abnormal condition of eye fungus
corneal abrasion
scraping injury to cornea
ophthalmoscopy
examination of interior of eye
Study of the eye
Ophthalmology (Ophth)
Equilibrium
Contains Semicircular canals, utricle, and saccule
otopyorrhea
discharge of pus from ear
Otology (Oto)
Study of the ear
Ossicles
Tympanic membrane vibrates incus, vibrations amplify as they move, staples transmits vibration to oval window (start of inner ear)
ceruminoma
excessive accumulation of earwax forming hard wax plug
HEENT
head, eyes, ears, nose, throat
iris
the contractile, circular diaphragm forming the colored portion of the eye and containing a circular opening, the pupil, in its center.
falling test
assesses equilibrium; balancing one one foot with eyes open and the closed
presbyopia
visual loss due to old age
hordeolum
purulent infection of sebaceous gland of eyelid; also called a stye (so sty)
presbycusis
normal loss of hearing with age
Organ of sight, that transmits external image using sensory impulses via optic nerve to brain, and brain translates sensory impulses into image.
Eyeball
cochlear
a spiral-shaped cavity forming a division of the internal ear in humans and in most other mammals.
pupil
the expanding and contracting opening in the iris of the eye, through which light passes to the retina.
fluorescein angiography
injection of fluorescein dye into bloodstream to observe blood flow within eye
fluorescein staining
applying fluorescein eye drops to cornea to look for corneal abrasions
Eustachian Tube
Also called auditory tube, connects nasopharynx with middle ear, opens with each swallow, and equalizes pressure between middle ear cavity and atmospheric pressure
Cerumen
Produced by oil glands in auditory canal and oily wax slowly flows out of ear canal removing dirt that has stuck to it
Behind iris, not actually part of choroid layer and attached to ciliary body
Lens
Meniere's disease
progressive hearing loss, vertigo, and tinnitus; causes not well understood
acoustic neuroma
benign tumor of cochlear nerve; symptoms include tinnitus, headache, dizziness, and hearing loss
glaucoma
abnormally high fluid pressure in the eye, most commonly caused either by blockage of the channel through which aqueous humor drains
chronic
(of a disease) having long duration (
radial keratotomy (PK)
spoke-like incision around cornea to flatten it; treats myopia
Opening in center of iris and allows light to enter into eyeball
Pupil
audiometry
test of hearing ability in regards to both intensity and pitch person is able to hear
otitis externa (OE)
external ear infection; often by fungus; also called otomycosis or swimmer's ear
Contains sensory receptors for hearing and equilibrium (balance)
Function of ear
esotropia (ST)
type of strabismus with inward turning of eye; also called cross-eyed
cryoextraction
use of extremely cold probe to lift cataract from lens
color vision tests
use of multicolored charts to determine ability to recognize colors
macular degeneration
deterioration of macula lutea area of retina
optic
of or pertaining to the eye or sight.
myopia
a condition of the eye in which parallel rays are focused in front of the retina, objects being seen distinctly only when near to the eye; nearsightedness (
Sensorineural hearing loss
Damage or malformation of inner ear (cochlea) or the cochlear nerve and sounds are distorted because nerve impulse is incorrect
laser-assisted insitu keratomileusis (LASIK)
correction of myopia using laser surgery to remove corneal tissue
astigmatism
a refractive error of the eye in which parallel rays of light from an external source do not converge on a single focal point on the retina.
amblyopia
loss of vision not as a result of eye pathology; commonly called lazy eye
Six muscles that connect eyeball to skull and contract in combination to change direction in which each eye is looking
Muscles of the eye
