## 문제

A 7-year-old child with juvenile idiopathic arthritis (JIA) is being assessed during a routine clinic visit. Which assessment finding would be most concerning and require immediate nursing intervention?

## 보기

1. Morning stiffness lasting 30 minutes in bilateral knee joints
2. Mild swelling and warmth in the wrist joints bilaterally
3. Fatigue and decreased activity tolerance during school hours
4. Sudden onset of severe eye pain with blurred vision and photophobia **✔ 정답**

**정답: 4**

## 해설

Sudden eye pain with blurred vision and photophobia indicates uveitis, a serious ocular complication of JIA requiring immediate ophthalmologic referral to prevent vision loss. Other options are expected JIA symptoms manageable with routine care.

Understanding the Clinical Priority

This question tests your ability to recognize an acute, vision-threatening emergency in a child with a chronic rheumatologic condition. Juvenile idiopathic arthritis (JIA) is a systemic autoimmune disease, and its extra-articular manifestations can be more dangerous than the joint symptoms themselves. The most concerning finding is one that indicates acute anterior uveitis, which can rapidly progress to permanent vision loss without immediate intervention.

Analysis of the Correct Answer (Option 4)

Sudden onset of severe eye pain with blurred vision and photophobia is the classic presentation of acute anterior uveitis. In the context of JIA, uveitis is the most common extra-articular manifestation, with prevalence estimates ranging from 11.6% to 30.0% [1]. This condition is a vision-threatening emergency because the inflammatory process can damage the iris, ciliary body, and adjacent structures, leading to posterior synechiae, band keratopathy, cystoid macular edema, and ultimately vision loss [1][4]. The sudden onset is particularly alarming because acute uveitis in JIA is often initially asymptomatic or presents with a white, quiet eye; when a child suddenly develops severe pain and visual disturbances, it suggests a rapid, destructive inflammatory flare that requires same-day ophthalmology referral and aggressive treatment with topical glucocorticoids as first-line therapy [1]. Delaying treatment can result in complications severe enough to necessitate surgical intervention [1].

Why the Other Options Are Less Concerning

- Option 1: Morning stiffness lasting 30 minutes in bilateral knee joints is a classic, expected finding in JIA. It reflects the gelling phenomenon of inflamed synovium after periods of inactivity. While it requires management and documentation, it does not represent an acute threat to organ function or life.

- Option 2: Mild swelling and warmth in the wrist joints bilaterally indicates active arthritis, which is a hallmark of the disease. This finding confirms ongoing disease activity and warrants pharmacologic review, but it is not an emergency. Joint damage from synovitis occurs over weeks to months, not hours.

- Option 3: Fatigue and decreased activity tolerance are constitutional symptoms commonly associated with chronic inflammatory diseases like JIA due to elevated cytokines. While these symptoms impact quality of life and schooling, they do not signify an acute, irreversible threat requiring immediate intervention. They are managed through disease-modifying antirheumatic drugs and supportive care over time.

Pathophysiology and Clinical Reasoning

JIA-associated uveitis is typically an autoimmune process driven by CD4+ T cells targeting antigens in the uveal tract. In the rheumatology setting, non-infectious uveitis can be the first extra-articular manifestation of a systemic rheumatic disease, and anterior uveitis is the most frequent anatomical subtype, occurring in 75.4% of patients with uveitis in one cohort [4]. The danger lies in the fact that chronic uveitis in JIA is often insidious and asymptomatic until complications arise; however, an acute presentation with severe pain and photophobia signals a fulminant inflammatory response. This can involve not only the anterior chamber but also posterior segment structures, including the optic nerve, as seen in severe cases where papillitis and macular edema develop . Rapid recognition and treatment are fundamental to reducing morbidity, as emergencies in pediatric rheumatology can be misdiagnosed and lead to poor outcomes if not promptly addressed . The nurse's immediate role is to recognize these red-flag symptoms, halt any further assessment that delays care, and facilitate an urgent ophthalmology consultation.References (research sources)

## 임상 시나리오

JIA & Acute Uveitis: Emergency RecognitionPrioritizing Vision-Threatening Extra-Articular Manifestations
In a child with Juvenile Idiopathic Arthritis (JIA), the sudden onset of severe eye pain, blurred vision, and photophobia is a vision-threatening emergency indicative of acute anterior uveitis.

Immediate action requires a same-day emergency ophthalmology referral. First-line treatment is intensive topical glucocorticoids to rapidly suppress inflammation and prevent irreversible structural damage such as posterior synechiae and band keratopathy.

CautionDo not be falsely reassured by a "quiet" white eye; uveitis in JIA is often asymptomatic initially. Any report of visual disturbance, even without obvious redness, requires prompt slit-lamp examination. Delaying treatment can lead to permanent vision loss.

## 핵심 개념

- **Acute Anterior Uveitis** — An ophthalmic emergency characterized by sudden onset of severe eye pain, blurred vision, photophobia, and redness due to inflammation in the anterior chamber, which can rapidly lead to vision loss.
- **Juvenile Idiopathic Arthritis (JIA)** — A chronic autoimmune inflammatory disease in children under 16, often presenting with joint swelling, pain, and stiffness, and associated with extra-articular manifestations like uveitis.
- **Morning Stiffness** — A classic symptom of inflammatory arthritis like JIA, characterized by joint stiffness upon waking that typically improves with activity.
- **Posterior Synechiae** — Adhesions between the iris and the lens capsule, a complication of anterior uveitis that can lead to increased intraocular pressure and secondary glaucoma.
