16
Q

Presbyopia

A

Decrease in power of accommodation that occurs with aging
(because the lens loses elasticity becoming hard and glasslike)

17
Q

Glaucoma

A

A group of eye diseases characterized by increased intraocular pressure, an optic nerve neuropathy

18
Q

cataract

A

Opacity of the lens of the eye, a clouding of the crystalline lens
from clumping of proteins, that develops slowly with aging and
gradually obstructs vision

19
Q

Cranial Nerve III (Oculomotor Nerve)

A

Causes constriction of the pupil by stimulating parasympathetic
branch and is the motor efferent path of the subcortical reflex
arc

20
Q

Cranial Nerve II (Optic Nerve)

A

Is the sensory afferent path of the subcortical reflex arc

21
Q

Cranial Nerves III (Oculomotor
Nerve), IV (Trochlear Nerve), VI
(Abducens Nerve)

A

Stimulates extraocular muscles to give the eye both straight and
rotary movement

22
Q

Corneal reflex

A

Contact with a wisp of cotton stimulates a blink in both eyes (CN V)carries afferent sensation and CN VII carries efferent message for
blink)

23
Q

Exophthalmos

A

Protruding eyeballs

24
Q

Enophthalmos

A

Sunken eyeballs

25
Q

Entropion

A
