IOP Lowering Effect of PLT Versus SLT in Naiv OAG Patients
Effect of Patterned Laser Trabeculoplasty on Intraocular Pressure Compared to Selective Laser Trabeculoplasty in Treatment Naiv Patients Suffering From Open-angle Glaucoma or Ocular Hypertension

To investigate the effect of patterned laser trabeculoplasty (PLT) compared to selective laser trabeculoplasty (SLT) on intraocular pressure (IOP) in treatment naiv patients suffering from open-angle glaucoma or ocular hypertension.

Values for IOP will be measured at baseline, 1 day and 1 month post-interventional as well as 2, 3, 6, 9, 12, 18 and 24 months after treatment.
