Cochlear implant

Back 4

Amplification device surgically implanted with itsstimulating electrodes inserted directly into the nonfunctioning cochlea.

A unit for measuring the relative intensity of sounds on a scale from 0to 130.

Front 7

Frequency

Back 7

The number of complete fluctuations of energy per second in the form ofwaves.

Front 8

Hyperopia

Back 8

A condition that occurs when light entering the eye isfocused behind the retina; commonly called farsightedness.

Front 9

Myopia

Back 9

A condition that occurs when light entering the eye isfocused in front of the retina; commonly called nearsightedness.

A handheld instrument with a light; used to view innereye structures.

Front 11

Otologist

Back 11

A medical doctor who specializes in the health of the ear.

Front 12

Presbyopia

Back 12

A common eye disorder that results in the loss of lens elasticity. This develops with age and causes a person to have difficulty seeing objects close up.

Front 13

Refraction examination

Back 13

An eye examination in which the patient looks througha succession of different lenses to find out which ones create the clearestimage.

Front 14

Sensorineural hearingloss

Back 14

This type of hearing loss occurs when neuralstructures associated with the ear are damaged. Neural structures includehearing receptors and the auditory nerve.

Front 15

Slit lamp

Back 15

An instrument composed of a magnifying lens combinedwith a light source; used to provide a minute examination of the eye’s anatomy.

Front 16

Tinnitus

Back 16

An abnormal ringing in the ear.

Front 17

Tonometer

Back 17

An instrument for determining pressure or tension,especially determining ocular tension.

Front 18

Whichof the following is the common name for an inflammation of the conjunctiva?

Back 18

PinkEye

Front 19

Droopingof the upper eyelid is known as?

Back 19

Ptosis

Front 20

Anotologist treats which of the following disorders?

Back 20

Mastoiditis

Front 21

Ringingis the ears is known as?

Back 21

Tinnitus

Front 22

The build up of which fluid cause glaucoma?

Back 22

Aqueoushumor

Front 23

Which of thefollowing is not a visual disturbance?

Back 23

Presbycusis

Front 24

Which of thefollowing would be determined by a refraction exam?

Back 24

Astigmatism

Front 25

Which of thefollowing would improve communication with a hearing-impaired patient?

Back 25

Speakin clear, low-pitched tones

Front 26

The units formeasuring the relative intensity of sounds on a scale from 0 to 130 are?

Back 26

Decibels

Front 27

Sensorineuralhearing loss is cause by?

Back 27

Damage to the inner ear

Front 28

Blepharitis

Back 28

A chronic inflammation of the eyelid's edges, more common in older individuals than in younger people. It can be caused by infection or by the same skin condition that causes dandruff. Symptoms include red, swollen eyelids with scaling or crusting of skin at the edges.

Front 29

Ptosis

Back 29

Drooping of the upper eyelid in which the lid partially or completely covers the eye. It is caused by weakness of or damage to the muscle that raises the eyelid or by problems with the nerve that controls the muscle.

Front 30

Sty (external Hordeolum)

Back 30

The result of an eyelash follicle infection. The microorganism most often responsible for the infection is Staphylococcus aureus. A red, painful swelling appears on the eye's edge and typically forms a white head of pus. The head bursts and drains before it heals in about a week. Applying warm, moist compresses to the sty may help it drain sooner.

Front 31

Cataracts

Back 31

Cloudy or opaque areas in the normally clear lens of the eye. Cataracts develop gradually, blocking the passage of light through the eye. The result is a progressive loss of vision in one or both eyes. In severe cases, you can actually see the cloudy lens through the eye's pupil

Front 32

Glaucoma

Back 32

A condition in which fluid pressure builds up inside the eye. This pressure damages the eye's internal structures and gradually destroys vision.

Capillaries in the ciliary body produce aqueous humor—a sticky, watery fluid that circulates between the lens and the cornea.

Front 33

Most common refractive disorders

Back 33

Nearsightedness, farsightedness, presbyopia, and astigmatism.

Front 34

Myopia

Back 34

The condition in which images of distant objects come into focus in front of the retina and are blurred

Front 35

Cerumen impaction

Back 35

A condition called occurs when the ear canal becomes blocked by a buildup of cerumen (earwax).

Front 36

Otitis externa

Back 36

An infection of the outer ear, usually caused by bacteria or fungi. Also known as swimmer's ear, fungal infections are common in swimmers due to persistent moisture in the ear canal. This infection is treated with a combination of antibiotic or antifungal eardrops and an anti-inflammatory medication.

Front 37

Pruritus

Back 37

A common problem in the elderly is —or itching—of the ear canal. Because the sebaceous glands produce less wax with aging, the ear becomes dry and itchy. Dryness can be overcome by a regular routine of lubricating the ear canal with a few drops of mineral oil.

Front 38

Otitis media

Back 38

An inflammation of the middle ear characterized by fluid buildup, most commonly referred to as an ear infection. The Common Ear Infection.

Front 39

Ruptured Eardrum

Back 39

The eardrum may become ruptured in several ways: by a sharp object, an explosion, a blow to the ear, or a severe middle ear infection.

Front 40

Labyrinthitis

Back 40

An infection of the labyrinth, most commonly caused by a virus.

Front 41

Presbycusis

Back 41

A type of sensorineural hearing loss. It is the most common form of hearing loss in older adults, affecting about 25% of people by the age of 60 or 70. Men are affected more often than women. Hearing loss can be treated effectively, however, with a hearing aid.

Front 42

Conductive hearing loss

Back 42

Caused by an interruption in the transmission of sound waves to the inner ear.

Front 43

Sensorineural hearing loss

Back 43

Occurs when there is damage to the inner ear, to the nerve that leads from the ear to the brain, or to the brain itself.

Front 44

Noise Pollution

Back 44

Prolonged exposure to loud noises is a common cause of hearing loss because of damage to the sensitive cells in the cochlea.
