title: [Uveitis diagnosis characterization at a referral centre in the area of Barcelona, Spain].
abstract: OBJECTIVE
  To describe the uveitis pattern in our geographic area. Recent demographic, environmental and scientific changes can determine uveitis pattern changes, which we aim to investigate.
  
  
  METHODS
  A cross-sectional study between 1(st) January 2009 and 30(th) June 2010 was done. All uveitis patients visited at our institution were included. Anatomical (IUSG & SUN) and aetiological patterns (by "tailored" tests), age, sex, origin and laterality were analyzed. Results from first visits and controls were compared statistically, by chi-square and ANOVA tests.
  
  
  RESULTS
  From 416 patients included, 150 (36%) were anterior uveitis, 128 (31%) posterior, 101 (24%) panuveitis and 37 (9%) intermediate uveitis (IU). Fifty-six percent (236) were bilateral, mean age was 46 years (6-87) and 58% were women. Fourteen percent (58) were from non-Spanish origin. By aetiology, 20% were unclassifiable, 31% infectious, 26% associated with systemic immune diseases and 23% were ocular specific syndromes. Among classified causes, herpes virus (11%), Toxoplasma (8%), Behçet (8%) and tuberculosis (6%) were the most common. IU were diagnosed more frequently at first time in foreign patients (P=.018); they affected younger patients (P=.008), were more chronic (P=.003) and unclassifiable (P=.024).
  
  
  CONCLUSIONS
  In our area, 80% of uveitis can be correctly classified. IU have an increased frequency among foreigners, and they use to be unclassifiable and chronic. Tuberculosis (6%) and Birdshot chorio-retinopathy (4%) must be kept in mind as uveitis causes.
