Glaucoma is a chronic optic neuropathy that causes characteristic visual field defects and is considered one of the leading causes of irreversible vision loss worldwide. Lowering intraocular pressure is the only proven treatment for glaucoma. Medical therapy is usually the first-line treatment for open-angle glaucoma and ocular hypertension. Latanoprostene bunod ophthalmic drop 0.024% is a nitric oxide-donating prostaglandin F2α analog. It lowers the intraocular pressure via a dual mechanism of enhancing aqueous humor outflow through both the trabecular meshwork and uveoscleral pathways. Additionally, the nitric oxide component has shown promise in regulating ocular blood flow and promoting the survival of retinal ganglionic cells. Herein, the mechanism of action, efficacy, safety, and tolerability of the latanoprostene bunod and its effects on ocular blood flow are reviewed. Latanoprostene bunod has demonstrated strong efficacy and a favorable safety profile in both clinical trials and real-world studies. Given the promising results of latanoprostene bunod and advancements in drug delivery, topical fixed-combination and sustained-release formulations containing latanoprostene bunod and other agents targeting different intraocular pressure-lowering mechanisms may become available in the future.
