Current medical therapy for primary open-angle glaucoma is limited toward lowering intraocular pressure. A rational approach to choosing antiglaucoma medications should minimize the number of medications and the probability of significant adverse effects.

If one medication is not adequate in reaching the target pressure, a second medication should be chosen that has a different mechanism of action, so that the 2 drug therapies will have an additive effect.
