Differential Diagnosis for Traumatic Iritis
Single Most Likely Diagnosis
- Traumatic iritis: This is the most likely diagnosis given the context of the question, as traumatic iritis is a common complication of ocular trauma, characterized by inflammation of the iris following an injury.
Other Likely Diagnoses
- Traumatic uveitis: This condition involves inflammation of the uvea, which includes the iris, and can occur after eye trauma.
- Hyphema: Blood in the anterior chamber of the eye, often resulting from trauma, which can lead to or be associated with iritis.
- Lens dislocation or subluxation: Trauma can cause the lens to become dislocated, leading to inflammation and potentially iritis.
- Vitreous hemorrhage: Bleeding into the vitreous humor, the gel-like substance inside the eye, which can be a result of trauma and may lead to secondary complications like iritis.
Do Not Miss Diagnoses
- Endophthalmitis: A severe, potentially sight-threatening infection within the eye that can occur after trauma. Although less common, missing this diagnosis could lead to severe consequences.
- Retinal detachment: Trauma can cause the retina to detach from the back of the eye, a condition that requires prompt treatment to preserve vision.
- Siderosis bulbi: If the trauma involves a metallic foreign body, especially iron, it can lead to siderosis bulbi, a condition where iron deposits in the eye cause damage and potentially severe vision loss.
- Sympathetic ophthalmia: A rare, bilateral granulomatous uveitis that can occur after penetrating eye injury, which, although rare, has significant implications for vision in both the injured and the uninjured eye.
Rare Diagnoses
- Phacolytic glaucoma: A condition where lens material leaks into the anterior chamber, causing an inflammatory response and increased intraocular pressure.
- Uveitic glaucoma: Glaucoma secondary to uveitis, which can be a complication of traumatic iritis.
- Traumatic cataract: Cataract formation as a result of eye trauma, which may not directly cause iritis but can be a related complication.
- Choroidal rupture: A break in the choroid, a layer of blood vessels between the sclera and retina, which can occur from blunt trauma and may lead to secondary complications.
