[edit] Signs and symptoms
- Ocular and periorbital pain
- Photophobia
- Consensual photophobia (pain in affected eye when light is shone in unaffected eye)
- Blurred or cloudy vision
- White blood cells (leukocytes) in the anterior chamber (resulting in a grey or near-white appearing pupil) often called hypopyon [1]
- Flare
- Synechia or adhesion of iris to lens or cornea
[edit] Causes
People with ankylosing spondylitis and other HLA-B27 related disorders are prone to iritis, iridocyclitis, and other forms of uveal tract inflammation. Iritis is also found in those with rheumatoid arthritis, Behcet's disease, Crohn's disease, lupus, Reiter's disease, chronic psoriasis, psoriatic arthritis, sarcoidosis, scleroderma, and ulcerative colitis. Iritis is usually secondary to some other systemic condition, but can be the only apparent somatic symptom.
[edit] Complications
Cataract, glaucoma, corneal calcification, posterior uveitis, blindness
[edit] Treatment
- Steroid anti-inflammatory eye drops (such as prednisolone acetate)
- Dilating eye drops (to help prevent synechia and reduce photophobia)
- Pressure-reducing eye drops (such as brimonidine tartrate)
- Oral steroids (such as prednisone)
- Subconjunctival steroid injections
- Steroid-sparing agents such as methotrexate (for prolonged, chronic iritis)
