Traumatic iritis
(Redirected from Traumatic Iritis)
Background
- Classically blunt trauma: contusion and spasm of ciliary body and iris
- May occur in any traumatic injury[1]
- 90% of uveitis is iritis, and traumatic iritis accounts for 20% of iritis[2]
Clinical Features
- Often delayed presentation after traumatic event, typically within 3 days of blunt trauma
- Eye pain, especially if not relieved by topical anesthetic[3]
Symptoms
- Blurry vision in affected eye
- Photophobia
- Floaters
- Tearing
- Perilimbal conjunctival injection, ciliary flush
- Decreased visual acuity
- Sluggish pupil affected eye
- Hallmark findings of consensual photophobia and “cell and flare” (anterior chamber) on slit limp examination
- “Cell:” individual cells floating in the anterior chamber (look like dust specks)
- “Flare:" protein floating in the anterior chamber from inflamed blood vessels. (smoke)
- Hypopyon (severe cases): leukocytic exudate in anterior chamber
- May deposit onto corneal endothelium as keratic precipitates[4]
Complications:
- Synechiae formation
- 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[5]
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
Evaluation
- 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[6]
- Homatropine 5% BID-TID
- Cyclopentolate 2% TID
- Scopolamine 0.25% BID
- Topical 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, but 5-7 days may be acceptable on a case by case basis
