Which JIA subtype has four or fewer joints with uveitis?

• A. Systemic JIA
• B. Enthesitis-related JIA
• C. Oligoarticular JIA
• D. Polyarticular JIA

Answer: (C)

The question tests which JIA subtype is most closely linked with uveitis, especially when only a small number of joints are involved. Oligoarticular JIA is defined by arthritis in four or fewer joints, typically in the first six months of disease. This subtype has the strongest association with anterior uveitis, often in ANA-positive children, and the uveitis can be silent at first. Because of this risk, regular eye screening with slit-lamp exams is important for early detection and prevention of vision damage. While other JIA subtypes can have eye inflammation, the pattern of limited joint involvement plus the high likelihood of uveitis makes this subtype the best answer.
