ear, nose, & throat

noise-induced hearing loss

otitis media

physical examination; pulmonary embolism; pressure equalizing (tube)

congenital deficiency in color perception; aka color blindness

defective curvature of th cornea & lens, which causes light rays to focus unevenly over the retina rather than being focused on a single point, resulting in a distorted image

degenerative disease in which the lens of the eye becomes progressively cloudy, causing decreased vision

inflammation of the conjunctiva that can be caused by bacteria, allergy, irritation, or a foreign body; aka pinkeye

retinal damage marked by aneurysmal dilation and bleeding of blood vessels or the formation of new blood vessels, causing visual changes

condition in which aqueous humor fails to drain properly & accumulates in the anterior chamber of the eye, causing elevated intraocular pressure (IOP)

most common form of glaucoma that results from degenerative changes thatcause congestion & reduce flow of aqueous humor through the canal of Schlemm

type of glaucoma caused by an anatomically narrow angle between iris & cornea, which prevents outflow of aqueous humor from the eye into the lymphatic system, causing a sudden increase in IOP

small, purulent inflammatory infection of a sebaceous gland of the eyelid; aka sty

breakdown of the tissues in the macula, resulting in loss of central vision

unusual intolerance & sensitivity to light

separation of the retina from the choroid, which disrupts vision & results in blindness if not repaired

muscular eye disorder in which the eyes turn from the normal position so that they divate in different directions

strabismus in which there is deviation of the visual axis of one eye toward that of the other eye, resulting in diplopia; aka cross-eye & convergent strabismus

strabismus in which there is deviation of the visual axis of one eye away from that of the other eye, resulting in diplopia; aka wall-eye & divergent strabismus

benign tumor that develops from the eighth cranial (vestibulocochlear) nerve & grows w/in the auditory canal

decreased ability to perceive sounds compared to what the individual or examiner would regard as normal

total deafness (complete hearing loss)

hearing loss due to an impairment in the transmission of sound because of an obstruction of the ear canal or damage to the eardrum or ossicles

rare disorder of unknown etiology w/in the labyrinth of the inner ear that can lead to a progressive loss of hearng

inflammation of the middle ear, which is commonly the result of an upper respiratory infection (URI)

noninfectious inflammation of the middle ear w/ accumulation of serum (clear fluid)

inflammation of the middle ear w/ pus formation

progressive deafness due to ossification in the bony labyrinth of the inner ear

impairment of hearing that results from the aging process

ringing or tinkling noise heard constantly or intermittently in one or both ears, even in a quiet environment

sensation of moving around in space or a feeling of spinning or dizziness

procedure used to detect glaucoma that measures intraocular pressure by determining the resistanc of the eyeball to indentation by an applied force

standard eye examination to determine the smallest letters a person can read on a Snellen chart, or E chart, at a distance of 20 feet

test that measures hearing acuity at various sound frequencies

visual examination of the external auditory canal & the tympanic membrane using an otoscope

otoscopic procedure that assesses the ability of the tympanic membrane to move in response to a change in air pressure

hearing acuity test performed w/ a vibrating tuning fork that is first placed on the mastoid process & then in front of the external auditory canal to test bone & air conduction

excision of a lens affected by a cataract

excision of the anterior segment of the lens capsule along w/ the lens, allowing for the insertion of an intraocular lens implant

excision of the lens by ultrasonic vibrations that beak the lens into tiny particles, which are suctioned out of the eye; aka small incision cataract surgery (SICS)

surgical transplantation of a donor cornea (from a cadaver) into the eye of a recipient; aka keratoplasty

excision of a portion of the iris used to relieve intraocular pressure in patients w/ glaucoma

electronic transmitter surgically implanted into the cochlea of a deaf person to restore hearing

surgical repair of a perforated eardrum w/ a tissue graft; aka tympanoplasty

incision of the eardrum to relieve pessure & release pus or serous fluid from the middle ear or to insert PE tubes (tympanostomy tubes) in the eardrum via surgery
