==Background==
*Classically blunt [[ocular Trauma|trauma]]: contusion and spasm of ciliary body and iris
*May occur in any traumatic injury<ref>Augsburger JJ, Corrêa ZM. Chapter 19. Ophthalmic Trauma. In: Riordan-Eva P, Cunningham, Jr. ET, eds. Vaughan &amp;amp;amp;amp;amp;amp; Asbury's General Ophthalmology. 18th ed. New York, NY: McGraw-Hill; 2011:371-382.</ref>
*90% of uveitis is iritis, and traumatic iritis accounts for 20% of iritis<ref>Gutteridge IF, Hall AJ. Acute anterior uveitis in primary care. Clinical and Experimental Optometry. 2007. 90(2):70-82.</ref>

==Clinical Features==
*Often delayed presentation after traumatic event, typically within 3 days of blunt [[ocular Trauma|trauma]]
*[[Eye pain]], especially if not relieved by topical anesthetic<ref>Reidy JJ. Section 08: External Disease and Cornea. Basic and Clinical Science Course. San Francisco, CA: American Academy of Ophthalmology; 2012: 363.</ref>
Symptoms 
*[[blurred vision|Blurry vision]] in affected eye
*Photophobia
*[[Floaters]]
*Tearing
*Perilimbal conjunctival injection, ciliary flush 
*[[Vision loss|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<ref>Bartley GB, Liesegang TJ. Essentials of Ophthalmology. Philadelphia, PA: JB Lippincott Company; 1992:156-157.</ref>
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<ref>Trevor-Roper PD, Curran PV. The Eye and Its Disorders. Boston, MA: Blackwell Scientific Publications; 1984:489-507.</ref>

==Differential Diagnosis==
{{Unilateral red eye DDX}}
{{Acute vision loss noninflamed DDX}}

==Evaluation==
*Clinical diagnosis

==Management==
#PO [[analgesia]]
#[[Cycloplegic]]s paralyze the ciliary body resulting in a nonreactive and dilated pupil, preventing synechiae, progression of flare, ciliary spasm pain<ref>Alexander KL, Dul MW, Lalle PA, Magnus DE. Onofrey B. Optometric Clinical Practice Guideline: Care of the Patient with Anterior Uveitis. St. Louis, MO: American Optometric Association; 1994:3-29.</ref>
##[[Homatropine]] 5% BID-TID
##[[Cyclopentolate]] 2% TID
##[[Scopolamine]] 0.25% BID
#[[Corticosteroids#Ophthalmic Steroids|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
