Feedback:
Glaucoma is an eye disease characterized by increased pressure in the eye—known as intraocular pressure (IOP)—which can cause optic nerve atrophy and blindness. Diuretics are used to provide osmotic pull to remove some of the fluid from the eye, which decreases IOP, or as adjunctive therapy to reduce fluid volume and pressure in the cardiovascular system, which also decreases pressure in the eye somewhat. Potassium sparing refers to a class of diuretics that help to retain potassium.
