Iridodialysis
Background
- Localized separation of the iris from the ciliary body
- Most commonly caused by blunt trauma to the eye[1]
- May also be caused by penetrating eye trauma or as an iatrogenic injury during ophthalmologic procedures
Iridodialysis
Differential Diagnosis
Orbital trauma
Acute
- Caustic keratoconjunctivitis^^
- Conjunctival laceration
- Corneal abrasion
- Globe rupture^
- Iridodialysis
- Ocular foreign body
- Orbital fracture
- Frontal sinus fracture
- Naso-ethmoid fracture
- Inferior orbial wall fracture
- Medial orbital wall fracture
- Retinal detachment
- Retrobulbar hemorrhage/hematoma
- Subconjunctival hemorrhage
- Traumatic hyphema
- Traumatic iritis
- Traumatic mydriasis
Subacute/Delayed
Evaluation
- Clinical diagnosis
Management
- Simple iridodialysis requires no specific ED treatment
- Small iridodialysis often managed conservatively - if large and/or symptomatic, generally requires surgical repair[1]
- If associated with hyphema, see hyphema management
Disposition
- Based on discussion with ophthalmology
