A nurse is assessing a 7-year-old child diagnosed with juvenile idiopathic arthritis (JIA). Which assessment finding would be most concerning and require immediate nursing intervention?

3. Sudden onset of severe eye pain and photophobia **✔ 정답**
4. Fatigue and decreased appetite

Sudden severe eye pain and photophobia indicate uveitis, a vision-threatening complication requiring immediate intervention. Other findings are typical JIA symptoms managed routinely.

Key Assessment Finding Requiring Immediate Intervention

The most concerning finding is sudden onset of severe eye pain and photophobia. This symptom cluster is a hallmark presentation of acute anterior uveitis, a serious extra-articular complication of juvenile idiopathic arthritis (JIA) that constitutes an ophthalmologic emergency.

While musculoskeletal complaints like morning stiffness and joint swelling are characteristic of JIA, and constitutional symptoms such as fatigue are common, acute ocular symptoms signal a vision-threatening inflammatory process. Uveitis associated with JIA (U-JIA) is a well-recognized and potentially devastating condition. The prevalence of uveitis in patients with known JIA is substantial, with estimates ranging from 11.6% to 30.0% [1]. The onset can be insidious and asymptomatic, but an acute flare presents with a painful, photophobic, and injected eye, demanding immediate recognition and referral to prevent irreversible structural damage.

The pathophysiology involves an autoimmune-mediated breakdown of the blood-aqueous barrier, leading to an influx of inflammatory cells and proteinaceous exudate into the anterior chamber. This inflammatory cascade can rapidly lead to complications. Posterior synechiae, where the inflamed iris adheres to the anterior lens capsule, can develop, causing an irregular pupil and obstructing aqueous humor flow, which precipitates an acute rise in intraocular pressure. Persistent inflammation and prolonged use of first-line treatments like topical glucocorticoids both contribute to long-term sequelae such as band keratopathy and cataract formation [1]. In severe, refractory cases where topical therapy and systemic immunomodulators like methotrexate (MTX) or biologic agents (e.g., adalimumab) fail to control the disease, surgical intervention is often necessary to manage complications and preserve vision [1].

From a nursing assessment and triage perspective, the other options do not represent the same level of immediate threat. Morning stiffness lasting 30 minutes (Option 1) and mild bilateral knee swelling (Option 2) are classic, expected articular manifestations of JIA that require ongoing management but not emergency intervention. Fatigue and decreased appetite (Option 4) are common systemic symptoms of chronic inflammation. In stark contrast, a sudden onset of severe eye pain and photophobia (Option 3) is a cardinal red flag for acute uveitis. The nurse's immediate intervention is to stop any further examination that might put pressure on the globe, notify the physician or nurse practitioner urgently, and prepare the child for an emergent ophthalmology consultation. Early identification is critical, and predictive models for JIA-U development incorporate key clinical variables such as age at onset, arthritis subtype, and ANA (antinuclear antibody) status to stratify risk, underscoring the importance of vigilant screening in high-risk patients .

## 임상 시나리오

JIA-Associated Uveitis Screening & Emergency TriageRecognizing the Silent Threat to Vision
A sudden report of severe eye pain and photophobia in a child with JIA is a hallmark of acute anterior uveitis and must be treated as an ophthalmologic emergency.

Immediate nursing action is to notify the provider and facilitate an urgent ophthalmology referral. Do not delay for pain reassessment. The goal is to prevent posterior synechiae, glaucoma, and permanent vision loss.

CautionChronic uveitis is often asymptomatic initially. Adherence to the recommended slit-lamp screening schedule based on JIA subtype and ANA status is critical, even when no eye symptoms are reported.

## 핵심 개념

- **Juvenile Idiopathic Arthritis (JIA)** — A chronic autoimmune inflammatory disease affecting joints in children under 16, which can also have extra-articular manifestations like uveitis.
- **Acute Anterior Uveitis** — An inflammation of the iris and ciliary body presenting with acute pain, redness, and photophobia, constituting a medical emergency due to risk of vision loss.
- **Photophobia** — An abnormal sensitivity or intolerance to light, a key symptom of acute anterior uveitis.
- **Posterior Synechiae** — Adhesions between the inflamed iris and the anterior lens capsule, which can cause irregular pupil shape and block fluid outflow, leading to glaucoma.
- **Blood-Aqueous Barrier** — A barrier formed by tight junctions in the ciliary epithelium and iris capillaries; its breakdown during uveitis allows inflammatory cells and protein to enter the anterior chamber.
