1

equipment you will need in an eye emergency

VA chart
proparacaine drops (topical anesthesia)
morgan lens
Nitrazine paper (pH)
Lid retractor
woods lamp
eye spud
floresceine paper
eye shield

2

Looks like a contact lens and attached to tubing and used for thorough eye irrigation

morgan lens

3

Tiny rotating abrasive that helps remove a metallic foreign body

eye spud

4

UV black lights; allows us to put fluroesceine stain in the eye

Woods Lamp

5

red eye ddx

i. Conjunctivitis
ii. Iritis
iii. Corneal abrasions/ulcerations
iv. Acute Angle Closure Glaucoma
v. Herpes infections

6

painless loss of vision

i. Central retinal artery occlusion
ii. Retinal detachment

7

trauma associated with the eye

i. Burns
ii. Blunt trauma
iii. Penetrating trauma
iv. Hyphema

8

hx and ROS from pt

onset: sudden or gradual
pain
VA
photophobia
trauma
associated sxs: headache, vertigo, neuro

9

general PE for eye complaint

general
VA-
pupils-symmetry, reactivity to light, pupillary reflex
fluorescein stain
intraocular pressure testing
slit lamp exam
signs of trauma

10

VA testing should be done how

when would you not do a VA test first

with glasses, one eye at a time

Should be done first on all patients except those with chemical exposures or suspected globe rupture

11

Signs of major trauma

Obvious laceration
Distorted pupil
Proptosis

12

Differential for decreased visual acuity

1. Refractive error (pin hole)
2. Penetrating foreign body
3. Iritis
4. Acute Angle Closure glaucoma
5. Central retinal artery occlusion
6. Blunt or penetrating trauma
7. Dislocated lens
8. Retinal detachment
9. Optic neuritis

13

Iritis

assoc w/ photophobia)

14

When is an eye problem not really an eye problem (3 scenarios)

subarachnoid hemorrhage (thunder clap)
stroke
GCA

15

eye issues associated with SAH

pain/photophobia))

16

eye issues associated with stroke

i. Diplopia
ii. Loss of vision

17

eye issues associated with GCA

late

18

MC identifiable source of optic neuritis

and what are the different presentations

MS

Clinical presentation depends on whether inflammation involves the optic disc (papillitis) or the part of the optic nerve behind the eyeball (retrobulbar neuritis).

19

what part of the eye has
Cones and rods transform light into visual signals, which are projected to the brain via the optic nerve.

(NIL)

reitna

20

what is glaucoma (NIL)

A group of eye diseases characterized by progressive optic neuropathy that results in a specific pattern of irreversible optic disc changes and visual field defects.

In the US, glaucoma is the second leading cause of blindness in adults (second to macular degeneration)

21

open and vs closed angle

open angle: generally bilateral, progressive loss of optic nerve fibers with open chamber angles (often with increased IOP), not caused by another systemic or local condition

closed angle: sudden and sharp increase in intraocular pressure caused by an obstruction of aqueous outflow (most commonly as a result of an occlusion of the chamber angle)

22

red flags

Sudden onset of pain or vision change
Decreased visual acuity
Photophobia
Limbic/ciliary flush (keratitis)
Abnormal pupil size, shape or response
Visible opacity on cornea

23

who do you want to bring to the treatment area emergently

 Chemical burns – Irrigate
 Sudden, painless vision loss: Notify MD
 Sudden onset severe pain,decreased vision
 Consider risk of CVA, SAH
 May use 1-2 gtts of proparacaine for FB sensation.
 Globe rupture – metal eye shield

24

red painful eye think

Conjunctivitis/keratitis

Foreign Body/Abrasion

Corneal ulcer

Iritis/uveitis

Acute narrow angle glaucoma

25

conjunctivitis pertenant negatives

no change in vision
no photophobia
injection spares the edges of the iris
no limbic or ciliary flush that you see wiht more serious eye pathologies

26

pain culprits of conjunctivitis

adenovirus

27

conjunctivitis

Warm compresses, topical antibiotic if indicated

28

blepharitis is commonly associated with

Seborrheic dermatitis
Psoriasis
Acne rosacea
Bacterial
foliculitis

29

blepharitis tx

Warm compresses
Topical antibact ointment

30

a hordeolum is an infection of the

meibomian glands
