Which emergency medication would be used for glaucoma therapy in dogs to increase uveoscleral outflow?

Latanoprost is an effective medication used to manage glaucoma in dogs primarily because it enhances uveoscleral outflow, which is critical in reducing intraocular pressure. By acting on specific receptors, Latanoprost increases the permeability of the uveoscleral pathway, facilitating the drainage of aqueous humor from the anterior chamber of the eye to the venous circulation. This mechanism is particularly beneficial in situations where intraocular pressure needs to be lowered rapidly and effectively.

While other medications may play roles in glaucoma management, they do not specifically target uveoscleral outflow in the way Latanoprost does. For example, Dorzolamide is a carbonic anhydrase inhibitor that decreases aqueous humor production rather than increasing outflow. Prednisolone is a corticosteroid that can reduce inflammation and could be indirectly beneficial in some cases of secondary glaucoma, but it does not directly affect outflow. Mannitol is an osmotic agent used to lower intraocular pressure by temporarily pulling fluid out of the eye, but it does not increase uveoscleral outflow.

Therefore, Latanoprost stands out as the choice that directly addresses the need to improve drainage through the uveoscleral pathway, making it the preferred
