Childhood Chronic Idiopathic Uveitis in a Multicentre International Cohort.

ABSTRACT

IMPORTANCE Idiopathic uveitis makes up around 50% of non-infectious uveitis but the clinical characteristics in children are poorly understood. OBJECTIVE: To report the demographic, clinical characteristics, and outcomes of children with idiopathic non-infectious uveitis (iNIU) in a multicentric retrospective study. RESULTS: There were 126 (61 female) children with iNIU. The median age at diagnosis was 9.3 years (3-16 years) . Uveitis was bilateral in 106 patients and anterior in 68.At onset,impaired visual acuity and blindness in the worse eye were reported, in 24.4% and 15.1% patients but at 3 years of follow-up, there was a significant improvement in visual acuity (mean 0.11 SD ±0.50 vs 0.42 SD ± 0.59 p < .001). CONCLUSIONS AND RELEVANCE There is a high rate of visual impairment at presentation in children with idiopathic uveitis. The majority of patients have a significant improvement in vision, but 1 in 6 had impaired vision or blindness in their worse eye at 3 years.

This is a large retrospective study of children with chronic idiopathic uveitis,There is a high rate of visual impairment at presentation in children with idiopathic uveitis. Although visual acuity improves during follow-up, one in six still had impaired vision or blindness in their worse eye at 3 years.At 3 years, more than half of patients were on immunosuppression and one-third were on a biologic agent.
