Fuchs uveitis syndrome (FUS) is typically a unilateral, chronic, low-grade 
inflammation of the anterior segment which manifests in young adulthood. It is 
underdiagnosed because of its variable clinical spectrum. Although it can mimic 
various forms of anterior uveitis, it is important to make the correct 
diagnosis, based on clinical grounds, because both the management and prognosis 
differ from those of other uveitides. While its etiology remains unknown, it is 
possible that the disease has multiple causes that lead through different 
pathogenic mechanisms to the same clinical entity. Although many patients do not 
require treatment, it is not a benign condition, as often perceived. The high 
incidence of glaucoma makes it mandatory that all patients with FUS should be 
screened at regular intervals, even if they are not being actively treated and 
are relatively asymptomatic.
