Material and methods: A cross-sectional, descriptive, population-based multicenter study was conducted. The selection criteria consisted of having a diagnosis of uveitis. All data were collected from existing information in medical records.Clinical information was collected in all cases that had a diagnosis of uveitis, regardless of its etiology, in participating centers from the date of the study to the end of the following year. All patients underwent a complete ophthalmological examination, which included assessment of their visual acuity, biomicroscopy, applanation tonometry, and indirect ophthalmoscopy. Results: During the study, 389 cases of uveitis were registered. The prevalence was 58.7 (95% confidence interval [CI] 53.0-64.9). The mean age was 47.0 ± 20.6 years and 57.8% were women. The most prevalent anatomical pattern was anterior uveitis (54.2; 95% CI 48.1-60.8). For adults, the idiopathic group constituted the highest prevalence (31.7; 95% CI: 27.1-36.9), while autoimmune etiology was most frequent for children (10.6; 95% CI: 5.8-17.7). Conclusion: The results of this population-based study offer a representative estimate of the magnitude of uveitis in this area of Spain.engUveítisPrevalenciaSignos y síntomasjournal article10.1080/09286586.2020.1815802restricted accessOftalmologíaEtimologíaEnfermedad
