Primary open angle glaucoma (POAG) is the most common type of glaucoma, and is responsible for approximately 90% of glaucoma cases in North America. POAG is characterized by an asymptomatic onset, where patients do not present with symptoms until significant visual loss occurs in late stages of the disease. Importantly, while glaucoma is associated with several risk factors that contribute to damage and disease progression, intraocular pressure (IOP) is the only proven modifiable risk factor at this time. Treatments for POAG include use of pharmacologic and surgical interventions. As of this writing, available pharmacologic options reduce IOP through reduction of aqueous humor production or by facilitating aqueous humor drainage through the uveoscleral outflow pathway (the unconventional pathway). Although cholinergic agonists (eg, pilocarpine) indirectly targets aqueous humor draining through the trabecular meshwork/Schlemm's canal (the conventional outflow pathway), cholinergic agonists are not frequently used, and as of this writing, no agents are currently available that target both the conventional and unconventional outflow pathways. Therapies in late-stage development include trabodenoson, netardsudil, and latanoprostene bunod.
