Mean change in the visual field MD from baseline by Humphrey perimetry in study eyes. Test results from eyes that had received rescue IOP-lowering treatment were excluded from the analysis. The number of eyes included in the analysis of change in MD from baseline at visits from week 28 to month 20 ranged from 101 to 143 in the 10 µg bimatoprost implant group, 102 to 143 in the 15 µg bimatoprost implant group, and 123 to 144 in the timolol BID group. *P ≤ 0.037 vs. timolol based on a mixed-effect model for repeated measures including treatment, visit, treatment-by-visit interaction, baseline MD, and visit-by-baseline interaction.
