four uses of ocular topical anesthetics
Anesthesia of the surface of the cornea

preferred topical ocular anesthetic
proparacaine

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
