This study will investigate if micropulse laser trabeculoplasty (532nm) is as effecttive as or better than the conventional laser trabeculoplasty (532nm), it might be a new treatment strategy for glaucoma patients. It is done with a laser device that can also be used for many other ophthalmic applications, thus reducing the economic burden of treatment.
