72 months was 14.7 ± 1.8 mmHg (range 10–21 mmHg) for primary open-angle glaucoma and 13.2 ± 1.3 mmHg (range 12–15 mmHg) for juvenile glaucoma. The IOP drop for both groups was statistically highly significant (p<0.001) at all measured post-operative intervals (see Figures 4 and 5). Pressure reduction at any time of standardised follow-up was statistically significant compared with pre-operative data at a level of α<0.03 (Bonferroni-corrected). In the juvenile

glaucoma group, with five patients there are not enough cases to get conclusive statistics but the results show the tendency.
At month 72 after surgery, 52.8 % of patients with open-angle glaucoma had an IOP <15 mmHg, 76 % had an IOP <18 mmHg and 79.2 % had an IOP <21 mmHg (see Figure 6); 80 % of patients with juvenile glaucoma had an IOP <15 mmHg and 100 % had an IOP <18 mmHg. After 72 months, 84.9 % achieved >20 % reduction in IOP and 77 % of treated patients with open-angle glaucoma achieved >30 % reduction of IOP.
