26
salping/o
tube (usually fallopian or eustachian [auditory] tubes)
27
-acusis
hearing
28
achromatopsia
congenital deficiency in color perception; also called color blindness
29
astigmatism
defective curvature of the cornea and lens, which causes light rays to focus unevenly over the retina rather than being focused on a single point, resulting in a distorted image
30
cataract
degenerative disease in which the lens of the eye becomes progressively cloudy, causing decreased vision
31
conjunctivitis
inflammation of the conjunctiva that can be caused by bacteria, allergy, irritation, or a foreign body; also called pinkeye
32
diabetic retinopathy
retinal damage marked by aneurysmal dilation and bleeding of blood vessels or the formation of new blood vessels, causing visual changes
33
glaucoma
condition in which aqueous humor fails to drain properly and accumulates in the anterior chamber of the eye, causing elevated intraocular pressure (IOP)
34
hordeolum
small, purulent inflammatory infection of a sebaceous gland of the eyelid; also called a sty
35
macular degeneration
breakdown of the tissues in the macula, resulting in loss of central vision
36
photophobia
unusual intolerance and sensitivity to light
37
retinal detatchment
separation of the retina from the choroid, which disrupts vision and results in blindness if not repaired
38
strabismus
muscular eye disorder in which the eyes turn from the normal position so that they deviate in different directions
esotropia: cross-eye, convergent strabismus
exotropia: wall-eye, divergent strabismus
39
acoustic neuroma
benign tumor that develops from the eighth cranial (vestibulocochlear) nerve and grows within the auditory canal
40
hearing loss
decreased ability to perceive sounds compared to what the individual or examiner would regard as normal
anacusis: total deafness
conductive: 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.
41
Meniere disease
rare disorder of unknown etiology within the labyrinth of the inner ear that can lead to a progressive loss of hearing
42
otitis media (OM)
inflammation of the middle ear, which is commonly the result of an upper respiratory infection (URI)
- - serous: noninfectious inflammation of the middle ear with accumulation of serum (clear fluid)
- - suppurative: inflammation of the middle ear with pus formation
43
otosclerosis
progressive deafness due to ossification in the bony labyrinth of the inner ear
44
presbycusis
impairment of hearing that results from the aging process
45
presby-
old age
46
tinnitus
ringing or tinkling noise heard constantly or intermittently in one or both ears, even in a quiet environment
47
vertigo
sensation of moving around in space or a feeling of spinning or dizziness
48
tonometry
procedure used to detect glaucoma that measures intraocular pressure by determining the resistance of the eyeball to indentation by an applied force
49
visual acuity test
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
50
audiometry
test that measures hearing acuity at various sound frequencies
51
otoscopy
visual examination of the external auditory canal and the tympanic membrane using an otoscope
pneumatic: otoscopic procedure that assesses the ability of the tympanic membrane to move in response to a change in air pressure
52
Rinne test
hearing acuity test performed with a vibrating tuning fork that is first placed on the mastoid process and then in front of the external auditory canal to test bone and air conduction
53
cataract surgery
extraction of a lens affected by a cataract. the central part of the lens is removed and replaced with an artificial introcular lens (IOL) implant
54
extracapsular cataract extraction (ECCE)
excision of the anterior segment of the lens capsule along with the lens, allowing for the insertion of an intraocular lens implant
55
phacoemulsification
excision of the lens by ultrasonic vibrations that break the lens into tiny particles, which are suctioned out of the eye; also called small incision cataract surgery
56
corneal transplant
surgical transplantation of a donor cornea (from a cadaver) into the eye of a recipient; also called keratoplasty
57
iridectomy
excision of a portion of he iris used to relieve intraocular pressure in patients with glaucoma
58
cochlear implant
electronic transmitter surgically implanted into the cochlea of a deaf person to restore hearing
59
myringoplasty
surgical repair of a perforated eardrum with a tissue graft; also called tympanoplasty
performed to correct hearing loss
60
myringotomy
incision of the eardrum to relieve pressure and release pus or serous fluid from the middle ear or to insert PE tubes (tympanostomy tubes) in the eardrum via surgery
61
cholesteatoma
tumorlike sac filled with keratin debris most commonly found in the middle ear
62
labyrinth
system of intercommunicating canals, especially of the inner ear
