Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

* Trial with medical device
