Final answer:
Miotics like pilocarpine constrict the pupil, which helps reduce intraocular pressure in the short-term treatment of glaucoma.
Step-by-step explanation:
Miotics, such as pilocarpine, are frequently used in the short-term treatment of glaucoma because they can reduce intraocular pressure (IOP) by constricting the pupil. When the pupil constricts, the smooth muscle of the iris contracts, which opens perforations at the base of the cornea and allows for the drainage of aqueous humor. This drainage helps to reduce the pressure inside the eye, which is beneficial for individuals with glaucoma.
