Silent uveitis in oligoarticular JIA: a 3-hour drive to the slit lamp
A 5-year-old girl has had a swollen right knee for 3 months with 20 minutes of morning stiffness. She has no eye complaints and vision seems normal to her mother. ANA is 1:640, ESR 40 mm/h, CRP 12 mg/L. She has never had slit-lamp screening because "her eyes do not bother her." She lives in a rural area; the nearest slit lamp is 3 hours away, and her mother cannot easily take time off work. The local optometrist offers vision screening only. She is currently taking naproxen as needed.
1. What is her JIA category and uveitis risk, and how would you arrange screening given the travel problem?

She has oligoarticular JIA, ANA positive, onset before age 7, and disease duration under 4 years-the high-risk group for chronic asymptomatic anterior uveitis. Vision screening and symptom review are inadequate; only slit-lamp biomicroscopy detects cells and flare.
The 2019 ACR/Arthritis Foundation guideline recommends screening every 3 months for high-risk children. Rather than letting distance erode this, coordinate: bundle ophthalmology with rheumatology visits on the same day; identify a pediatric ophthalmologist and send a written request for a 3-month schedule; ask the family to plan one day off per quarter in advance. If a visit is missed, reschedule within weeks, not months. Document the risk discussion. Deferring screening because she is asymptomatic is the main preventable cause of JIA-associated blindness.
2. At 4 months, slit lamp shows 2+ cells in the right eye and 1+ in the left, with no synechiae; vision is 20/40 on the right. She is still on naproxen only. What treatment do you start, and why?

This is chronic anterior uveitis, which is often silent and can scar quickly. Start aggressive topical prednisolone acetate 1% hourly while awake, with a slow taper guided by cell counts, plus a cycloplegic to prevent synechiae and relieve spasm. Add methotrexate (about 15 mg/m² weekly, with folic acid) as a steroid-sparing agent, because prolonged topical steroids cause glaucoma, cataract, and growth suppression.
If inflammation persists at 3 months on adequate methotrexate, escalate to a biologic-adalimumab is best supported for JIA uveitis. Check intraocular pressure at every visit. Treat both eyes even though the left is milder. Naproxen helps the joint but has no meaningful role in controlling uveitis; do not let its use create false reassurance.
3. The mother asks whether the eye inflammation can simply be watched and whether naproxen can be stopped now that the knee is better. How do you respond?

Watching is unsafe: asymptomatic uveitis causes permanent synechiae, cataract, glaucoma, and amblyopia. The right eye already has 2+ cells and reduced vision, so treatment is urgent, and adherence to both topical steroids and methotrexate is essential. Explain that the eye can be actively inflamed while appearing white and comfortable.
Naproxen controls joint symptoms but does not protect the eye. If the knee has been quiet for months, it may be reasonable to taper naproxen with rheumatology follow-up, but that decision is independent of the uveitis plan. Emphasize red flags (photophobia, blurring, redness) while stressing that absence of symptoms does not permit skipping slit-lamp visits. Provide written instructions and a school letter.
