Pilocarpine is frequently used in ophthalmology to treat glaucoma. What is its primary effect on the eye?
Show answer and explanation
Correct answer: Miosis and decreased intraocular pressure
Pilocarpine stimulates muscarinic receptors on the pupillary constrictor muscle, causing miosis, and on the ciliary muscle, causing contraction. This opens the trabecular meshwork, facilitating the drainage of aqueous humor and lowering intraocular pressure.
