eye OD OS OU OD=R OS=L OU= both
Hyperopia Farsightedness; difficulty seeing close objects.
myopia nearsightedness
astigmatism imperfectly shaped cornea affects light focus
presbyopia impaired vision as a result of aging, 40+
hemianopia blindness in one-half of the visual field
Bitemporal hemianopsia loss of both temporal visual fields, lesion of optic
chaism
,homonymous hemianopsia loss of half of the field of view on the same side in
both eyes
homonymous quadrantanopia loss of one quarter of each visual field
Near reflex constriction of pupil that occurs with accommodation
of the lens in near vision. eyes will converge when
near
entropion inward turning of the rim of the eyelid, cause eye
abrasion
ectropion outward turning of the rim of the eyelid
chalazion a nodule or cyst, usually on the upper eyelid, caused
by obstruction in a sebaceous gland
Chalazion treatment warm compress
hordeolum stye usually staph
Xanthelasma soft, raised yellow plaques occurring on the skin at
the inner corners of the eyes, signals lipid disorder
blepharitis chronic eyelid inflammation, associated with
seborrheic dermatitis
subconjunctival hemorrhage resolves 1-2 wks, spontaneous, HTN, or trauma
pterygium thin fibrovascular tissue growing into the cornea from
the conjunctiva, usually caused from sun exposure or
dry eyes
, arcus senilis White ring around the cornea in older adults. 40+ if
younger consider hypercholesterolemia
Bacterial conjunctivitis pink eye, yellow discharge, red conjunctiva, eyes
glued shut in the morning, sudden onset, normal
vision, gritty pain, clear cornia, normal pupil, purulent
d/c, self limiting
acute iritis Don't mistake this for conjunctivitis, sx: Eye pain,
photophobia, blurry vision, redness, sluggish irregular
pupils, watery d/c
narrow angle glaucoma sudden increase in intraocular pressure when
drainage of the aqueous humor is blocked, rapid
vision loss, severe pain, vomiting, steamy cornea,
dilated oval non reactive pupil
corneal abrasion an injury, such as a scratch or irritation, to the outer
layers of the cornea, exquisite pain, irregular light
reflex
optic disc Region at the back of the eye where the optic nerve
meets the retina. It is the blind spot of the eye
because it contains only nerve fibers, no rods or
cones, and is thus insensitive to light. round with sharp
margins normal
optic cup the depression in the center of the optic disc, 1/3 the
size of the disc, larger with glaucoma and increased
intraocular pressure
Arteriovenous nicking Arteriovenous nicking (Compression of venule by
arteriole causing vein to bulging in either side; seen in
Hypertensive retinopathy)
