basal cell carcinoma

Answer 9

• papular appearance

- usually on lower lid + medial canthus

Question 10

chalazion

Answer 10

firm, nontender nodule on the eyelid

• fr infection of meibomian gland
• not painful unless inflamed

Question 11

hordeolum

Answer 11

aka STYE

• fr staph infection of hair follicles on lids
• swollen, red, painful

Question 12

entropion

Answer 12

inversion of lid + lash

• caused by muscle spasm of eyelid
• can cause corneal friction

Question 13

ectropion

Answer 13

eversion of eyelid

• caused by muscle weakness
• exposes the conjunctiva

Question 14

periorbital edema

Answer 14

swollen puffy lids

-occurs w crying, infection, trauma, systemic problems (kidney, hrt, allergy)

Question 15

exophthalmos

Answer 15

abnormal protrusion of eyes

-secondary to graves disease/hyperthyroid

Question 16

list of abnormalities of the eye

Answer 16

• conjunctivitis
• iritis
• subconjunctival hemorrhage
• pterygium
• hyphema
• acute glaucoma
• cataract
• pingueculae

Question 17

conjunctivitis

Answer 17

aka pink eye

• infection of the conjunctiva
• caused by bacteria, virus, or chem exposure

Question 18

iritis

Answer 18

• serious disorder
• redness around iris + cornea
• decr vision
• deep, aching pain
• pupil often irregular

Question 19

subconjunctival hemorrhage

Answer 19

• ruptured blood causes pooling

- caused by trauma, anticoag therapy, HTN, elevatoud venous pressure

Question 20

pterygium

Answer 20

noncancerous growth in conjunctiva

-may extend to sclera or cornea

Question 21

hyphema

Answer 21

collection of blood in anterior chamber of eye

• commonly caused by blunt trauma
• cause: eye surgery, blood vessel abnormality, medical problem, cancer

Question 22

acute glaucoma

Answer 22

sudden incr in intraocular pressure

• fr blocked flow of fluid fr anterior chamber
• pupil is oval shaped + dilated
• cornea is coudy w redness around
• pain onset is sudden w halos + decr vision

Question 23

cataract

Answer 23

opacity in lens

-usually occurs later in life

Question 24

pingueculae

Answer 24

yellowish nodules that are thickened in areas of bulbar conjunctiva
-caused by prolonged exposure to sun, wind, dust

Question 25

types of fundus abnormalities

Answer 25

- diabetic retinopathy - HTN retinopathy - age-related macular degeneration [ARMD]

Question 26

diabetic retinopathy

Answer 26

-microaneurysn, hemorrhage, macular edema, or retinal exudates

Question 27

HTN retinopathy

Answer 27

-flame hemorrhage, icking of vessels, "cotton wool" spots fr fiber infarction

Question 28

age-related macular degeneration [ARMD]

Answer 28

gradual loss of central vision | -periph vision remains

Question 29

types of impaired pupillary responses

Answer 29

- adie's pupil - argyll robertson pupil - anisocoria - CN 3 damage - horner syndrome - mydriasis - monocular blindness - miosis

Question 30

adie's pupil

Answer 30

aka tonic pupil - sluggish pupillary response - can be uni or bilateral - due to damage to parasymph nerves

Question 31

argyll robertson pupil

Answer 31

small, irregular pupils that exists bilaterally + nonreactive to light -occurs w CNS disorders such as tumor, syphilis, + narcotic use

Question 32

anisocoria

Answer 32

unequal pupillary size - may be normal - may be due to CNS disease

Question 33

CN 3 damage

Answer 33

- unilaterally dilates pupil - no rxn to light - ptosis

Question 34

horner syndrome

Answer 34

- blockage of symp nerve stimulation - unilateral small regular pupil that is nonreactive to light - may be ptosis + anhidrosis

Question 35

mydriasis

Answer 35

fixed dilated pupils | -may occur w symp nerve stim, glaucoma, CNS damage, deep anesthesia

Question 36

monocular blindness

Answer 36

results in direct + consensual response to light directed in normal eye + absence of response in either eye when light is directed in the blind eye

Question 37

miosis

Answer 37

fixed constricted pupil | -can be due to narcotics, damage to pons, or glaucoma Tx

Question 38

myopia

Answer 38

nearsighted - generally inherited - occurs when eye is longer than norm - light rays focus in FRONT of the retina

Question 39

hyperopia

Answer 39

farsighted - inherited condition - eye is shorter than norm - light rays focus BEHIND the retina

Question 40

astigmatism

Answer 40

often familial condition - refraction of light is spread over a wide area rather than on a distinct point of the retina - vision may be blurred or doubled

Question 41

presbyopia

Answer 41

age-related condition in which the lens of eye loses the ability to accommodate

Question 46

exophoria

Answer 46

outward turning of eye

Question 47

Answer 47

w phoria, deviation is a tendency but eye functions normally w tropia, it is assoc w strabismus
