SENDAGORTA, E. et al. Uveitis and idiopathic juvenile arthritis in Spain: Epidemiological and therapeutic aspects. Arch Soc Esp Oftalmol [online]. 2009, vol.84, n.3, pp.133-138. ISSN 0365-6691.

Purpose: The purpose of this paper is to describe the frequency and characteristics of uveitis associated with juvenile idiopathic arthritis at a tertiary referral centre in Spain Methods: Review of clinical records. 205 children diagnosed with chronic juvenile arthritis over the last 15 years, of whom 26 presented anterior uveitis. Patients were classified according to their pattern of evolution, the time the uveitis was diagnosed with respect to the onset of arthritis, and the severity of uveitis at diagnosis. Results: The prevalence of uveitis was 12.7%. Of the patients affected with uveitis 71% were girls. The average age at which the arthritis was diagnosed was significantly earlier in the group of patients who developed uveitis (4.06 years). No differences were observed in the incidence of uveitis in girls and boys, nor in pauci/polyarticular affectation. ANA positivity was found in 84.6% of the uveitis-affected patients, this being significantly different to the ANA- group. The average age at which uveitis was diagnosed is 5.87 years. 48.1% of uveitis patients develop uveitis within 12 months of the onset of arthritis. This group presented more complications during the evolution of the condition. A total of 84.7% of the uveitis-affected patients presented with a final visual acuity of >0.5 during the observation period. Conclusions: In our study, the development of uveitis was significantly associated with an earlier age of diagnosis of the arthritis and with the presence of ANA positivity. No differences were observed between boys and girls, or between pauci and polyarticular groups. A greater prevalence of complications was observed in cases presenting with a shorter time interval between the diagnosis of arthritis and uveitis and in those that presented with complications on diagnosis.
