  1. Absolute values (percentage).
  2. n sample size.
  3. * Two patients developed filtering blebs after canaloplasty and were therefore excluded.
  4. + Two patients needed cyclodestruction to reach target IOP and were therefore excluded.
  5. ~ One patient underwent cyclophotocoagulation to lower IOP and was therefore excluded.
  6. a χ 2-test (Fisher´s exact test).
