Red eye and Emergencies Flashcards
Red-eye etiologies:
DUI IT!
D - Dry eye
U - Uveitis
I - IOP (above 21, 30-40 can be asymptomatic/vision loss with no red-eye)
I - Infections
T - Trauma (never put a pressure bandage)
Closed or narrow-angle glaucoma symptoms:
HyPHeN
H - Halos and blurry vision. y P - Pain H - Headache e N- N/V
Closed or narrow-angle glaucoma signs:
PI! CCAFA!!!
P - Pupil
I - IOP
C - Ciliary injection C - Cornea opaque A - Angle closed (Gonioscope) F - Flare A -Ant chamber is shallow
Glaucoma drugs - drugs that dec aqueous humor synthesis
B - beta bolckers (Timolol, betaxolol,carteolol)
A - alfa agonists (Epinephrine-a1, apraclonidine, brimonidine -a2)
D - Diuretics (Acetazolamide)
via vasoconstriction (Epinephrine)
via inhibition of carbonic anhydrase (Acetazolamide)
Glaucoma drugs - drugs that inc outflow of aqueous humor
Prostaglandins - uveoscleraI pathway (Bimatoprost, latanoprost -PGF2a)
Cholinomimetics, M3 - contraction of the ciliary muscle and opening of the trabecular meshwork
Cholinomimetics-Direct: pilocarpine, carbachol
Cholinomimetics-indirect: physostigmine, echothiophate
Definitive closed or narrow-angle glaucoma treatment:
Peripheral Iridotomy (Slit-lamp procedure if acute, Surgical if chronic- tough Iris)
Findings in Allergic\Viral\Bacterial conjunctivitis:
Allergic: Follicles - Papule
Viral: Follicles
Bacterial: Papule
Secretion color in Allergic\Viral\Bacterial conjunctivitis:
Allergic: watery
Viral: yellow
Bacterial: green
Papules vs Follicles structure:
Papules - central vasculature
Follicles - peripheral vasculature

Steroidal treatment icrease _______
IOP
Corneal Dendrites indicate______
Primary Herpes infection - Follicular Keratoconjunctivitis
Pseudo-Dendrites indicate______
Fungal infections
RF for HSV infection of the cornea:
Sweet TIC
Sweet - DM
T - Trauma
I - Immunodeficiency
C -Contact lens
Corneal Dendrites can be visualized with____(2)____.
Fluorescein or Rose-bengal
Follicular Keratoconjunctivitis treatment:
AAA:
A - Acyclovir 3% (local)
A - Acyclovir (systemic- for recurrent infection)
A - Antibiotics for superinfection coverage
NO Steroids! Only after the virus is gone and the patient is still in pain along with antiviral coverage and very carefully!
Stromal herpes treatment:
SALT with Plegia:
S - Steroids (at the beginning - we worry about immune system activation)
A - Acyclovir (local and systemic)
L - Lubrication
T - transplant (for optic axis)
C - Cycloplegics (Atropine/cyclopentolate ) for pain
Signs and symptoms of Herpes Zoster ophthalmicus:
Hutchinson DISCO is PG
Hutchinson - nose lesion (nasociliary nerve)
D - dendritic keratitis I - iridocyclitis S - scleritis or episcleritis C - chorioretinitis O - Optic neuropathy
P - paralisis of mucsles
G - Glaucoma
Herpes Zoster ophthalmicus treatment:
ASS!
Analgesics
Systemic Acyclovir
Steroids
