Background

  • Classically blunt trauma: contusion and spasm of ciliary body and iris
  • May occur in any traumatic injury[1]
  • Iridocyclitis because both the iris and the underlying ciliary body are inflamed
  • Iritis
    • HLA-B27 antigenic marker also strongly linked to spondyloarthritis such as ankylosing spondylitis

Clinical Features

  • Often delayed presentation after traumatic event, typically 24-48 hrs
  • Eye pain, especially if not relieved by topical anesthetic[2]
  • Decreased visual acuity in affected eye
  • Photophobia (direct and consensual)
  • Sluggish pupil
  • Hypopyon (severe cases): leukocytic exudate in anterior chamber
  • Cell & flare (anterior chamber reaction)
    • “Cell:” individual cells floating in the anterior chamber (look like dust specks)
    • “Flare:" protein floating in the anterior chamber from inflamed blood vessels. (smoke)
    • May deposit onto corneal endothelium as keratic precipitates[3]
  • Vossius' ring on anterior lens capsule
    • Due to concussive force of posterior iris onto lens
    • Depositing pigment in the pattern of a miosed pupil onto anterior lens
  • IOP may be increased due to inflammation, damage to ciliary body, or circumferential synechial formation[4]

Differential Diagnosis

Unilateral red eye

^Emergent diagnoses ^^Critical diagnoses

Diagnosis

  • Clinical diagnosis

Management

  1. Cycloplegics (eg. Homatropine 5%, or cyclopentolate 2%, 3 times per day until ophthalmology follow-up): paralyzes the ciliary body resulting in a nonreactive, dilated pupil
  2. PO analgesia
  3. Steroids in consult with optho (rule out infection first)

Disposition

Follow up with optho in 24-48 hours
