ABSTRACT

Uveitis can be defined as any inflammation affecting the uveal tract, although in clinical practice this term includes any intraocular inflammatory event. The etiology of this inflammation can be related to an endogenous mechanism in the clinical course of a systemic disease (sarcoidosis, Behçet's disease, multiple sclerosis, Vogt-Koyanagi-Harada disease, etc.), or an isolated ocular entity. Sometimes, ocular inflammation is the initial manifestation of an undiagnosed systemic disease. On the other hand, ocular involvement could be the main cause of morbidity of the disease, and early diagnosis and treatment is an important issue in order to avoid irreversible ocular damage. In this article, the authors review some relevant clinical, diagnostic and therapeutic topics related to the most common non-infectious systemic diseases associated with uveitis.
