what diseases can a fever help differentiate

preseptal vs. orbital cellulitis
(orbital typically presents with temp > 102 degrees)

20

DDx for swelling/edema in red eye

-preseptal cellulitis

21

#1 cause of bilateral proptosis is

Grave's disease

22

what can vitiligo be associated with?

uveitis (some)

what can a port wine stain be associated with?

Sterge-Weber
(glaucoma angle closure associated)

24

what is it called when palpebral conj is stuck to bulbar conj? what can is be associated with?

called symblepheron
-can be associated with chemical burns, chronic inflammation, Steven's Johnson syndrome

25

indications for performing exophthalmometry

-proptosis
-Grave's
-Tumor

26

exophthalmometry norms for children

14.5 - 16 mm

27

exophthalmometry norms for caucasians

12 - 20 mm

28

exophthalmometry norms for African Americans

12 - 24 mm

29

exophthalmometry norms for Asians

12 - 18 mm

30

exophthalmometry measurements should be within ___ mm of each other

2 mm

31

if there is greater than a __ mm difference between the eyes on exophthalmometry, further investigation should be done

3 or greater

32

which exophthalmometry has a base number to record

Hertel

33

which exophthalmometry is transparent, faster, easiest, least expensive, but not as accurate

Luedde

34

demodex (parasite) "mites" in the lashes are called

folliculorum

35

demodex (parasite) "mites" in the meibomian glands are called

brevis

36

how does demodex "mites" survive and cause damage?

0eat epithelial cells at hair follicle
-microabrasions from claws lead to cylindrical dandruff at base of lashes
-inflammation due to chitin (extoskeleton)

37

treatment for demodex (mites)

-tea tree oil (needs to be mixed with something else since dangerous to cornea)
-Cilradex wipes (with tee tree oil)
-ointment to suffocate them
-warm compresses
-lid scrubs

38

describe the debridement-scaling technique

-remove devitalized tissue and debris from line of marx (LOM), area of contact between the lid margin and bulbar conj/cornea with lissamine green and spud tool

39

which one of the following tools is less risky at squeezing meibomian glands too hard and damaging them? (Mastrota paddle or tears meibomian expresser forcep)

Mastrota paddle less risky

40

what is meibography useful for?

to look at meibomian glands and to see atrophy or drop out

41

a diffuse beefy engorged vessels usually more prominent in the inferior 1/3 of the conj (especially the fornices) is descriptive of a:

bacterial

42

diffuse injection can be descriptive of

viral, scleritis, corneal ulcer, blepharoconjunctivitis, herpes simplex keratitis, herpes zoster keratitis, toxic conjunctivitis

43

very mild diffuse injection (chemosis is greater) is indicative of

allergic

44
