1

ciliary body connects anteriorly to the

iris

2

ciliary body connects posteriorly to

choroid

3

cornea continues as

sclera

4

Ciliary body the iris and the choroid are part of the

Uvea

5

Most inflammation in the eye stems from

Uvea

6

What gives you red eye

anterior segment pathology
infection
inflammation
irritation

7

Rare exception of red eye can be due to

acute angle closure glaucoma

8

Everything in the posterior segment of the eye is

PAINLESS

9

3 EXCEPTIONS to painless vision loss

- optic neuritis
- GCA
(optic nerve inflammation)

10

overactive meibomian glands can lead to

blepharitis
common in patients with rosacea

11

what can be used in a low dose to treat belpharitis?

Dox or Minocycline

12

If a meibomian gland gets blocked

internal stye vs external
dont need Abx

13

Blocked oil glands if acute it's called

Hordeolum = stye

14

External oil gland blockage

Hair follicle

15

Internal oil gland blockage

meibomian gland

16

Chronic oil gland blockage can lead to

chalazion

17

Orbital cellulitis is

an emergency - can blind patient
- compartment optic nerve compression

18

4 "NO"s in preseptal compared with orbital cellulitis

1) NO PROPtosis
2) no pain with EOM
3) NO limitation of EOM
4) NO optic disc edema
GLOBE IS WHITE
PERL pupils

19

PERL

pupils equal and reactive to light

20

Bacteria in preseptal vs orbital cellulitis

preseptal - usually from skin - staph, strep pnemo, H flu
orbital - usually from nose- Staph, strp pneumo, Beta hemolytic strep

21

2 bacteria that distinguish preseptal from orbital cellulitis

In pre septal includes H flu
In orbital includes hemolytic strep

22

In spontaneous subconjunctival hemorrhage

NO effect on vision
always self-limited
DONT stop anti-coag therapy

23

2 Key signs of bacterial conjunctivitis

PURULENT discharge
NO preauricular lymph nodeds

24

First thing that should come to mind with HYPERpurulent conjunctivitis

Nisseria gonorrhea -EMERGENCY
- can perforate cornea!
IV ceftriaxone

25

Classic Hx of viral conjunctivitis

starts in one eye, moves to other

26

Signs/symptoms viral conjunctivitis

- pre-auricular lymph node
- teary discharge, NO PUS
- ITCHY!
- pseudomembranes

27

treatment for viral conjunctivitis

symptoms relief, lubrication and cool compress

28

Post-infection with viral conjunctivitis can get

subepithelial infiltrates inside the cornea stroma

29

Allergic conjunctivitis

both eyes
seasonal
- itchy!

30

Giant papillary conjunctivitis is

in contact lens wearers
-

31

Both allergic and viral conjunctivitis - what type of discharge?

watery

32

Conjunctival reaction in viral vs allergic and bacterial conjunctivitis

In viral it's follicular! others papillary

33

Inflammation of superficial scleral vessels gives you

episcleritis vs scleritis (deep)

34

Scleritis

VERY painful!
- diffuse or sectoral
- think systemic problem - collagen vascular

35

Distinguish episcleritis from scleritis on exam

phenylephrine blanches vessels in episcleritis, not in scleritis

36

Difference between corneal abrasion vs ulcer

Ulcer - infection - white - blocks view of iris
- ulcer may have hypopyon

37

Corneal abrasion will appear ? on fluorescin exam

clear - it's a scratch

38

Corneal ulcers are common in

contact lens wearers

39

how do you treat corneal abrasion vs ulcer

prophylactic in abrasion
but q1h for ulcers - Fluoroquinilones

40

3 features of corneal ulcers - EMERGENCY

- WHITE opacity
- contact lens wearer
- possible hypopyon

41

DO NOT ALLOW PATIENTS TO USE

topical anesthetics

42

HSV leading to keratitis

- see a dendrite with end bulbs
treat with topical or oral antiviralss

43

SHOULD NOT prescribe what in HSV infection

STEROIDS!

44

If HSV zoster shows up near tip of nose and eye - how do you treat?

- treat SYSTEMIC antivirals for 1 week
- no topical!
- REFER if red, painful or blurred vision

45

What do the dendrites look like in Herpes simplex vs zoster

Simplex - dendrites
Zoster- pseudodendrites

46

Iritis can be caused by

Psoriatic Arthritis
- AS
- Crohn's
- idiopathic RA
- Sarcoid
- syphilis
-TB

47

Hypopyon is

a severe form of iritis

48

Iritis can cause

- posterior synechiae - adhere to lens
- glaucoma -

49

A red eye, with pain, photophobia, decreased vision, or limbal redness should

refer

50

Endophthalmitis is

inflammation of every internal layer of the eye inside the sclera
- usually infectious!

51

If a patient has a history of ocular surgery, and presents with a hypopyon,

endopthalmitis
-

52

Signs/symptoms of endophalmitis

- SEVERE pain
reduced vision
Hypopyon
Recent eye surgery

53

Treatment of endophalmitis

- Intravitreal Abx - topical +/- IV

54

Headache, nausea, vomiting, red eye, pain, blurred vision: signs of

acute angle closure glaucoma

55

On physical exam, AACG wil present as

Fixed mid-dilated pupil
