Used primarily in the treatment of open-angle glaucoma and ocular hypertension, this chemical effectively reduces intraocular pressure by increasing the outflow of aqueous humor through the uveoscleral pathway. It is administered as an ophthalmic solution, typically once daily in the evening, to maximize its pressure-lowering effect. Due to its prostaglandin analog properties, it may also cause gradual changes in eye color and eyelash growth with long-term use. Its efficacy, convenience of dosing, and well-tolerated profile make it a first-line therapy in chronic glaucoma management.
