Final answer:
Antiglaucoma drugs such as acetazolamide and pilocarpine are used to treat glaucoma by reducing intraocular pressure, either by decreasing fluid production or improving drainage.
Step-by-step explanation:
Many types of antiglaucoma drugs, usually in the form of eye drops, are used to treat glaucoma. Glaucoma is a condition characterized by the accumulation of fluid in the eye, leading to increased intraocular pressure. Drugs like acetazolamide work by inhibiting the enzyme carbonic anhydrase, which reduces the formation of aqueous humor and aids in the excretion of water through urine, thus lowering intraocular pressure. Another treatment option is pilocarpine, a muscarinic agonist, which contracts the ciliary muscle, promoting the drainage of aqueous humor and reducing pressure in the eye.
