Flashcards in The eye Deck (56):
1

Limbus

border between cornea and sclera lower lid margin

2

Meibomian gland

lubricates the eyelid

3

conjunctiva

protective membrane that covers the exposed part of the eye

4

palpebral conjuctiva

lines the eyelid

5

bublar conjunctiva

overlays the eyeball with the white sclera showing through

6

lacrimal apparatus

contant irrigation

7

EOMS are intervated by CN

3,4,5

8

CN III (oculomotor)

Superior, inferior, medial rectus oblique muscles, and medial and inferior oblique muscles

9

CN IV (trochlear)

Supervisor and oblique muscles

10

CN VI (abducens)

Lateral rectus muscle (abducts eye)

11

anterior chamber

contains the aqueous humor (pressure and refactory medium)

12

Optic Disc

Retinal fibers converge to form the head of the optic nerve

13

physiologic cup

yellow central depression (1/2 of disc)

14

Fundus

internal surface of retina central background

15

macula

temporal side, receives and transduces light, avacuscular and is the area of central vision

16

floaters

common with myopia, presopia, and aging

17

retinal detachment

sudden floaters, shade or cobwebs

18

halos

acute narrow angle glaucoma

19

scotomas

blind spots in visual fields, retinal tears

20

night blindness

optic atrophy, glaucoma, vitamin A deficiency

21

photophobia

intolerance to light

22

strabismus

deviation of the axis of the eye, all the time or due to fatigue, muscular or neuro

23

children with strabismus

affected eye does not conduct impulse, blindness due to non use

24

amblyopia

muscles, non-supportive, eyes drift and vision decreases, eye is normal

25

diplopia

double vision

26

hemianopia

blindness in half the visual field due to CVA

27

lacrimation

flow of tears

28

epiphoria

excessive tearing (due to obstruction or irritants)

29

myopia

nearsighted ``

30

hyperopia

farsighted

31

presbyopia

aging poor near vision

32

astigmatism

unequal light refraction

33

anisometropia

refractive error of both eyes

34

hirshberg tests

corneal light reflex
esotropia- inward
exotropia- outward
hypertropia- downward

35

cover test

assess eyes individually

36

nystagmus

fine osculating movement (extreme lateral normal), horizontal, vertical, rotational (if congenital- vision may be normal)

37

blepharitis

scaling seborrhea

38

ptosis

drooping upper lid

39

periorbital edema

infection, renal failure, CHF, allergy, hypothyroid

40

exophthalmos

protruding eyes, white sclera seen above and below the eye

41

enophthalmos

sunken eye

42

ectropian

lid rolls out

43

entropian

lid rolls in

44

sclera icterus

yellowing with jaundice

45

macular degeneration

leads to blindness

46

sclera blue

thinning due to aging

47

puncta

redness, swelling, tender, due to a blocked tear duct

48

5% nl solution with unequal pupils

49

chalazion

meibomian infection, usually chronic

50

keratoconjuctivitis sicca

dry eyes

51

hyphema

trauma, blood pooling in the eye under the cornea

52

yellow plaquing in the eye associated with hyperlipademia

53

subconjunctival hemorrhage

total red eye, no visual changes, coughing sneezing, reassurance, no tx, compresses

54

pterygium

triangular opaque wing of bulbar conjuctiva grows toward cornea

55

patients with systemic illnesses that affect vision need to see an ophthalmologist yearly

diabetes
hypertension
macular degeneration

56

Ophthalmoscope

cup to disc ratio:
