Uveitis and psychological stress.

Uveitis is an inflammatory condition affecting the eye and is often associated with systemic autoimmune disease. A role for the involvement of psychological stress in autoimmune disease has been widely demonstrated. However, uveitis is not classified as an autoimmune disease, and a definite or direct cause has yet to be identified, although infection may be involved. Many uveitis patients retrospectively report stressful life events occurring prior to the onset or recurrence of uveitis. However, only a small number of studies have explored the potential association between psychological stress and uveitis, and their findings are somewhat contradictory, many showing that the experience of uveitis itself results in stress. The present article reviews what is currently known about the relationship between uveitis and psychological stress.
