Flashcards in Monday week 11 Deck (47):
1

How can be applied to eyes

solutions- can see through, evaporates
gels - fat
ointments - more fat better contact tme
medicated contacts
collagen sheilds
injection

2

what types of eye meds

- anesthetic - opthane
- staining agents
- mydriatics - dialate
- cycloplegics - paralysis of accomination
- miotics

3

what should you do if anyone comes with eye complaint

always do a visual aquity exam, may need opthane anesthetic if necessary

4

down side of eye anesthesia, corneal abrasion

slows down eye epithelia healing** increase risk of infection ulcer

5

myriatics

dialte puple

6

cycloplegics

paralysis of accommodation

7

miotics

pupillary constriction

8

2 agents for eye exams

mydriatics - dilate
mytotics - pupil constriction

9

Fluroescein dye: orange

affixes to damage in eye, abrasion, infx, ulceraion then luminesence
- can stain contact lenses

10

light to use with fluroescein

Colbalt blue light

11

whaat infections can you see

- herpes keratitis
- herpes zoster

12

how is fluroescein dye appliec

imbeded pieces of paper, wet with salene then hold against lower lid in multiple

13

ocular steroids

herpes infection:
must be used with an anti viral and possibly anti bacterial

14

Etiologies of dry eye

- auto immune, lupus , sjogrens
- contact lense - most common***
- envirionment

15

what do OTC lubricants ususally have

Glycerin solutions

16

Cyclosporine/Restasis

anti rejection drug immune modulation
wetting agent for eyes

17

MOS cyclosporine

T cell inhibition diminished inflammation which allows tear production

18

Conjunctivitis

Pink eye
- allercic most common hear
- viral
- bacterial
- ultraviolet burns
- chemical toxins
- contact overuse

19

conjunctivits, sx

conjunctivitys is itchy, lid swelling and discharge, but no swelling over iris and pupil,

20

bacterial

pyogenic
stringy grey or yellowish discharge

21

Tetrahydrozoline/visine

ocular astringent, redness reliever

22

moa of tetrahyrozoling/visine

vasocontrictor

23

side effects of visine overuse

rebound redness vasodilation, local irritation

24

why zinc in visine

act as astringent to keep from watering .

25

Azelastine/optivar

ocular antihistamine - workse good, for allergic conjunctivitis

26

MOA of azelastine/optivar

antihistamine
- H1 receptor blocker

27

side effects of azelastine

local irritation, limited systemic absorption

28

visine

tetrahydrozoline- eye redness

29

optivar

azelastine - ocular antihistamine

30

Ketorolac/acular - MOA

cyclooxygenase inhibitor
non steroidal - eye discom

32

side effects ketorolac/Acular

slight increase risk of glaucoma

IV for systemic used, Ie herpes in eye

39

problem with glaucoma

damage optic nerve,
visual field loss,
leading to blindness

acute angle closure glaucoma

acute pain, injection to iris past limbus past pupil, this is very concering . medical emergency

41

chemosis

swelling of the schelera if the eye

42

how is glaucoma treated

- Beta blockers
- prostaglandins analogues to shrink pupil- more space to drain
