Back 17

Pink eye

Front 18

What is the difference between conjunctivitis & blepharitis

Back 18

Front 22

What are the 2 types of deafness

Back 22

Nerve & conduction

Front 23

Define the canal of Schlemm

Back 23

Passageway for the aqueous fluid to leave the eye

Front 24

Define Choroid

Back 24

Carries blood vessels, is the inner coat between the sclera & retina

Front 25

Define ciliary body

Back 25

Unseen part of the iris, & these together with the ora serrata from the uveal tract

Front 26

Define the conjunctiva

Back 26

Clear membrane covering the white of the eye (sclera)

Front 27

Define Cornea

Back 27

Transparent portion of the outer coat of the eyeball through which light passes to the lens

Front 28

What is the aperture itself known as

Back 28

Pupil

Front 29

Function of the iris

Back 29

Gives our eyes color & functions like the aperture on a camera, enlarging in dim light & contracting in bright light

Front 30

Define lens, macula & optic nerve

Back 30

Lens help to focus light on the retina

Macula is a small area in the retina that provides our most central, acute vision

Optic nerve conducts visual impulses to the brain from the retina

Front 31

Define ora serrata & posterior chamber

Back 31

Ora serrata & the ciliary body form the unvea tract, an unseen part of the iris

Posterior Chamber is the area behind the iris, but in front of the lens, that is filled with aqueous

Front 32

Define Retina

Back 32

Innermost coat of the back of the eye, formed of light sensitive nerve endings that carry the visual impulse to the optic nerve

Front 33

What is the vitreous

Back 33

Is a transparent colorless mass of soft, gelatinous material filling the eyeball behind the lens

Front 34

Describe Myopia, Hyperopia, Astigmatism

Back 34

Myopia- the incoming light from a far away object focuses before it gets to the back of the eye (nearsightedness)

Hyperopia- incoming light from something far away has not focused by the time it reaches the back of the eye (farsightedness)

Astigmatism- no distinct point of focus inside the eye but rather a smeared or spread out focus.

Front 35

Define 3 eye diseases

Back 35

Glaucoma- a disease of the optic nerve; characterized by a specific pattern of retinal ganglion cell, axon, & optic nerve damage resulting in a reduction in the visual field & even blindness; most significant factor is elevated intraocular pressure

Catarat- clouding of crystalline lens of the eye or its surrounding transparent membrane that hinders or obstructs the passage of light through the lens resulting in blurry, hazy, or distorted vision

Catarat secondary- a clouding of the posterior capsule of the crystalline lens of the eye, following primary cataract extraction, alleviated by penetration with a YAH laser

Conjunctivitis- “pink eye” infection & inflammation of the conjunctiva usually from an allergy a virus or a bacterium

Front 36

describe the parts of the ear

Back 36

Outer- (the part that you see) opens into the ear canal the eardrum separates the ear canal from the middle ear

Middle- small bones in the middle ear help transfer sound to the inner ear

Inner- contains the auditory (hearing) nerve which leads to the brain

Front 37

Define Ossicles

Back 37

3 tiniest bones in the body from the coupling between the vibration of the eardrum and the forces exerted on the oval window of the inner ear.

Front 38

What are the semicircular canals of the ear

Back 38

Located in the inner ear; serve as the body’s balance organ & the cochlea which serves as the body’s microphone.

Front 39

Explain otitis media

Back 39

Mostly caused by the dysfunction of the Eustachian tube, the tube between the nose & middle ear (area behind eardrum) does not work properly. Air cant get through this tube to middle eat . The negative pressure sucks fluid out. Highest incident occurs in preschool children

Front 40

Define ostoclerosis

Back 40

Ear disease in which the otic capsule is replaced in patches by soft bone this soft bone starts growing at the edge of the stapes footplate the stapes cant move like it should & sound is not passed properly from the middle ear to the inner ear creating a conductive hearing loss.

Front 41

Define Meniere’s Disease

Back 41

Caused by an imbalance in the fluid in the sacs in the inner ear. A sudden hearing loss, vertigo, ringing (tinnitus) and or pressure in the ear occur. This disease is episodic & erratic it may progress to total deafness in the affected area.

Front 42

Define Otitis externa (swimmer’s ear)

Back 42

Infection of the outer ear caused by water trapped in the ear canal & bacteria that normally inhabit the skin & ear canal multiply, causing infection & irritation of the ear canal. If infection progresses it may involve the outer ear.

Front 43

Define Deafness

Back 43

Usually involves problems with structures in the outer or middle ear; the latter is a more serious condition resulting from damage to the inner ear or auditory nerve.

Front 44

Two types of deafness

Back 44

Conduction deafness results from a structure in the outer or middle ear not functioning properly. Can be congenital or caused by damage to the ear from injury or infection

Nerve deafness- result in the loss of ability to hear high- frequency sounds, or total loss of hearing,
