Glaucoma, Ocular Hypertension and Pseudoexfoliation syndrome have been treated with IOP-lowering medications or surgery to lower the pressure inside the eye to reduce the risk of visual field loss. Today, common treatments for a patient often begins with the prescription of a prostaglandin (Travoprost). If the prostaglandin does not lower the pressure inside the eye enough, a second drug is usually added. Topical carbonic anhydrase inhibitors (Brinzolamide) and alpha 2 agonists (Brimonidine) are common choices as additive medicines.
