OBJECTIVE The aims of this study are to examine in our juvenile idiopathic arthritis (JIA) population: 1) the prevalence and characteristics of uveitis, 2) the complications and outcome of uveitis, 3) prognostic factors, and 4) the adequacy of the current ophthalmologic screening guidelines. METHODS Retrospective analysis of medical records. RESULTS 1) Of the 153 JIA patients included, 27 developed asymptomatic anterior uveitis (17.6%) - 7 unilateral and 20 bilateral. The 27 uveitis patients were significantly younger at JIA presentation than the 126 JIA patients without uveitis. 2) The following uveitis complications were noticed: glaucoma, cataract, posterior synechiae, cystoid macular oedema and papillitis. A visual outcome was acquired in 25 patients - 21 patients had a known visual acuity of > or = 0.1. Four patients had a visual acuity of <0.05 - 3 unilateral and 1 bilateral. 3) Female gender could not be confirmed as an independent risk factor for uveitis, neither was Anti Nuclear Antibody (ANA) positivity. We did not find a significant relationship between the moment of clinical remission of arthritis and of uveitis. 4) When applying current uveitis screening guidelines to our JIA population, we found that the optimum screening regimen would consist of a combination of the higher screening frequency of Southwood (1) and the longer screening period of the American Academy of Pediatrics (2) (AAP) screening guidelines. CONCLUSIONS Uveitis is often encountered in JIA patients. It is a serious cause of morbidity. The use of disease-modifying antirheumatic drugs (DMARDs) probably has a positive effect on the preservation of visual function. We recommend a uveitis screening regimen which combines the AAP and Southwood guidelines and which includes rheumatoid factor positivity (RF+) and systemic onset patients in the quarterly screening.
