Sudden Loss of Vision
Central retinal artery occlusion
Central retinal vein occlusion
Retrobulbar neuritis
Amaurosis fugax
Retinal detachment
Central Retinal Artery Occlusion
Sudden monocular painless, complete
loss of vision
Fundoscopic exam: pale retina with
macular red spot
Central Retinal Artery Occlusion
Treatment
STAT opthy consult
Digital massage of the globe
Increase CO2 (arteriolar dilatation) –
carbonic anhydrase inhibitor (i.e.
acetazolamide)
Definitive treatment – paracentesis of the
anterior chamber
Central Retinal Vein Occlusion
Sudden monocular
painless, and near
complete loss of
vision
Fundoscopic exam:
chaotic, bloodstreaked retina
Stat ophthalmology
consult
Optic Neuritis
Progressive loss of
central vision
May be painful,
scotoma, flashing
lights
Peripheral vision
preserved
Associated with
multiple sclerosis in
25% of cases
Amaurosis Fugax
Fleeting painless loss of monocular vision
Due to minute emboli of the central retinal
artery
Consult neurology for TIA workup
Retinal Detachment
Painless
Prodromal floaters or
flashing lights, followed
by “lowering curtain”
Opthy consult
Red Eye
Acute angle closure glaucoma
Acute iritis
Conjunctivitis
Herpes simplex keratitis
Corneal ulceration
Chemical conjunctivitis
Corneal abrasions
Acute Angle Glaucoma
Sudden severe unilateral ocular pain
Decreased visual acuity
Precipitous increased IOP  blindness if
untreated
Symptoms: HA, nausea, blurred vision or
rainbow halos
Pupil dilatation is often precipitant event from
sympathomimetics, parasympatholytics, stress,
fatigue, darkness.
Acute Angle Glaucoma
Red eye
Nonreactive middilated pupil
Corneal edema
Shallow anterior
chamber
High intraocular
pressure (60-90)**
Hazy cornea
**Normal IOP <20
Glaucoma Treatment
Stat opthy consult for definitive treatment –
iridectomy
Timolol – beta blocker
Pilocarpine – parasympathomimetic
Acetazolamide – carbonic anhydrase inhibitor
Mannitol
50% glycerol – oral hyperosmotic – if patient
can tolerate PO – give in place of mannitol
Timolol Solution
Beta blocker
Decreases aqueous humor formation
0.5% solution – 1-2 drops at 10-15 min
intervals x 3, then 1 drop every 12 hours
Pilocarpine
Parasympathomimetic
Produces miosis
2% solution – 1 drop every 30 minutes
until the pupil constricts, then 1 drop every
6 hours
Side effects: bradycardia, hypotension,
sweating, tremors
Acetazolamide
Carbonic anhydrase inhibitor
Inhibits aqueous humor formation
500 mg IV every 12 hours or 500 mg PO
every 6 hours
Side effects: respiratory depression,
metabolic acidosis
Mannitol
Increases blood osmolality, creating a
gradient that draws water from the vitreous
cavity
20% 1-2 grams/kg IV over 30-60 minutes
Side effects: headache, confusion, CHF,
dehydration
Acute Iritis
Blurred vision, photophobia, ocular pain
Exam:
– Ciliary flush
– Anterior chamber cells and flare
– Constricted pupil
– Decreased visual acuity
– Lower IOP
– Consensual photophobia
Acute Iritis: Treatment
Cycloplegics
– i.e. Homatropine – dilates the eyes
Topical steroids
Close opthy follow up
Acute Iritis
Conjunctivitis
Nonpainful red eye
Bacterial, viral, or allergic
Herpes Simplex Keratitis
Red eye with foreign
body sensation
Dendritic fluorescein
uptake
Treatment: acyclovir
drops, cycloplegics
Steroids contraindicated
Opthy consult
Corneal Ulceration
Red, painful eye
Slit lamp
– White flocculent infiltrate of the cornea
– Hypopyon
Anterior chamber exudate
May lead to corneal destruction and
perforation
?Admit, IV antibiotics
Corneal Ulceration
Chemical Conjunctivitis
Alkali burn – absolute ocular emergency
– Liquefactive necrosis
– Immediate irrigation (pH 7-7.5)
– Opthy consult
– Only opthy emergency in which visual acuity
is not checked until after therapy has begun
Alkali Burns
Chemical Conjunctivitis
Acid burn
– Coagulative necrosis
– Immediate irrigation as above
– Opthy consult
Corneal Abrasions
Foreign body sensation and photophobia
Diagnose: fluorescein uptake with slit lamp exam
– rule out foreign body with lid eversion
Suspect foreign body if “ice rink sign” – fine
linear abrasions in upper 1/3 cornea
Rule out corneal ulceration
Do not use steroid drops –may be difficult to rule
out early HS keratitis
Treatment: antibiotic ointment/drops, analgesics
Prognosis is very good
Corneal Abrasion
Traumatic Eye Injuries
Corneal laceration
Perforated globe
Intraocular foreign body
Hyphema
Blow-out orbital fracture
Traumatic iritis or retinal detachment
Corneal Laceration
Tear shaped pupil – prolapse of the iris
Small black fragments representing iris
pigment may be seen and initially
mistaken for a foreign body
May not see the laceration itself
Treatment: metal shield, STAT opthy
consult for surgical repair
Corneal Laceration
Perforated Globe
Suspect if penetrating wound to the eyelid
Decreased visual acuity, soft globe (do not
palpate)
Fundoscopic exam may reveal vitreous
hemorrhage
Treatment: Metal shield, STAT opthy
consult for surgical repair
Intraocular Foreign Body
Patient often gives a history of striking
metal on metal
May be initially painless, but then patient
develops monocular pain and decreased
visual acuity
May not see the wound
Diagnosis: CT scan, ultrasound or x-ray of
the globe
Treatment: Opthy consult for surgical
removal
Orbital Foreign Body
Hyphema
Hemorrhage in the anterior
chamber
See blood/vitreous line in
inferior iris
Treatment

Bed rest
Head of bed elevation
Opthy consult
Steroids
Miotics
Blow-out Orbital Fracture
Blunt globe trauma (i.e. fist to eye)
transmits forces that lead to orbital floor
fracture
Inferior rectus muscle may prolapse
through the fracture
Pain and diplopia or loss of upward gaze,
enophthalmos (sunken eye), infraorbital
anesthesia
Treatment: OR if entrapment, opthy
consult
