A 3-year-old girl is brought to the pediatrician because her mother noticed swelling of the right knee and left ankle for the past 9 weeks. She has been walking with a slight limp but does not appear to be in significant pain at rest. She has had no fever, rash, or changes in energy or appetite. There is no family history of psoriasis or inflammatory bowel disease. On examination, she is afebrile and well-appearing. The right knee and left ankle are mildly swollen with mild warmth; the remaining joints are unremarkable. No tenderness at the Achilles tendon insertions or plantar fascia bilaterally, and no hepatosplenomegaly or lymphadenopathy. Slit-lamp ophthalmologic examination reveals cells and flare in the anterior chamber of both eyes; the child reports no eye redness or pain. Laboratory studies show: WBC 10,400/μL, hemoglobin 11.8 g/dL, platelets 385,000/μL, ESR 41 mm/hr, ANA 1:320 (positive), RF negative, anti-CCP negative.
Which of the following most accurately identifies this patient's diagnosis and the most appropriate ophthalmologic follow-up recommendation?
