What does pilocarpine do to the eye?
Ophthalmic pilocarpine is used to treat glaucoma, a condition in which increased pressure in the eye can lead to gradual loss of vision. Pilocarpine is in a class of medications called miotics. It works by allowing excess fluid to drain from the eye.
What is Miotic used for?
A muscarinic cholinergic agonist used on the eye to treat elevated intraocular pressure, various types of glaucoma, and to induce miosis. Also available orally to treat symptoms of dry mouth associated with Sjogren’s syndrome and radiotherapy.
What is an example of a Miotic drug?
Pilocarpine is one of the more commonly used agents in this class. Less frequently used miotics include phospholine iodide (0.03%, 0.06%, 0.125%, 0.25% qd/bid) and carbachol (0.75%, 1.5%, 3% tid/qid).
What are Mydriatics and miotics?
Pupil constriction (miosis) can either be stimulated by contraction of the iris sphincter or by relaxation of the iris dilator. On the other hand, pupil dilation (mydriasis) can either be stimulated by contraction of the iris dilator or by relaxation of the iris sphincter.
How long does pilocarpine take to wear off?
Miosis usually persists for 4-8 hours, rarely, up to 20 hours. Reduction of intra-ocular pressure is evident within 60 minutes, peaks within 75 minutes and, depending on the concentration of pilocarpine used, persists for 4-14 hours.
Does pilocarpine dilate the eye?
Pilocarpine is a medication used to reduce pressure inside the eye and treat dry mouth. As eye drops it is used to manage angle closure glaucoma until surgery can be performed, ocular hypertension, primary open angle glaucoma, and to bring about constriction of the pupil following its dilation.
Where should Miotics be placed when administered?
The patient should be placed in a supine position to allow posterior migration of the lens, and be given an oral hyperomotic agent and topical anti-hypertensive drops. If the lens becomes trapped in the pupillary aperture or in the anterior chamber, the patient should be placed supine and the pupil dilated.

What are miotic eye drops?
Miotics are eye drops that cause the pupil to constrict, allowing the blocked drainage angle to open. They may be used two, three, or four times daily. These medications are now reserved for use in people whose glaucoma does not improve with other medications. Miotics may cause some eye discomfort and redness.
What drugs act as Driatic?
Most commonly used mydriatics are phenylephrine hydrochloride and tropicamide.
How do mydriatic drops work?
Dilating drops work by blocking parasympathetic receptors in the iris sphincter, allowing the iris dilator to act unopposed and enlarge the pupil. (The pupil dilates mostly because it can’t constrict.) This parasympathetic input also controls accommodation, or changing focus of the eye for near objects.
