For patients already on a PGA, the mean diurnal IOP-lowering achieved with the addition of an alpha2 adrenergic agonist, a beta adrenergic antagonist, or a topical carbonic anhydrase inhibitor is similar, whereas the side-effect profiles, nocturnal IOP-lowering efficacy, and trough IOP-lowering effects vary. Laser trabeculoplasty is also an effective means of further lowering the IOP in patients on a PGA.
