Anterior uveitis is the most common form of uveitis. There are several known and many possible etiologies for anterior uveitis. After examining the posterior segment and ruling out masquerade syndromes, the main step of etiologic diagnosis is clinical characterization. It is essential to establish unilateral versus bilateral involvement and presence or absence of granulomatous features. Subsequently, a work-up may be obtained which then helps to confirm diagnostic hypotheses based on the detailed history and clinical examination. The priority is to rule out an infection, although less frequent, before starting steroid therapy, adapted to the severity of the clinical picture. Finally, biologics have greatly changed the management and prevention of some forms of anterior uveitis, in particular uveitis associated with HLA-B27 and juvenile idiopathic arthritis-associated anterior uveitis.
