A

Otitis media

72
Q

Achromatopsia

A

Congenital deficiency in color perception also called colorblindness

73
Q

Astigmatism

A

Defective curvature of the cornea and lens which causes light rays to focus unevenly over the retina rather than being focused on the single point resulting in a distorted image

74
Q

Cataract

A

Degenerative disease in which lens of the eye becomes progressively cloudy causing decreased vision

75
Q

Diabetic retinopathy

A

Retinal damage marked by aneurysmal dilation and bleeding of blood vessels or the formation of new blood vessels causing visual changes

76
Q

Glaucoma

A

Condition in which aqueous humor fails to drain properly and accumulates in the anterior chamber of causing elevation intraocular pressure (IOP)

77
Q

Open angle

A

Most common form of glaucoma results from degenerative changes that causes congestion and reduced flow of humor through the canal of schlemm

78
Q

Closed-angle

A

Type of glaucoma caused by an Anatomically narrow angle between Iris and the cornea which prevents outflow of aqueous humor from the eye into the lymphatic system causing a sudden increase in IOP

79
Q

Hordeolum

A

Small, purulent inflammatory infection of a sebaceous gland of the eye, called a sty

80
Q

Macular degeneration

A

Breakdown of the tissues in the macula resulting in loss of central vision

81
Q

Retinal detachment

A

Separation of the retina from the choroid which disrupts vision and results in blindness if not repaired

82
Q

Strabismus

A

Muscular eye disorder in which the eyes turn from the normal position so they deviate in different directions

83
Q

Esotropia

A

Strabismus in which there is deviation of the visual axis of one eye towards that of the other eyes resulting in diplopia also called cross eyed and convergent strabismus

84
Q

Exotropia

A

Strabismus in which there is deviation of the visual axis of one eye away from that of the other eyes resulting in diplopia also called wall-eyed and divergent strabismus

85
Q

86
Q

Anacusis

A

90
Q

Suppurative

A

Inflammation of the middle ear with pus formation

A

Impairment of hearing that results from the aging process

93
Q

A

Ringing or tinkling noise hears constantly or intermittently in one or both ears, even in quiet environment

94
Q

Vertigo

A

Sensation of moving around in space or a feeling of dizziness or spinning

95
Q

Tonometry

A

Procedure used to detect glaucoma that measures intraocluar pressure by determining the resistance of the eyeball to indentation by an applied force

96
Q

100
Q
