreviations: CI, confidence interval; IOP, intraocular pressure.
Figure 2 Mean change from baseline IOP. Both brimonidine-Purite 0.1% and brimonidine 0.2% provided significant IOP reductions that were sustained throughout 1 year of therapy. The mean IOP reduction was equivalent with the 2 formulations throughout follow-up.
Abbreviations: IOP, intraocular pressure.
