83
Q

lacrimal

A

84
Q

macular degeneration

A

Macular degeneration, or age-related macular degeneration (AMD), is a leading cause of vision loss in Americans age 55 and older. It causes severe loss of central vision, but peripheral vision is retained. AMD blurs the sharp central vision one needs for straight-ahead activities such as reading, sewing, and driving. AMD causes no pain.

A

Pertaining to an agent that causes the pupil to contract

86
Q

mydriatic

A

Pertaining to an agent that causes the pupil to dilate

87
Q

myopia

A

vision defect in which parallel rays come to a focus in front of the retina; nearsightedness.

88
Q

nyctalopia

A

Condition in which the individual has difficulty seeing at night; night blindness

89
Q

nystagmus

A

Involuntary, constant, rhythmic movement of the eyeball

90

96
Q

optician

A

One who specializes in making optical products and accessories, such as eyeglasses. This person is not a physician.

97

98
Q

orthoptics

A

Study and treatment of defective binocular vision resulting from defects in ocular musculature; also a technique of eye exercises for correcting defective binocular vision

99
Q

phacoemulsification

A

Process of using ultrasound to disintegrate a cataract by inserting a needle through a small incision and aspirating the disintegrated cataract.

100
Q

phacolysis

A

Surgical destruction and removal of the crystalline lens in the treatment of a cataract

101
Q

photocoagulation

A

Process of altering proteins in tissue by the use of light energy such as the laser beam; used to treat retinal detachment, retinal bleeding, intraocular tumors, and/or macular degeneration (wet)

102
Q

photophobia

Q

presbyopia

A

Vision defect in which parallel rays come to a focus beyond the retina; occurs normally with aging; also called hyperopia (farsightedness)

104
Q

pupillary

A

pertaining to the pupil

107
Q

retinitis

A

inflammation of the retina

108
Q

retinitis pigmentosa

A

Chronic progressive disease marked by bilateral primary degeneration of the retina beginning in childhood and leading to blindness by middle age. Night blindness and a reduced field of vision are early clinical signs of this disease.

109
Q

retinoblastoma

A

Malignant tumor arising from the germ cell of the retina

110
Q

retinopathy

A

Any disease of the retina. In the United States, diabetic retinopathy is the leading cause of new blindness in people age 20–74

111
Q

retrolental fibroplasia

A

Disease of the retinal vessels present in premature newborns; can be caused by excessive use of oxygen in the incubator; can cause retinal detachment and blindness

112
Q

scleritis

A

Inflammation of the sclera (white of the eye)

113
Q

strabismus
