Retrobulbar hemorrhage
From WikEM
(Redirected from Orbital Hematoma)
Contents
Background
- Also known as retrobulbar hematoma
- Most often due to blunt orbital trauma
- Can also be secondary to spontaneous bleeding[1]
- Can cause loss of vision within 60-120 min due to abrupt increase in intraocular pressure → orbital compartment syndrome (OCS)
Clinical Features
- Pain
- Proptosis
- Decreased visual acuity
- Elevated IOP
- (Do not perform tonometry if globe rupture is suspected)
Differential Diagnosis
Maxillofacial Trauma
- Le Fort fractures
- Skull fracture (peds)
- Auricular hematoma
- Nasal fracture
- Zygomatic arch fracture
- Zygomaticomaxillary (tripod) fracture
- Dental trauma
- Mandible fracture
Orbital trauma
Acute
- Ruptured Globe^
- Corneal Abrasion
- Ocular foreign body
- Conjunctival laceration
- Caustic Keratoconjunctivitis^^
- Subconjunctival hemorrhage
- Traumatic iritis
- Traumatic hyphema
- Retinal detachment
- Retrobulbar hemorrhage/hematoma
- Traumatic mydriasis
- Orbital fracture
- Frontal sinus fracture
- Naso-ethmoid fracture
- Inferior orbial wall fracture
- Medial orbital wall fracture
Subacute/Delayed
Periorbital swelling
Proptosis
- Normal IOP
- Orbital cellulitis
- Orbital pseudotumor
- Orbital tumor
- Increased IOP
- Retrobulbar abscess
- Retrobulbar emphysema
- Retrobulbar hemorrhage
- Orbital tumor
No proptosis
- Periorbital cellulitis/erysipelas
- Dacryocystitis (lacrimal duct)
- Dacryocele/Dacryocystocele
- Dacryostenosis
- Dacryoadenitis (lacrimal gland)
- Allergic reaction
- Nephrotic Syndrome (pediatrics)
Lid Complications
- Blepharitis (crusts)
- Chalazion (meibomian gland)
- Stye (hordeolum) (eyelash folicle)
Other
- Subperiosteal abscess
- Orbital abscess
- Cavernous sinus thrombosis
- Conjunctivitis
- Contact dermatitis
- Herpes zoster
- Herpes simplex
- Sarcoidosis
- Granulomatosis with polyangiitis
Evaluation
- CT Orbit
- Ocular ultrasound[2][3][4]
- Dx of retrobulbar pathology via ultrasound is technically difficult, has not been validated in the clinical setting and false-negatives have been reported[1] - therefore, CT should remain the standard diagnostic tool for suspected retrobulbar pathology.
Management
- Consider lateral canthotomy and cantholysis, if indicated
- Emergent ophthalmology consultation
- Consider medical mangement in conjunction with cantholysis
- 20% mannitol 2 g/kg IV
- methylprednisolone, 250mg IV or hydrocortisone 100mg IV
- acetazolamide, 250 to 500mg IV
Disposition
- Admit
