Miotics and Mydriatics Flashcards
a rare condition where you have two rows of eyelashes
dystichiasis
what does fluorescence stain diagnosis
traditional ulcers
what is lissamine green used to diagnose
cornea damage
tear production
what is phenol red thread used to diagnose
tear production
what is rose bengal used to diagnose
viral keratitis
what is the schirmer tear test used to diagnose
tear production
four uses of ocular topical anesthetics
Anesthesia of the surface of the cornea
Facilitate the removal of a foreign body
Allow examination behind the third eyelid
Facilitate use of a Schiotz tonometer or TonoPen
preferred topical ocular anesthetic
proparacaine
how long will anesthesia last with proparacaine
5 - 10 mins
where does proparacaine live and why
in the fridge - to keep the solution thicker
which topical ocular anesthetic is more irritating
tetracaine
what can topical anesthetics do to healing
may delay it
produce pupillary constriction
miotics
what nervous system induces miosis
parasympathetic
two ways that miotics reduce IOP
increase the outflow of aqueous humor
increase tear production
primary use of miotics
glaucoma
second use of miotics
KCS
miosis
primary miotic drug used for glaucoma and post cataract removal
carbachol
miotic drug not commonly used because it is more irritating
pilocarpine
miotic drug that reduces glaucoma IOP for up to 48 hours
demecarium bromide
do not use demecarium bromide in what kind of animals
pregnant animals
an agent that dilates the pupil
mydriatics
what are mydriatics known as
alpha 2 agonist
what nervous system induces a mydriatic response
sympathetic
what do mydriatic drugs decrease
IOP
mydriasis
mydriatic drug that decreases aqueous humor production (glaucoma)
apraclonidine (Iopidine)
what mydriatic drug is longer duration and less irritating
brimonidine (alphagan)
which mydriatic drug is given as an intracameral injection
epinephrine
what does epinephrine help to prevent
bleeding from intraocular surgical procedures
injection directly delivers the drug into the anterior chamber of the eye
intracameral injection
