Complications of uveitis in a Spanish population, UveCAM study.

Objective: To estimate the population frequency of uveitis complications and to evaluate their main risk factors in the patients with uveitis from the UVECAM study.

Patients And Methods: Development of complications in 386 patients with uveitis in the whole health area of the province of Toledo (UVECAM study) during a period of 1 year. Description of complications and study of their possible determinants by means of multivariate regression models.

Results: Information on the development of complications was available in 371 of the 386 patients of the UVECAM study. The most frequent complications were posterior synechiae (19.0%), ocular hypertension (14.0%), macular edema (7.5%), epirretinal membrane (6.9%), glaucoma (6.6%), iridian atrophy (5.6%) and cataract (5.5%). The risk of complications increases with age, intermediate and panuveitis locations, and those of chronic or recurrent evolution.

Conclusion: Uveitis is associated with a high frequency of complications, especially in older patients, with intermediate or posterior localization of the inflammatory process and chronic or recurrent evolution.
