Red Eye Flashcards
OU
Both eyes
OD
Right eye
OS
Left eye
Chemosis
Swelling, edema
If iris is pushed out
you get a crescent shadow - it’s glaucoma
Anatomy of eye outside in
Lids/lashes conj/sclera cornea anterior chamber iris lens
mucous membrane and blood supply
imm.sys response - allergies
Bulbar (over eye ball) conjunctiva
Fibrous CT, rigid
Sclera
check acuity, tonometry and slit lamp/pen light for patients presenting with
Red eye
Exam that measures intra occular pressure (IOP)
tonometry
Slit lamp exam measure
the depth of a lesion
- CHRONIC itch, burn
- worse in am
- no vis loss
- red, scales, debris, (meibomian dz)
Blepharitis
3 types of blepharitis
1 seborrheic
2 meibomian gland dysfx (white/yellow bumps on lids)
3 chalazion (m. gland blocked, chronic, outside)
seborrheic, meibomian dysfx, chalazion are
blepharitis
chronic
meibomian gland is blocked
huge bump outside
chalazion
vs stye, hordeoma is inside
no vision loss
due to aging
temporal twds nasal side
pingueculum
- thickening of bulbar conj
- grows slowly over outer cornea
- from nasal to temporal
- VISION loss/interferance
pterygium
acute pain, swelling
warm, red, tender
+/- vis loss
+/- systemic
Cellulitis
preseptal cellulitis
no vis loss
orbital cellulitis
eye muscles, decreased EOM
decrease in acuity
ER - IV ABs
Tx for cellulitis
Sys ABs for both types
- decrease in tears
- chronic itch, burn
- tired eyes, in PM
- +/- vision
Dry Eye
Tx for dry eye
artificial tear/oint top cyclosporin (if real bad)
acute
bilateral
watery discharge
-itch, burn, sore, mild to sev injection, URI, Preauricular LAN (lymphadenopathy)
vital conjunctivitis
acute
unilateral
thick exudate/mucopurulent discharge
burn, irritated, mod to severe injection, sticky eyelids,
bacterial conj.
chronic bilateral stringy/mucoid discharge chemosis - swelling itch, mild to mod injection
Allergic conj
tx for viral conj
tears/compress
vasoconstrictor (visine)
tx for bacterial conj
top ABs
+/- systemic ABs
test: gram stain/culture
cause for bacterial conj
Claumydia
tx for allergic conj
tears
antihistamines
acute, blood in eye, diffuse red
asymptomatic - trauma, cough, sneeze
no change in vision
Not ER
subconjuctival hemmorage
Tx: reassure
- SUBACUTE onset of foreign body sens
- PAIN
- deep bluish hue or
- lots of red bl vessels in ONE FOCAL AREA
- +/- nodule
Episcleritis/scleritis
(Pain is greater than conj)
(ONE focal area instead of whole conj)
TX: top/sys steroids, REFER
- ACUTE pain and f.body sens
- epiphora ?
- +/- vision loss
Corneal abrasion
Tx for corneal abrasion
lubricant
top AB - see back in 24-48 hrs
oral pain med
!!!!NEVER rx numbing/topical anesthetic drops!!!!
- ACUTE pain/burning
- red, pink, white color
- +/- vision decrease due to edema
- corneal abrasion
Chemical injury
Tx: irrigate ASAP!!!
refer!!!
top lubricants/abs
