Chapter 12 non word part

Question 1

Reduced vision in one eye caused by disuse or misuse associated with strabismus, unequal refractive errors, or otherwise impaired vision. The brain suppresses images from the impaired eye to avoid double vision. (also called lazy eye)

Answer 1

Amblyopia

Question 2

Blurred vision caused by irregular curvature of the cornea or lens. Light refracts improperly, resulting in diffused, rather than points of light focusing on the retina.

Answer 2

Astigmatism (Ast)

Question 3

Clouding of the lens of the eye.

Answer 3

Cataract

Question 4

Farsightedness

Answer 4

Hyperopia

Question 5

Eye disorder characterized by increase of intraocular pressure (IOP). If left untreated may progress to optic nerve damage and visual impairment or loss.

Answer 5

Glaucoma

Question 6

Nearsightedness

Answer 6

Myopia

Question 7

Poor vision at night or in faint light (also called night blindness).

Answer 7

Nyctalopia

Question 8

Involuntary, jerking movement of the eyes.

Answer 8

Nystagmus

Question 9

Impaired vision as a result of aging.

Answer 9

Presbyopia

Question 10

Separation of the retina from the choroid in the posterior portion of the eye.

Answer 10

Retinal detachment

Question 11

Condition in which the eyes look in different directions; caused by dysfunction of the external eye muscles or an uncorrected refractive error (called cross-eyed when one eye turns in).

Answer 11

Strabismus

Question 12

Infection of an oil gland of the eyelid.

Answer 12

Sty

Question 13

Progressive deterioration of the portion of the retina called the macula, resulting in loss of central vision.

Answer 13

ARMD – Age Related Macular Degeneration

Question 14

Surgical removal of the eyeball (also, the removal of any organ that comes out clean and whole).

Answer 14

Enucleation

Question 15

Laser procedure that reshapes the corneal tissue beneath the surface of the cornea to correct astigmatism, hyperopia, and myopia.

Answer 15

LASIK (laser-assisted in situ
keratomileusis)

Question 16

Method to remove cataracts in which an ultrasonic needle probe breaks up the lens, which is then aspirated.

Answer 16

PHACO – phacoemulsification

Question 17

Procedure for the treatment of astigmatism hyperopia, and myopia in which an excimer laser is used to reshape (flatten) the corneal surface by removing a portion of the cornea.

Answer 17

PRK – photorefractive keratectomy

Question 18

Artificial lens implanted within the eye during cataract surgery.

Answer 18

Intraocular lens (IOL)

Question 19

Agent that constricts the pupil.

Answer 19

Miotic

Question 20

Agent that dilates the pupil

Answer 20

Mydriatic

Question 21

Specialist who fills prescriptions for lenses (cannot prescribe lenses).

Answer 21

Question 22
