  1. Mean IOP (mmHg) measured at baseline and all follow-ups after XEN microstent-implantation. Results are reported for the whole group of eyes treated and for the four subgroups of eyes with different glaucoma types. The indicated P-values and mean reduction represent the comparison between the results of the baseline examination and the 12-month results of the respective group
