Q

achromatopsia

A

Severe congenital deficiency in color perception; also called complete color blindness

45
Q

ametropia

A

Failure of light rays to focus sharply on the retina as a result of a defect in the lens, cornea, or shape of the eyeball; also called error of refraction

46
Q

astigmatism (Ast)

A

Distorted vision resulting from a defective curvature of the cornea or lens causing light rays to diffuse over a large area of the retina rather than being sharply focused

47
Q

hyperopia

A

Visual defect in which the eyeball is too short, and the image falls behind the retina; also called farsightedness

48
Q

myopia

A

Visual defect in which the eyeball is too long, and the image falls in front of the retina; also called nearsightedness

49
Q

cataract

A

Opacity that forms on the lens and impairs vision, caused by proteins that slowly build up over time

50
Q

chalazion

A

Small, hard tumor developing on the eyelid, somewhat similar to a sebaceous cyst; also called meibomian cyst

51
Q

conjunctivitis

A

Inflammation of the conjunctiva and inner eyelids with vascular congestion; also called pinkeye

52
Q

drusen

A

Small yellowish deposits composed of retinal pigment cells that develop under the retina and are associated with an increased risk of developing age-related macular degeneration

53
Q

ectropion

A

Eversion, or outward turning, of the edge of the lower eyelid, causing it to pull away from the eye, generally associated with aging and weakness of the small muscles around the eyelid

54
Q

Swelling and hyperemia of the optic disc, usually associated with increased intracranial pressure; also called choked disc

61
Q

photophobia

A

Unusual intolerance of and sensitivity to light

62
Q

retinopathy

A

Any disorder of retinal blood vessels

63
Q

strabismus

A

Misalignment of the eyes so that they do not focus on the same object at the same time, sending two different images to the brain; also called heterotropia or tropia

64
Q

trachoma

A

Chronic, contagious form of conjunctivitis that typically leads to blindness

65
Q

anacusis

A

Complete deafness; also called anacusia

Q

conduction impairment

A

Blocking of sound waves as they pass through the external and middle ear (conduction pathway)

67
Q

labyrinthitis

A

Inflammation of the inner ear that usually results from an acute viral disease, such as mumps, measles, or influenza

68
Q

Ménière disease

A

Increased fluid pressure of the endolymphatic system that leads to progressive loss of hearing; also called endolymphatic/labyrinthine hydrops

69
Q

noise-induced hearing loss

A

Condition caused by the destruction of hair cells, the organs responsible for hearing, as a result of sounds that are “too long, too loud, or too close

70
Q

otitis externa

A

Infection of the external auditory canal

71
Q

presbyacusis
