Figure 1 Change in IOP over time. The average decrease in IOP was 2.77 (4.77) mm Hg from baseline to 2 weeks (9.2% of baseline) (p<0.001). The average decrease in IOP from baseline to 4 weeks was 3.26 (4.11) mm Hg (10.8% of baseline)) (p>0.05) and from baseline to 3 months was 3.74 (4.58) mm Hg (12.4% of baseline) (p>0.05). The average lowering in IOP from 2 weeks to 4 weeks was 0.73 (4.96) mm Hg (p = 0.201). The average decrease in IOP from 2 weeks to 3 months was 1.28 (5.11) mm Hg (p = 0.063).
