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
- Nontraumatic
- Acute angle-closure glaucoma^
- Anterior uveitis
- Conjunctivitis
- Corneal erosion
- Corneal ulcer^
- Endophthalmitis^
- Episcleritis
- Herpes zoster ophthalmicus
- Inflamed pinguecula
- Inflamed pterygium
- Keratoconjunctivitis
- Keratoconus
- Nontraumatic iritis
- Scleritis^
- Subconjunctival hemorrhage
- Orbital trauma
- Caustic keratoconjunctivitis^^
- Corneal abrasion, Corneal laceration
- Conjunctival hemorrhage
- Conjunctival laceration
- Globe rupture^
- Hemorrhagic chemosis
- Lens dislocation
- Ocular foreign body
- Posterior vitreous detachment
- Retinal detachment
- Retrobulbar hemorrhage
- Traumatic hyphema
- Traumatic iritis
- Traumatic mydriasis
- Traumatic optic neuropathy
- Vitreous detachment
- Vitreous hemorrhage
- Ultraviolet keratitis
^Emergent diagnoses ^^Critical diagnoses
Acute Vision Loss (Noninflamed)
- Painful
- Arteritic anterior ischemic optic neuropathy
- Optic neuritis
- Temporal arteritis†
- Painless
- Amaurosis fugax
- Central retinal artery occlusion (CRAO)†
- Central retinal vein occlusion (CRVO)†
- High altitude retinopathy
- Open-angle glaucoma
- Posterior reversible encephalopathy syndrome (PRES)
- Retinal detachment†
- Stroke†
- Vitreous hemorrhage
- Traumatic optic neuropathy (although may have pain from the trauma)
†Emergent Diagnosis
Diagnosis
- Clinical diagnosis
Management
- PO analgesia
- Cycloplegics paralyze the ciliary body resulting in a nonreactive and dilated pupil, preventing synechiae, progression of flare, ciliary spasm pain[5]
- Homatropine 5% BID-TID
- Cyclopentolate 2% TID
- Scopolamine 0.25% BID
- Steroids in consult with optho
- Rule out infection first and avoid corneal epithelial defect
- Prednisolone acetate 0.5-1% QID
- If secondary glaucoma as complication, may use timolol 0.5% BID if no contraindication
Disposition
Follow up with optho in 24-48 hours
