We compared in two controlled studies the effect of pilocarpine 1% with the effect of pilocarpine 1% combined with 0,05% or 0,1% dipivalyl-epinephrine in patients with open-angle glaucoma. The pressure reducing effect of pilocarpine 1% was significantly increased and prolonged by the combination with dipivalyl-epinephrine. 0,1% dipivalyl-epinephrine + pilocarpine 1% did not have a more significant pressure reducing effect in our patients than 0,05% dipivalyl-epinephrine + pilocarpine 1%, but the reduction of pressure persisted longer. It is a considerable advantage in glaucoma therapy to diminish or to avoid systemic and local side effects of epinephrine due to very low concentrations of dipivalyl-epinephrine.
