3 layers of the globe
globe, choroid, and retina
the surrounding structures of the eye
adnexa: orbit, eye muscles, eyelids, eyelashes, conjunctiva, and lacrimal apparatus
common diseases of the eye
ulcerative keratitis, uveitis, glaucoma, KCS, conjunctiva
things to consider for topical eye meds
absorbed into anterior chamber, can be ointment or solution, easy to administer
topical anesthetics
proparacaine and tetracaine; used for eye exams, or to remove foreign materials
test to determine corneal defects
fluorescein sodium
miotics
constrict the pupil, treat glaucoma by increasing outflow of aqueous humor
example of miotics
pilocarpine
mydriatics and cycloplegics
dilate the pupil, paralyze ciliary muscles to reduce pain
examples of mydriatics
atropine, phenylephrine, tropicamide
carbonic anhydrase inhibitors
to treat glaucoma, interfere with production of carbonic acid that decreases aqueous humor production
examples of carbonic anhydrase inhibitors
acetazolamide, dorzolamide, dichlorphenamide, methazolamide
beta-adrenergic blockers
treat glaucoma, decrease production of aqueous humor
examples of beta-adrenergic blockers
timolol and betazolol
osmotic diuretics
decrease vitreous humor, mannitol and glycerin
drugs to treat uveitis
flurbiprofen (treat underlying condition)
treat KCS
artificial tears, antibiotic-steroids, cyclosporine
treat ulcerative keratitis
flurbiprofen, antibiotics (ending in mycin), serum, cycloplegic
other drugs to treat eye diseases
antibiotics, antifungals, antivirals, corticosteroids, NSAIDS
outer ear
pinna and external canal
middle ear
tympanic membrane, ossicles, eustachian tube, oval window, round window
inner ear
vestibule, cochlea, semicircular canals
drugs to treat ear disease,
anti fungal, biotic, parasitic, corticosteroids, otic drying agents, cleansing agents, and dewaxing agents
