A number of connective tissue diseases cause inflammation of the uveal tract. (See also Overview of Uveitis Overview of Uveitis Uveitis is defined as inflammation of the uveal tract—the iris, ciliary body, and choroid.

The seronegative spondyloarthropathies Overview of Seronegative Spondyloarthropathies Seronegative spondyloarthropathies (seronegative spondyloarthritides) share certain clinical characteristics (eg, inflammatory back pain, uveitis, gastrointestinal symptoms, rashes).

Among the seronegative spondyloarthropathies, ocular inflammation is most common with ankylosing spondylitis Ankylosing Spondylitis Ankylosing spondylitis is the prototypical spondyloarthropathy and a systemic disorder characterized by inflammation of the axial skeleton, large peripheral joints, and digits; nocturnal back... read more but also occurs with reactive arthritis Reactive Arthritis Reactive arthritis is an acute spondyloarthropathy that often seems precipitated by an infection, usually genitourinary or gastrointestinal.

The arthritis is often asymmetric, and... read more . Uveitis is classically unilateral, but recurrences are common and active inflammation may alternate between eyes. Men are affected more commonly than women. Most patients, regardless of sex, are HLA-B27 positive.
Treatment requires a topical corticosteroid and a cycloplegic-mydriatic drug. Occasionally, periocular corticosteroids are required. Severe chronic cases may require noncorticosteroid immunosuppressive drugs (eg, methotrexate, mycophenolate mofetil).
Juvenile idiopathic arthritis (JIA)
JIA Juvenile Idiopathic Arthritis (JIA) Juvenile idiopathic arthritis is a group of rheumatic diseases that begins by age 16. Arthritis, fever, rash, adenopathy, splenomegaly, and iridocyclitis are typical of some forms. Diagnosis... read more , previously known as juvenile RA, characteristically causes chronic bilateral iridocyclitis in children, particularly those with the pauciarticular variety. Unlike most forms of anterior uveitis, however, JIA-associated uveitis tends not to cause pain, photophobia, and conjunctival injection but only blurring and miosis and is, therefore, often referred to as white iritis. It can be asymptomatic. JIA-associated uveitis is more common among girls. Because symptoms can be overlooked or absent, patients with JIA should be regularly screened.
Rheumatoid arthritis, in contrast, is not associated with isolated uveitis but can cause scleritis, which may cause secondary uveal tract inflammation.
Recurrent bouts of inflammation are best treated with a topical corticosteroid and a cycloplegic-mydriatic drug. Given the chronic nature of disease and risk of treatment-related cataract and glaucoma development, long-term control often requires use of a noncorticosteroid immunosuppressive drug (eg, methotrexate, mycophenolate mofetil).
Sarcoidosis Sarcoidosis Sarcoidosis is an inflammatory disorder resulting in noncaseating granulomas in one or more organs and tissues; etiology is unknown. The lungs and lymphatic system are most often affected, but... read more accounts for 10 to 20% of cases of uveitis, and about 25% of patients with sarcoidosis develop uveitis. Sarcoid uveitis is more common among patients of African descent and older patients.
Virtually any symptoms and signs of anterior, intermediate, posterior, or panuveitis can occur. Suggestive findings include conjunctival granulomas, large keratic precipitates on the corneal endothelium (so-called granulomatous or mutton fat precipitates), iris granulomas, and retinal vasculitis. Biopsy of suggestive lesions, which provides the most secure diagnosis, is usually done on the conjunctiva; it is rarely done on intraocular tissues because of the risk associated with the procedure.
Treatment usually involves topical, periocular, intraocular, or systemic corticosteroids, or a combination, along with a topical cycloplegic-mydriatic drug. Patients with moderate to severe inflammation or chronic disease may require a noncorticosteroid immunosuppressive drug (eg, methotrexate, mycophenolate mofetil).

Common manifestations include recurrent oral ulcers, ocular inflammation, genital ulcers, and... read more is rare in North America but is a fairly common cause of uveitis in the Middle East and Far East.
Typical findings include severe anterior uveitis with hypopyon, retinitis, retinal vasculitis, and optic disk inflammation. The clinical course is usually severe with multiple recurrences.
Diagnosis requires the presence of associated systemic manifestations, such as oral aphthous or genital ulcers; dermatitis, including erythema nodosum; thrombophlebitis; or epididymitis. Oral aphthae may be biopsied to show an occlusive vasculitis. There are no laboratory tests for Behçet disease, but it is associated with HLA-B51.
Treatment with local and systemic corticosteroids and a cycloplegic-mydriatic drug may alleviate acute exacerbations, but most patients eventually require systemic corticosteroids and a noncorticosteroid immunosuppressive drug to control the inflammation and avoid the serious complications of long-term corticosteroid treatment. Biologic agents such as interferons and tumor necrosis factor inhibitors have been effective in selected patients unresponsive to other therapies. Alkylating agents (eg, cyclosporine and chlorambucil) have induced remission in patients.
Vogt-Koyanagi-Harada (VKH) disease
Vogt-Koyanagi-Harada disease is an uncommon systemic disorder characterized by uveitis accompanied by cutaneous and neurologic abnormalities. VKH disease is particularly common among people of Asian, Asian Indian, American Indian, and Hispanic descent. Women in their 20s and 30s are affected more often than men. The etiology is unknown, although an autoimmune reaction directed against melanin-containing cells in the uveal tract, skin, inner ear, and meninges is strongly suspected.
Neurologic symptoms tend to occur early and include tinnitus, dysacusis (auditory agnosia), vertigo, headache, and meningismus. Cutaneous findings frequently occur later and include patchy vitiligo (especially common on the eyelids, low back, and buttocks), poliosis (a localized patch of white hair, which may involve the eyelashes), and alopecia, often involving the head and neck. Common findings include serous retinal detachment Retinal Detachment Retinal detachment is separation of the neurosensory retina from the underlying retinal pigment epithelium.

Early treatment includes local and systemic corticosteroids and a cycloplegic-mydriatic drug. Many patients also require noncorticosteroid immunosuppressive drugs (eg, methotrexate, mycophenolate mofetil).
Tubulointerstitial nephritis and uveitis syndrome (TINU)
TINU typically presents with nongranulomatous acute bilateral anterior uveitis, though it is frequently accompanied by posterior complications, including edema of the optic nerve and macula. It most commonly affects adolescent females but can present at any age. Symptoms include eye pain and redness, decreased visual acuity, and photophobia. Patients may have a history of viral prodrome symptoms and also flank pain, polyuria, and nocturia.

Treatment with oral steroids in the acute phase and use of noncorticosteroid immunosuppressive drugs (eg, mycophenolate mofetil) for chronic disease is often necessary.
