Juvenile idiopathic arthritis-associated uveitis

Area of Science:

• Ophthalmology
• Rheumatology
• Immunology

Background:

• Juvenile idiopathic arthritis (JIA) is the most common rheumatic disease in children.
• JIA-associated uveitis is the most frequent extra-articular manifestation of JIA.
• Uveitis in JIA is a significant cause of morbidity and potential vision loss.

Purpose of the Study:

• To review the epidemiology of JIA-associated uveitis.
• To discuss the pathogenesis, presentation, and diagnostic criteria for JIA-associated uveitis.
• To outline current management strategies and screening guidelines for JIA-associated uveitis.

Main Methods:

• Literature review of JIA-associated uveitis.
• Analysis of epidemiological data.
• Synthesis of current clinical guidelines and treatment approaches.

Main Results:

• JIA-associated uveitis, predominantly chronic anterior uveitis, is often asymptomatic.
• Autoimmune mechanisms involving CD4(+) T cells are implicated, but pathogenesis remains unclear.
• Complications include cataracts, glaucoma, band keratopathy, and macular edema.

Conclusions:

• Early screening and prompt treatment are vital for preventing vision loss in JIA-associated uveitis.
• Systemic immunosuppressive therapies, including methotrexate and biologics, are increasingly favored.
• Management focuses on controlling inflammation and minimizing corticosteroid use to prevent complications.
