Glaucoma, a group of ocular diseases characterized by progressive damage to the optic nerve, is the second leading cause of blindness worldwide, affecting a significant and growing portion of the US population.1,2
Much remains to be understood about the pathophysiology of glaucoma, but intraocular pressure (IOP) has been identified as an important causative factor and modifiable risk factor.3 As demonstrated in several large clinical trials, IOP reduction can prevent progression of optic nerve damage and visual field loss in both early and late stages of the disease.4,5
Despite multiple drug choices, however, current data shows that a significant proportion of glaucoma patients do not reach target IOP with a single-agent regimen.6,7 Even if pressure is maintained within target levels, some patients may continue to develop progressive glaucoma damage and field loss. These treatment challenges highlight a continued need for more effective therapies.
The conventional trabecular meshwork pathway is the primary route of aqueous outflow in the human eye and the site of extra resistance that results in elevated pressure in primary open-angle glaucoma.8 Even so, therapies targeting trabecular outflow have largely been lacking: the medications that are currently used to treat glaucoma reduce IOP primarily by modulating aqueous production or uveoscleral outflow.
Latanoprostene bunod, a nitric oxide (NO)-donating prostaglandin F2α receptor agonist, is a novel glaucoma drug with a unique dual mechanism of action, achieved by chemically fusing two moieties— latanoprost and an NO donor—into one molecule.9 While latanoprost increases uveoscleral outflow like other PGAs do, the NO donor contributes to IOP lowering by increasing aqueous outflow through the trabecular meshwork.10
To give their glaucoma patients the full benefit of treatment advances, clinicians require clear, actionable insights from knowledgeable subspecialists and researchers. Nitric Oxide in Glaucoma: What Clinicians Need to Know will distill and organize findings about the role of NO in glaucoma and the role NO donation in glaucoma therapy in order to make them accessible to ophthalmologists and medical optometrists who want to optimize their decision-making in glaucoma.
