keratometry
measures curvature of cornea

surgical repair of eardrum
glaucoma
chronic increase in intraocular pressure; results in atrophy of optic nerve
ophthalmoscope
instrument to view inside eye
optician
specialist in grinding corrective lenses
optometry
specializing in examining eyes, testing vision, and prescribing corrective lenses
trachoma
chronic bacterial infection of conjunctiva
otomycosis
abnormal condition of ear fungus
4 muscles pull straight
rectus muscles
antiemetics
treats nausea associated with vertigo
hearing aid
mechanical device used amplify sound
anesthetic ophthalmic solution
eyedrops to deaden pain
monochromatism
unable to perceive one specific color
legally blind
severely impaired vision; having 20/200 acuity
otoscopy
examination of ear canal and eardrum
tympanometry
measurement of movement of tympanic membrane to asses pressure inside middle ear
Labyrinth
Cavity withing temporal bone and houses inner ear
Middle layer, provides blood supply for eye, anterior portion includes the iris, pupil, and ciliary body
Choroid
Anterior portion of sclera, clear, transparent, allows light to enter, and bends or refracts light rays.
Cornea
A mucous membrane, forms continuous covering on underside of each eyelid and across anterior surface of each eyeball also protects eyeball
Conjunctiva
cataract
an abnormality of the eye, characterized by opacity of the lens.
optometrist
a licensed professional who practices optometry.
keratoplasty
surgical repair of cornea with a cornea transplant
retinal detachment
separation of retina from choroid layer; damages blood vessels and nerves causing blindness
phacoemulsification
use of high-frequency sound waves to liquefy lens with cataract which is then removed with a needle
nyctalopia
difficulty seeing in dim light; also called night blindness
Tympanic Membrane
Commonly called eardrum, sound waves strike membrane, causes it to vibrate, and separated external ear from middle ear
2 muscles pull on an angle
Oblique muscles
papilledema
swelling of the optic disk; also called choked disk
astigmatism
blurred vision due to uneven cornea; light rays do not focus sharply on retina
deafness
inability to hear or having some degree of hearing impairment
otitis media
inflammation of the middle ear, characterized by pain, dizziness, and impaired hearing.
cornea
the transparent anterior part of the external coat of the eye covering the iris and the pupil and continuous with the sclera.
ophthalmic decongestant
constricts arterioles of eye to reduce redness and itching
Active in dim light and see gray tones
Rods
anti-inflammatory otic solution
reduces inflammation and itching of otitis extrena
otosclerosis
loss of mobility of stapes bone; leads to hearing loss as it cannot vibrate
How we hear
Sound waves travel down external auditory canal, strike eardrum and eardrum vibrates, ossicles condduct vibrations across middle ear from eardrum to oval window, and oval window movements initiate vibrations in fluid that fills cochlea, fluid vibrations strike hair cells, bending small hairs and stimulating nerve endings, and never ending sends electrical impulse to brain on cochlear portion of vestibulocochlear nerve
achromatopsia
unable to perceive one or more colors; color blind
Upside-down image forms on retina, optic nerve transmits this image to brain, and brain turn upside-down image into right-side up image
How we see
otology
the science of the ear and its diseases.
auditory
pertaining to hearing, to the sense of hearing, or to the organs of hearing.
Both upper and lower edges have these to protect eye from foreign particles
eyelashes (cilia)
Conductive hearing loss
Disease or malformation of outer or middle ear and all sounds is weaker and muffled since it is not conducted correctly to inner ear
laser photocoagulation
use of laser to destroy very small precise areas of retina
Light rays pass through cornea, pupil, aqueous humor, lens, and vitreous humor then strike retina by stimulating rods and cones
How we see
Semi-solid gel located between lens and retina
Vitreous humor (eye fluid)
The Inner Ear
It has Labyrinth which is a cavity within temporal bone and contains sensory organs.
refractive error test
vision test for defect in ability of eye to focus image on retina; tests for hyperopia and myopia
Ear responsible for two senses.
Hearing and equilibrium or sense of balance
