Abstract: Juvenile idiopathic arthritis (JIA) is a common chronic rheumatologic disease in childhood. JIA-associated uveitis (JIA-U), an important extra-articular complication of JIA, is one of the major causes of childhood disability and blindness. It is predominantly anterior, nongranulomatous inflammation affecting the iris and ciliary body (iridocyclitis) of insidious onset. Recently, American College of Rheumatology (ACR) and the Single Hub and Access Point for Pediatric Rheumatology in Europe (SHARE) have published clinical guidelines for JIA-U. There is no guideline of diagnosis and treatment of JIA-U in China. To promote the standardization of clinical understanding and treatment, the Subspecialty Group of Immunology of the Society of Pediatrics of Chinese Medical Association, Chinese Alliance of Pediatric Rheumatic and Immunologic Diseases, and National Clinical Research Center for Child Health and Disorders organized experts and scholars in related fields to discuss the issue and finally formed this consensus for clinicians' reference.
